Stereo install to a 1991 Camaro convertible

"Once again, Rockville has exceeded my expectations. Where can you get an amp for this quality for this amount of money. I did a boat install a couple years ago with all Rockville and could not be happier. That’s why I came back to Rockville again. My only small complaint is I didn’t do enough research myself. I assumed this amp came with a USB input like my very similar boat app had. Kind of wish I would’ve went with the boat amp, even though it was for a car install."

— Kyle L. (5/5)

Good amp

"Great amp, I feel that a lot of thought and delivery are added to this amp, and it shows!"

— Clayton B. (5/5)

Good experience

"Though I haven’t installed the amp yet, I have made multiple purchases with Rockville and have been pleased with the product and the service I’ve received so far. Helpful information that has helped a novice create some nice systems."

— Shane T. (5/5)

So far so good good.

"So far so good good. Very good quality and good price point."

— Darren G. (5/5)

Wire kit too small

"They send a 4 gauge wire kit with this amp. The owners manual says to install no smaller than 0 guage. I called to remedy the situation and they keep saying “too busy to accept the call” they shouldn’t send a wire kit in a bundle deal that isn’t even compatible with the amplifier"

— Michael F. (1/5)

Loud enough.

"Using with line output converter to keep factory radio, what a difference! Don’t need to rattle windows but every once in awhile, just want to crank it up. This amp will do it. First time to install an amp, wasn’t difficult at all. Read instructions, watched a lot of vids, hardest thing was routing cables and finding proper mounting place. In process of building sealed sub box, can’t wait to bring that #5 channel on line. Will give 5th star after I’ve had it for awhile."
