Wiring diagram/schematic of the Infinity Spatial systems?

Do we have that info on line here?

And does anyone know the factory part # of the 240 watt amp?

thanks

If you're looking for the amp pinout for the Infinity I system found in second gens, then yes:

More info can be found in the FSM.

What exactly are you trying to do???

Trying to figure out is a parts yard has an Infinity I or II amp on the shelf.

Is there a way to tell, from the number of connectors and pins, which amp might be an Infinity I or Infinity II?

Or is the Infinity II amp a big boxy thing while the Infinity I amp is a flat-ish thing?

Or, does it not even matter? Will an Infinity II amp plug right into where an Infinity I amp used to be without any wiring or speaker changes?

The Infinity II amp mounts in the trunk and was never offered in the Intrepid. The Infinity I amp mounts in the passenger kick panel area. Both amps will require that you upgrade all your speakers to OEM Infinity ones to get the full benefit (the Infinity II has additional speakers the Trep isn't designed for also)...

I've got the Infinity I amp package installed already. Are the speakers that go with the Infinity II different?

I'm looking at the 2002 parts manual, page 08A-310 and with the exception of the rear-door speakers, the speaker part #s appear to be the same.

Not that I'm aware of. At least not the ones that share the same locations as the Intrepid. The Infinity II amp is slightly higher power, but because of the additional channels it's about the same per speaker as the Infinity I system. The programming of the amplifier will be slightly different as well. Why are you looking for a new amp? Did something happen to the one you have???

The sail and door speakers on the drivers door BOTH go out from time to time. When they go out, they go out together.

I can 'bring them back' if I turn the radio up to about 2/3 volume. Then both speakers will run again for a while. No distortion or crackling, just cut outs.

I've swapped speakers with the right side door and the problem stays to the left. Seems to me this means it's either the wiring or the amp.

DRBIII is supposed to be able to generate test tones and read amplifier errors (including speakers/wiring that cuts out), but I don't have access to a DRBIII.

I am trying to decipher the wiring harness info in the parts manual (page 008-1505) to identify any junction connectors between the amp and the door speakers. I'd be inclined to spray some contact cleaner into those connectors (if any). I've already cleaned the speaker connectors themselves.

Weather permitting, I'll probably spend Sunday afternoon chasing the wiring harness back from the door to the amp and radio, taking everything apart and using my favorite contact cleaner *everywhere*.

I see a collection of the Infinity II amps on ebay for less than $50 each. If I could verify that the Infinity I and II amps are interchangeable, I'll probably pick one up.

Infinity II amps are NOT interchangeable with the Infinity I amps. They mount in different locations, have different plugs, different numbers of speakers, etc. If you want to swap stick with an Infinity I amp...
