Review by B. Rodgers "Gadget Geek" : Clean sound and unmatched features! 
Paying the little bit extra for this over similar amps can actually save you some money, since the balanced inputs let you use it with stock headunits that send out a balanced signal - usually Bose or other factory premium headunits (not that Bose is premium in anything but price, but I digress). It also accepts both low-level and speaker-level inputs, so purchasing a separate line-output converter is not necessary if you're running it off of a headunit that doesn't have low-level outputs. The signal sensing technology lets you get away without running a remote power signal if using the speaker-level inputs, which is particularly helpful if you are still running a stock headunit which doesn't have such a wire already. So basically, this amp can be connected to any aftermarket or factory headunit without adding anything but power and audio signal wires. As with any amp, make sure you measure the dimensions for where you intend to mount this.
Review by Ariel : GREAT AMP! but even BETTER SHIPPING!! 
This is an amazing amp an you will not find it cheaper anywhere else... I ordered my product on a monday and received it on a Wednesday!! I love this amp and i would only trade it for a HD600.4 amp. Good business.
Review by lechalan : Very Good 
This amp works perfect in every way. You need a very good speaker system in order to really apreciate the power of this... Amazon has the cheapest you will find, i payed over 70 bucks buying it at the JL Audio store...
