My '04 has the 8 speaker setup and one of the front door speakers are shot. Previous owner replaced the head unit with cheap aftermarket, but im not a fan and will likely replace again.

Ive upgraded speakers in every vehicle ive owned, but this one is a bit more in depth then im used to. Seems most of these (all?) are one way/component style with high or low pass filters. Never dealt with those.

Im not looking for high end/audiophile quality...just fuller sound. Perusing Crutchfield, I see most of the sizes listed so that helps.

Ok, so my questions...

Would it be best to stick with component style? If so, using the factory wiring (hopefully), would I need to purchace seperate filters for each speaker? Are they all one way?

The factory amp...can/should I reuse it for the new speakers? Any idea what kind of power it puts out?

Are the Crutchfield specs correct? Anyone know what tweeter size fits well in the door (they dont have a size for that)? I dont mind modifying the openings a bit to fit something larger...if its better. That said, i hope to button it all back up with the factory grilles.

And can anyone school me on the actual wiring (These in series, parallel? How many channels are there? What ohms should I be looking for?).

Thanks in advance!

Here's the wiring diagram for the 04 without RSA

Ooo, thanks! That should come in handy.

RSA=the amplifier?

Optional Rear Seat Audio Controller

If you have that the wiring is slightly different.

 

[foxfire]

Nope, no rear controls.

The diagram is helpful, but there's more specifics I need before I can put a purchace together.

Hasn't anyone upgraded their speakers?

Foxfire,
I cannot offer any suggestions for replacement speakers.
Speaker upgrades are often done. They are somewhat personal as to choice, and desired end result.
You stated you have done it yourself to several vehicles.
You have seen a wiring diagram, yet you ask if they are in series or parallel.
Speakers are neversupposed to be wired in series.

i know you said that you looked at the crutchfield (crotchfeel) website, but it's a great place to go back and reference to really educate yourself on some of what's available while you come up with your own plan.......
:text-link: https://www.crutchfield.com/car/outfitmycar/mycar.aspx
crutchfield lists the tweeter sizes they sell and state that you will need to modify the mounting to fit the upper front door tweeter location in an astro van.
what does "fuller sound" actually mean to you? - even with new speakers it won't be much louder without distorting, or go boom-boom, with the factory amp.
using 2-ohm vs. 4-ohm speakers will depend on what the amplifier you use is rated for - the factory amps are 4-ohm.
aftermarket speaker kits come with their own crossover networks; the component type speaker crossover is separate.
without going up much in amplifier power the factory wiring will be ok.
crutchfield is probably the most trusted mailorder audio/video company there is. if you don't trust crutchfield specs, look on the speaker manufacturer's website.
how far do you want to go in dismantling the interior for this project ?
for me personally i am working on installing a sound system with Infinity 2-ohm speakers & subwoofers, Infinity amps, and a Sony single din CD head unit.
when i bought my front door speakers i got 6.5" 2-way component type. there is now available a 6.5" 3-way component type - from playing around with my setup i could suggest to you to try this newer 3-way type and put the midranges in the headliner behind the front seats (it might help with that fuller sound you seek) - i'll take a pic & post it later.
in the final analysis, only you can determine the specifics of what you want.......and......how much money do you want to spend ??
:wave:

here's the pic - junkyard bose speakers from a suburban i think....

Don't get 'amp' and 'crossover' mixed up on these OEM stereos.

There is a 'crossover' for the back door "Woofers" - this post will help:

I also searched for g00gull using this:
stereo crossover / amplifier astrosafari.com

Got quite a few stupid hits, but ... better than parallel speaker setups... LOL

That link is super informative...thank you. I noticed that someone mentions in it that conversation bypassing the amp puts the rear speakers in series, and in my previous searches around here I've seen that too. Thats where that question came up. That also lead to the impedance question.

I'm noticing most folks are replacing their factory "woffers" with 2 or 3 way. Every other install I've done, it's been replacing a 2 way with a 2 way (or 3)...which is why i was asking about this component style setup we have in our vans, and if its wise to stick with that style. I've just never dealt with that, though it seems ideal.

As far as what end result I'm looking for...obviously replacing the crackling door speaker. Beyond that, just getting the best sound I can without falling off the deep end. Not "boom boom", but not cheap paper cone either. I have few bucks I can throw at it, I drive a lot, and I like music.

I drive a lot, and I like music.

me too!

If you sroll quickly on this tread pages you will see how i rigged mine , i am no expert and the most of the components are low end but that dont matter much ,at least it may give you ideas maybe .

Resurrecting...cause I still dont really have an answer...

Say I'm leaving everything the same, just changing out the blown speaker (well...the front pair). Should/can I replace it with a 1way, component type, midrange woffer? 4ohm? Something like this:
