You heard it correctly folks! This is the easiest and the absolutely cheapest way to install a sub woofer and amp.

I know, and knew while and before installing, that people will be on my case about the two wires I used. Just read through and find out my results!

Other than the sub and the amp (which I didn't really pay for anyways...bartered a detail gig for amp...borrowing sub from dad until I get a new HU to support bigger subs) the install was COMPLETELY FREE!!! It might not be completely free for you though...I just happened to have ALL of the materials lying around in my house and my friends house...this was done over the summer right before school started up again.

Here's what I used:
One old and useless extension cord (had one end popped off and friend's dad was throwing it away)...this is my power cord
4-5 feet of Cat5 cable...this was used for my RCAs

I would make a tool list but the tools you use will vary based upon how your needs.

First step: Deal with your RCA cable
If you don't have an RCA cable then FUCK IT! Make one! My friend is in IT and has a spool of Cat5...why not go to him? We used some solder-on RCA connectors he had in one of his parts drawers. We soldered the ends onto the cable. The cable is roughly 4 feet long and it the perfect size to hook the amp up underneath the driver's seat. There are 8 smaller cables that make up the cat5. We used 2 smaller cables for each connection on each plug...2 for '+' 2 for '-' for each port, left and right.

Second step: Deal with your power cable
Now that you have your RCA cable, time to make your power cable worthy of using. Get as much as you need of it and punch/drill a hole through your firewall. I already had a hole in the firewall. I have NO idea who made the hole, but FUCK IT! I USED THAT BITCH!

Disconnect your battery at this point.

Run the cable through your hole and keep it away from view. In the bay I ran it around the front of the battery, side then behind the battery. This was done to keep minimal slack within all of those moving parts! DO NOT FORGET YOUR GROMMET! This is VERY important. Otherwise you run the risk of vibrations and the tug and pull battle between your engine bay and cabin will tear your cable to shreds and send a nice "thank you" through the body and frame of your A/S. Avoid all of this with a grommet. Mine isn't installed in the picture but was definitely installed by the end of this whole thing.

Since the power cable came out near the column I just slid it underneath the carpet, to the driver's kick panel and right down to the step on the driver's side.


Now you have to hide the power cable in the rest of the van. Since I ran it on the left side of the vehicle I popped off the molding to the step and ran it through the existing bunch of wires. Run it all the way through the molding to end up right behind the driver's seat.

This is the cable starting to go through the cluster. To open the cluster, you have to push down and away on the top of the cluster, or kind of angle a flat head in towards you, pull towards you and tilt away…you'll get it once you see it! DO NOT open the holder like a door (that bitch don't got no hinges!), you HAVE to slide the cables into the cluster or else you risk breaking the holder. Then you'll have to deal with all those cables.

Third step:
Back to that RCA Cable
I went ahead and plugged the RCAs into the head unit and ran it through the back of the head unit and down towards the driver's pedals (shown in above picture). If you have problems with getting the cable through to where it's shown in the pic, take the doghouse off. You'll be able to simply reach in through the back of the stereo bracket and grab that fucking wire.


Same shit, different wire. Run the RCA cable down alongside the power cable and through the same cluster.

This is where the cables come out, right behind the driver's seat. The location is GREAT for installing the amp underneath the driver's seat. By the way, I didn't use a remote wire; I did something easier and more practical for my use. Find it below…

Forth step:
Go ahead now and plug your amp up, make sure your battery is still disconnected. Plug in the power, and the RCAs.

This is for your ground. Trust me, it is THE BEST place to ground the amp if under your seat. I mean its RIGHT THERE! I tested for continuity between the dirty nut, and the driver's doorjamb. Be sure the nut is free of dirt or oil…mine was COVERED in it. I used a wire brush and sand paper to polish up the contact side. Test for continuity one last time through the amp ground port and the doorjamb, if it passes…you're good to go!

