Infinity Speaker Relay Location

Hi,
I have a 1991 Dodge Caravan LE with the Infinity speaker/sound system, mid speakers are not working and rear speakers are weak, fronts work fine. Stereo repair shop thinks it is probably the speaker relay, he was unable to find it right off, anyone know the location of it?
Many Thanks!
Rick

I have the very same problem with my 93 Plymouth Voyager and I am looking for the relay. If I find it I'll let you know.

There is a bank of relays above and to the left of the fuse block. You have to take the panel off that surounds the fuses. The speaker relay is number 6 just below 5 (that is empty on mine).
you can go to the following site for info on relays

Anyway my relay is ok. Had already bought a new one and speakers still do not work. Nothing from door speakers and can barely hear the rear even when fade is 100% to rear. I had put a new Pioneer CD/Radio in as other Infinity radio went bad. This one was suppose to work with Infity sound system.
If anyone can help I would appreciate your reply.

Well I got it fixed. I bet your cigarette lighter does not work. Change the fuse it also powers the amps. Mine works fine now.
