great product for your money.

great sound very easy to hook up and its a awsome amp would recmend to my freinds and family.

awesome amp, exactly what i anticipated

when it says its 900 watts and it says its bridged 2 channels @ 450 each rms u know basically all of the ratings rms are like double overated. i feel like im getting maybe around 60rms x4 @4ohm, dont got a meter but if they put anything near what they claim my speakers would all be abused or blown.

if u need some extra power for your 4 main car speakers, this should be more than enough, was for me and i love loud music.. its probably enough to make u deaf quick lol, yet very clean clear power. its okay we can always turn the gain down to not murder our eardrums.

additionally i dont see why anyone would ever need a 4 channel amp louder or more watts than what this one truly puts out because this is loud as hell lol. i bet if i drove by another car full volume they would feel their volume is maxed in their own car lol. just with probably 1 window down lol.

maxxsonics makes good quality amps, as long as u know what those true specs actually are. this is my first crunch amp, but i've been a hifonics brutus amp fan. I would recommend this amp to anyone.

Great Deal

For the money I don't think I could have bought anything better than this. I also bought another crunch mono block to push my subs. I'm completely satisfied. You wouldn't believe how well the system sounds for no more money than I have invested in it. Thanks Sonic.

Can't beat the price!

This amp is actually pretty good. I use it to run 1 sub and 2 five and a half 2-way speakers. I plan to use it for just my highs later. The price and quality at this time fits my budget.