I decided to install a switch on the amp. This way I can turn it on and off whenever I'd like to. Sometimes I don't want to blast my eardrums…other times I do…

And yes… that is the switch to a ceiling fan. You thought I was lying about this all being free, huh? Plus I'm keeping in tune with the whole "I drive a 1986" attitude! hahaha

And for the end results...The sound is amazing! The sub sounds great and the power is nice. I really need to upgrade my head unit though. I bought this older model (new in box though) cassette player for $8 off of some lady from Craigslist. People always, and people will, complain to me about using Cat5 cables, but honestly...its only 4 feet of cable. If I were running 100 feet, then I would have a problem. The power cable too, people might say its a bad idea. There are three smaller cables within the power cord and I used two for the power and all three for the ground. I calculated the amount of current I will be drawing, and the power cable is more than capable of meeting my needs. And that's just considering using 2/3 of the cable! Don't even mention using the entire thing!

So, you might not HAVE to do this the cheapest possible way, but...I do :p and just though I'd let you know how I did it. I'm very happy with the system. There is no feedback and people don't even know I cheaped out when they hear the quality.

Let me know what you think!!!

:feedback: :feedback: :feedback:

I needed a brewsky after this one... :cheers:

I've used an extension cord for a power cord before for a friend of mines systemand he used it over a year like that never had any problems

P.S. Never thought of using a ceiling fan switch though :lol:

So long as the wire is of a suitable gauge it will be fine. I've done a few "budget installs" back in the day, they all worked fine(except that one that a buddy & I did when we were 12 and hadn't yet learned about current draw or suitable power sources).

I'll admit it, I too have used an extension cord for power. When you ain't got much money and have a few laying around, use them. Good for low wattage systems.

RCA cable, yuppers. The BEST rca cables are from cat5e cable. You can cut them to any exact length you want and they are easy to route and hide. Twisted pair (Cat5e) RCA cable is great and cheap.

So no, I am not one that is going to knock you about using those wires. I've used them, they work good. They're not the best, but for somebody one a budget, they work just fine. If you're not driving a multi thousand watt system, it'll work great.

I gotta go to radio shack now to get some right angled RCA terminals. Already got 500ft of cat5e cable.

So is the pull chain switch just laying on the floor next to the amp, or did you mount it somewhere clever? I agree with you, I have a box of wires and switches that are left-over or recycled from dead things, and I'll use them if they can handle it. I'm all for cheap, too. Of course, my "cheap" means using the radio that was already installed, so I don't even have to spend my time! :lol:

Very creative, lol....I have only one complaint, and that's 'cause I like everything color coded.......wrap that extension cord for ground in black tape :mrgreen:
Seriously, if it works, if someone else doesn't like it, it's their problemo,not yours! lol
edit.......HEY, I'll swap ya that ceiling fan switch for a toggle, :lol:

Thanks for all the replies guys. I'm glad you're not hating me for cheaping out! hahaha

and I said 4 feet of Cat5...I meant 12 feet haahha! I don't have a clue why I said 4 :p

And Rev! I like my switch and I'm keeping it! hahah

I have it just laying by the amp at the moment. I'm thinking about mouting it somewhere though...don't know where. You got me thinking, maybe I can hook my interior lights to a second cieling fan switch hahaha. But that's after the next project....what what, I didn't say anything about a supposed interior lighting project that is being put together and has been for the past month. what, no...that wasn't me...what? Shit, what kind of lighting project can go on for that long anyways? shiiiiiiiiiiiiiiiiiiit...

I was going to sticky this topic due to it having some good information in it. Problem is, I can't find the sticky button.

BTW, was that a picture of your foot? I dunno if working barefoot gets you more honor but none the less, good job! :thumbup:
Actually, that's my foot! I'm the one that donated almost all of the cables for this project. Scissors and Scotch Tape is my kind of award!

I guess I ought to add some electrical details for all this:

  • The extension cord used was an outdoor 15A cord originally, so using 2 conductors from it makes that safe for (at least) 30A.[/*]
  • The cat5 RCAs are pretty simple, I just took each of the four twisted pairs, stripped them and twisted the pair together, then used the brown and orange pairs as shell/pin respectively to red RCA jacks, and green and blue pairs as shell/pin to black RCA jacks (color coding ftw!)[/*]
  • I offered other kinds of switches from my box of salvaged parts, but that one just seemed right.[/*]

As for the hush-hush lighting project, let's just say it involves about $20 worth of chips and a couple hundred LEDs! (so far, still drawing up schematics...)

It's the thought that counts. Thanks a lot!

Yes, Like the ShAgSTRO says...

Welcome Aboard.

PS Great First Post.

Good job. Very clean in hiding all the wires in the plastic molding. The light switch is a good idea, I just know that I'd forget to turn it off when I'd get out of the van. I had lighted switches in my dash to turn the amps off and still forgot to turn them off once. Good thing I had two batteries.

There's only one thing you left out. The speaker wire to the sub. It looks like awful nice wire. If you have any extension cord left, you could always use that. :).

Edit: realized this was already stickied.

Nothing wrong with extension cord, looks like 16g, probably heavy enough.

The manual switch for the 'remote' wire on the amp is likely to be a problem some day.

If you forget to turn it off, you have a parasitic draw on the battery... sure an amp switched on without an input does not draw a lot of current... but it draws some. If you hooked it to a 'switched' source it would work...

OR, you could just use the 3rd wire in the cord to carry the 'switched' current from the radio.

Nice install and setup there... what are you running? what deck you going to put in ?

I've got some 15 - 20 year old amps and sub from ohhh when I was a teen, going to pop them in this summer hopefully... I think its like 2x 250 for front I got and a 300 for the back or something like that...with pioneer in the mids of it all.

just fyi. home wires are made for high voltage low amperage (110 volts, 5-10 amps)
car wires are made for low voltage high amperage(14 volts 60-120 amps)
normally you should follow the amplifier's recommended specs for wiring depending on how many amps it needs

unless you want to have melted wires and possibly fire or just never play bass through those speakers.

you can find power wire almost 100% guarantee at any junkyard for like 5 bucks with the proper fuse.

so for everyone else who is installing an amp don't use house wires lol.

Completely untrue. Wires transmit power in the form of electricity. Wires have a limit on how much power they can transmit. For Example ...

We know that the formula for power is w = V x I, where w is watts (power), V is voltage, and I is current (Amps). I wire that claims it can handle 10 amps @ 110 volts can handle 1100 watts of power. That means you could also supply 110 Amps @ 10 volts because the power being supplied has not changed. That being said, as long as the gauge of wire is the same you will be good to go. The issue you can run into using household wire is that it tends to not be very flexible. Whereas welding wire which most people use in-car audio installs is very ductile.

This is awesome. I used to like big sound systems, but now I think that I will be happy with just a set of 6x9's and a headunit with bluetooth/aux input.
Maybe a small amp to power the 6x9's. I'll buy it all used and I don't think that I can put more than $100 into it.
It will also have to go in after every single mechanical issue is addressed and I'm confident that my van is at it's current best.

Especially because I don't listen to hip hop anymore, and because the electronic music I listen too doesn't go that low on the frequency spectrum.
At my peak, I had an 3000 watt (real professional audio equipment not false adveristing) amp and a 50lb subwoofer. Some guy who was sponsored by car audio places just gave it to me for like 1/3 of it's value because he was just trying to get rid of it and he got it for free. I knew that I was lucky and that literally any person would have immediately picked that up.
I think the whole system was wroth about $4000 but I got it all for just under $1000. That sub would melt your face off.

However, the fact that you got this done so cheap is really cool, and having a sound system is sooooo cool.
I may make a similar post for a very small 6x9 build. Maybe I can do it all for < $80.

I think that the coolest thing about this post is the fact that you installed an on/off switch for the amp, because sometimes you just want to chill lol.
Pretty awesome.
