I took out my rear AC and used the vacated space for Amps.

Thanks for all the ideas. The compact amp in the stock position is very appealing - I didn't know that there were any with decent power that would fit there - I'll look into that more.

I believe some people are using the Picasso Nano amplifier. It is small enough to fit in the stock location: http://soundstream.com/store/car-aud...sso-nano.html/

It's never quite that simple though

In the door would make the most sense for passive crossovers I think... Quite a bit of room behind the trim & outside the door cavity, you need to wire back to the 6.5" units but in terms of # wires I think it's a wash. Would be better to have an active crossover splitting to different amp channels for the 6.5" though I would think.
Rennlist examples - (not mine) but mine are located here too.

Currently, the two smaller speakers on the rear panels are not wired. I have space for two of the compact amplifiers, so I was wondering if I shouldn't put both a 2 and 4 channel amp in:
4 channel:
- 2 channels for the door speakers (via their crossovers) (front phonos)
- 2 channels for the (original) smaller speakers in the rear panels (rear phonos)
2 channel:
- Rear panel 6" speakers (rear phonos)
That way, I'd have higher power for the larger speakers and the ability to adjust the front / rear balance, which I miss. I have a small (powered) sub coming to go inside the spare wheel, for a little low-frequency in-fill.
Is it only the original 6.5" speakers that are 2 Ohm? If not, I might need to put the original speakers (the 2 in the rear panel) on the 2 channel amp. That will be longer-term, as they will probably need refoaming.

You don't have to give up the spare to use the spare tire well for an amp as long as you don't require a larger powerful amp. I have an older Orion Cobalt 304 4 channel amp sitting in the spare tire and it fits perfectly. It's held snug by the wheel itself and I still have room for some extra belts. This location is great for running power from the battery and it's easy to lift it out and set it aside if I need to get to the battery. I've never had any heat buildup problems either.
I use 2 channels to power the 4 front and rear speakers, and the other two channels bridged to power the sub which is in a separate box. You lose the ability to fade F/R doing this, but that hasn't been an issue and the sound is awesome!
I'm planning to repeat this setup in my 87 since it works so well.

I got an amp (Blaupunkt) that just fit on the passenger's parcel shelf:

But I didn't want it exposed, i wanted it to look "normal", like this:

Which I achieved with a small piece of masonite and some trash:

The stock speakers horizontal on top of the rear quarterpanels are particularly crappy ones - you need replacements - or just don't use them. Challenge is that that location has very shallow mounting depth.

If I was doing this project again today (as opposed to buying the amps and letting them sit for three years due to life) I would probably do it differently. The Picasso Nano amps look interesting. I remember running across those when I got back to my project and deciding to use what I already had acquired. I would, though, download the full manual and make sure that the power spec is at a very low THD. I've found that some manufacturers play games with the power spec vs. THD.

Worf, that looks very impressive. Well done.
