Stock amp

My Iroc has the ERS system, which means somewhere is a factory amp. Question is, where is it? I'd like to install a better amp, and maybe use the stock wiring.

Re: Stock amp

pretty sure most cars got the badge without the system. basically it was just slightly better speakers in the rear. there is no amp

There must be, as none of my speakers worked until I hooked up the (amp?)power wire.

basically I had the wiring kit, but still had to hunt down the amp wire to turn them on.

That's what my IROC has. Just the stereo/cassette with equalizer, no separate amp. maybe the speakers is all.

Re: Stock amp

No - There is no AMP with the "Extended Range Sound" option.

The only Thirdgens that got FACTORY amps were the Firebirds with a the "Subwoofer" system ('GAIN' button on the dash ) or a Camaro with the factory BOSE option. ( says 'BOSE' on rear speaker panel )
