well worth it

I have owned crunch amps in the past and this amp was no surprise to me, a great amp for the money, you can't beat crunch amps on their value!!!

Junk - It is cheap -You get what you pay for

I bought this to replace an old Sony Xplod amp that finally died after 20 years. I paired this with JBL 6x9 and Polk 4x6. Nothing but distortion. It WAS in my 77 Corvette Stingray but the sound was terrible.Anything adjustment past about 10% simply produced distortion. Ended up taking it out and tossing it. Put in a Rockford Fosgate Punch 300 and the sound is 1000x better. This Crunch is a terrible amp.
