Speaker sounds cheap

Comes with two harnesses with RCA connectors. The speaker rattles sometimes.

Kit needed to install car stereo

Needed to install JVC KD-HDR60 into Chevy Cobalt sedan. The instructions for self-install were fairly clear and installed easy enough. Still no problems after 6 months!

Not worth it even for free

Not a good adapter if running a deck with iPod capabilities. Burned out in two weeks of light use. I'll keep my deck hard wired.

Works Great

It matched right up with my Cobalt's harness and the color coding match my aftermarket head units, so everything was good. The speaker for turn signal and open door is rather cheap and because my car has one built in, i was able to just cut the speaker out and everything was good.

Only for Cobalts/G5's

This is the only easy to use and working GM converter to retain door chimes. I love it works flawlessly and allows volume control of door chimes.
