Awesome amp

Great product at a great price. Super fast shipping. I don't have anything bad to say about this amp other then a few picky things.

PROS: cross over controls on top, runs cool at high volume levels for long periods of time, lots of power to play with, lots of different wiring options, sounds great, looks nice I'm sure there's some I'm missing

CONS: comes with one Allen wrench but 2 different size allens needed (1 for the side covers, which is included, 1 for taking the cover off of the cross over and gain controls) wiring screw downs are philips head they could have made them same size allens as the included wrench, this is a large amp not complaining just making sure you know it's not compact, that's it like I said just being picky.

OVERALL: great amp, I would recommend this to everyone and anyone. This could take the place of a 5 channel if you double up speakers on channel 1 & 2 (speakers need to be single voice coil 4 ohm to drop ohms to 2 ohm load) then bridge a dual voice coil 2 ohm subwoofer (wired at a 4 ohm load) to channels 3 & 4. You can run so many different configurations with this amp that is just one example. BUY THIS AMP!!! You won't be dissapointed. Enough said, hope this helps you with your decision.

WOW!!!! Buy this amp!!!!!!

I have been looking, looking, looking to replace my old sKool Phoenix gold amp, trying to find the perfect combination of SQ, with head room. Well, if you DON'T buy this amp, your MISSING out!!!!! Thanks Sonic for quick shipping, and a STEAL of a price on this amp, now I have to decide... another of the same model for my subs bridged, or the mono Q amp???!! This amp LOOKS very NICE in person, the MB QUART logo lights up in white, and the red checklit, which matches my Audi Red/White interior PERFECTLY!!!! I AM VERY HAPPY WITH THIS PURCHASE 8-)

Read Me!

I tried so many amps. This amp is rediculous. It's not even normal how insanely clean this amp is. Ground loop? Normal hiss? Not with this amp. I have never heard such clean sound in my 13 years of car audio. This amp made me depressed for days thinking about what i've been missing. You can read reviews for all kinds of car audio and never know what to expect because every ear is different and its so selective. NOT WITH THIS AMP there is no human on the planet that could say this isnt a mind blowing expirence. Stop looking around, let this review change your life take a chance on a strangers review and when you hear it and say wow he was right pass the word along to the next guy as a thankyou to me. You are welcome!!!!!
