Everyone keeps telling me that the amps are on the drivers side rear speaker, but this is not true! There is no black plastic contraption, both of the rear speakers look exactly the same. I even fed an amped signal to the wire that connects to the speaker, and it worked fine! So where is it? Is it part of the amp that powers the sub? Is there any chance that the head unit actually powers it? UGGGGGGgggggggg. help please.
Thanks

It probally is with the sub amp.

I'm doing some audio work on my Roadster, and I discovered something interesting. I had been wondering where the amp was for the rear speakers, and for the sub-woofer.
I do not have the "Bose Upgrade" with the CD changer. I have known for awhile that the front speakers are powered by a small amp in the head unit.
I have seen the pictorials showing the position of the speakers in the roadster and coupe, and they have also shown where the amp is.
No one could tell me where the amp is, in the roadster.
While taking apart my car, over the past few days, I made an interesting discovery.
This is the amp for the rear speakers and the sub-woofer, in the non-Bose upgrade roadster.
It's on the back of the sub-woofer.

Here is the whole set-up.

It is a dual amp configuration of a Philips TDA8563Q 2x40W amp chip. There are two of these "chips" on this board. One amp runs the sub-woof, in a dual voice-coil mode, the other, runs the two cheap-o rear speakers. These guys.

Here is the OEM Sub-woof, a real cheap 8" basic speaker.
