great 5 channel amp for the price

This amp has to be one of the better 5 channel amps that ive used for the lower end brand names. For being a crunch amp it has more than enough power to give my mids and highs great sound and enough power in the fifth channel to power my 2 10s. ive had this amp for a few months now and hasn't let me down yet. The only thing I would change is the Phillips type screws for all the connections. One started to strip with very little effort. Only one though. Wish it had the Allen type screws like the hifonics amps. Would definitely buy another one of these.

Fine for my needs

I originally ran this bridged, it seemed to distort much earlier running it bridged and the front stage over powered the sub channel that is150 watts. I got rear fill speakers and I am very pleased running all five channels. I paid a pro at an installation shop $35 to set my gains and crossovers on the amp. The procedure is not well described in the manual and it was not sounding very good in spite of a lot of tinkering before I paid the pro.
If you buy this amp understand it is large, 20 inches across (you will need 24 as all the wires and controls are on the ends) and 9 inches wide.

I feel it was the best amp I could get for the money, and would buy it again. The system sounds fantastic now that it is powering 5 channels and is adjusted correctly. It did not make for a good three channel amp as the sub was underpowered in that configuration.

Good Starter amp

I bought this for a friend of mine and installed it in his car. it's well built, sturdy and packs a good punch for the price. You'll get your money's worth. It was an easy setup and it's driving a 10" Pioneer sub without any issues.

I would recommend this unit for anyone looking to install a good looking amp that delivers and doesn't burn a hole in your pocket.

Crunch P1-5050.5 Amplifier Review

Love this Amp. Unfortunately my first one was stolen along with my car. I just purchased a new one. It used to be black with a blue emblem that used to light up. Now it's white with a red emblem. I don't know if it lights up yet. I installed it the first time but this time, I'm going to pay someone to install it for me. Sound is good and crisp. Bass is controllable via a switch you can put under your seat. I had it connected to a 12" sub-woofer and it still had a lot of punch. Since it's a 5 channel amp it will take care of all of your amp needs and save you the cost of buying two.. Also, it never got hot, even when I ran it for hours. Can't wait to have my new one installed on Saturday.
