Very Bad Amp

Ive had this amp for a little over 2 weeks hooked up to 12 kicker ds650 and it has given me so many problems. It overheats after about 3-5 minutes of use and shuts off sound. Also it smokes a lot. Idk whether i received a bad amp or something but plz don't waste your money on this amp

Not very good

There was no way this thing was putting out the power it said it was. And it didn't. Switched it out with another amp that was 125x2 and it blew the crunch out of the water. No sound quality or power. I bought it for $125 also. I hate the knobs too. Very cheap plastic and not thought out too well.

CRUNCH QUALITY

I AM OLD, I AM NOT TEENAGER I AM 51, I have owned over 15 amps and I am an Electronic Engineer, I understand Mosfet, and power supplies, and Class AB amplifiers and switching a push - pull and output transistors. CRUNCH MAKES a High Quality product at a very reseanable price. Installed and tested it blew 5 amp fuses with ease
10 amp fuses went about the same time my ears lost hearing.

I bought the 4 Channel Amp because it had the abilty and power to
drive a Sub woofer and two midrange speakers.

MY Sub is a 4ohm 10" Infiintty subwoofer and it thumps very nicely with NO distortion from abrupt amplifier Clipping, the amp just kept running smoothly as sound level was increased.

My mids are 6 1/2" MB Quartz component Speakers and it drove them
precisely with NO audiable Harmonic Distortion

comparable amps - Orion, Pioneer, Alpine but all cost almost twice as much for same RMS Power per channel.

For the money and versatility CRUNCH makes a GREAT AMP!

sounds great

i had this amp hooked to a pair of 5.5inch alpine type s and 2 6x9 alpine type s after about 14 days playing it loud the alpines blew out the tweeter that's molded onto the speaker broke off which is amazing. so i went out and bought some higher power infinities and the sounds quality is now much more crisp and clean its sounds great and i have the infinities for 3 months now. this amp is great i also have a ground pounder 1500w running a memphis mojo m3 15inch which is a killer. this amp is great, cost effective and good sound/power

Great Power

Crunch Amps are by far an amazing product for the price. I have used Crunch Amps in about 5 vehicles. If you want good, reliable power, with a nice clean base I would personally recommend Crunch Amps.
