Not enough time to test it

The following review is for a previous version (P1-1000.4).

Installed it and a 64 oz. soda was spilled on it the next day . Seemed to deliver on the specified wattage . I disassembled it and it seemed the soldered connections could have been done by a trained chimp as it was very sloppy . Some parts of the board were repaired by making solder bridges . But it was cheap enough and did work out of the box .

Crunch P1 1000.4

The following review is for a previous version (P1-1000.4).

Pretty good quality amp. Only complaint I have is it does tend to get hot easily and turn itself off. I am using Polk MM651's and Polk MM691's in a four channel setup.

The following review is for a previous version (P1-1000.4).

Its a good amp have it using all its juice right now. But ever sense I first started putting it in my car's electrical system has been wigging out, for instance the when I turn my lights on the car starts dinging, now the interior lights will turn on when no one is in it and so on

Great amp for a beginning car stereo enthusiast

The following review is for a previous version (P1-1000.4).

This amp was a great upgrade from running my cab speakers off sony deck. This amp was some trouble like I had to add a 4.4 farad capacitor
and upgrade most of the wiring all the way to the alternator with 1/0 AWG and the last thing I put in was an output converter. Some of this was over kill for my current 1760 watt system but I'm ready for more power. Tweaked right this amp will be perfect when I upgrade every thing to spec. Anyone that wants to put this amp on a 4 AWG wire wait until your ready. I would recomend this amp to a person that wants it done right.
