Tough Amp

The following review is for a previous version (CX650).

This is a tough little amp, that's for sure. I bought this to revamp the audio system in my CRV and then about a month later I got into an accident with a deer. The amp went from under the passenger seat into the trunk, pulling wires and terminals with it. It survived and it is living a life of luxury in my Grand AM.

Pros: It has a auto-shutoff for detected shorts
Powerful amp, high wattage
Included, individual bass controller

Cons: This is the first amp I've ever bought but it seems a little on the large side.

Overall, this is a solid amp with alot of power that can take a beating. Definently recommend.
