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.

This amp has very impressive sound quality and has virtually zero feedback on my speakers ever. If you are like me though and sometimes use your system for tailgating or blasting music, be forewarned this amp will NOT push high end speakers all the way. My Alpine type r components 100 watt rms stop getting louder at 3/4 volume, which actually really isnt that loud. I have tried other 4 channel amps that push the speakers twice as hard (like fosgate 400/4) but I always come back to this because the sound quality is unmatched.

As long as you dont want to pump your system (Like on a boat) this amp will make you happy.

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...

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.
