I have an am-fm 8 track stereo in my 70 SS. I have four speakers and it is listed on the build sheet. A friend recently told me that there should be a component to the system under the rear seat. I think he is mistaken, and is thinking of another car. Which is correct?

He --IS-- Mistaken............DK.

My 70 has the original AM-FM 8 Track and four speakers and there is nothing under the seat.

i have the am with 8 track stereo that comes with factory 4 speakers.
your friend must be thinking about modern cars with sub wooferl:)
who knows were he got that info.
dont worry your car is correct the way it is.

Just installed my system...bone stock and no components under the rear seat except the wiring harness.
