Pros: Good power output, decent warm sound for class D, clean solid design. Everything we have come to know and love about JL Audio is there.

Cons: No built in fuse (so more parts to buy), Mine didn't last a year and just sent it back for warranty replacement. Sound started cutting out intermittantly and then back to normal volume a few minutes later, then cut out. Replaced amp with my Kappa Five while I'm waiting for warranty replacement. Sonic's Service agent said it was defective after testing. (Here's to hoping the new one is better)

Overall: I bought it for the power and it seems to have plenty for my setup ( listed below). The design is not flashy it's a clean conservative look, and the size is perfect for stealth installs. The XD700/5's sound is pretty good although my Infinity Kappa Five has more clarity on the high end frequencies. Kappa Five lacks the power on the Sub channel even though the XD700/5 and Kappa Five are rated roughly the same power-wise.

I will be installing my replacement XD700/5 for sure, I just hope my first one was just one of those things and the new one is what I would expect from JL Audio.

Thanks Sonic Electronics for the easy return / exchange process. I've spent some $$$ with you guys over the years and you haven't let me down.

KW-AVX840 Head, Infinity Kappa 63.9c, Infinity Kappa 693.9I, JL Audio CP212-W0v3 Subs.... Cruisin' in my Impala, Just waiting on more power.

Purchased this amp late last year new from Sonic. It made it only a few months before I started having problems with it, same issues posted by JR on 09/08/12. I sent the amp back to Sonic for repair and got it back 2.5 months later only for them to say "could not duplicate problem". Prior to the return, I did extensive testing on RCA's, Speakers, Passive Crossovers, etc and it is definitely the amp. On a positive note, the amp was pretty darn impressive while it lasted.

This amp is awesome, compact & very clean. Thought about buying another one for wife's car.

What a great amp!!! It is small, but more than able to back it up with ample punch!!! I`m driving 4 Focal splits and two JL 10" subs and it is more than up to the task of powering them all in a small package. Being a full class D, with more efficiency and runs cool. It deifinately has to be one of the best 5-channel amps out there A++++.

Beautifully designed & featured amplifier. Performs magnificantly. Would recommend this amp to any one who needs a compact amp.

Have had this amp installed for about 6 months now with zero problems. It has done everything it advertised it would do and was small enough to easily hide. I would buy this again!!

This amp is not only beautiful but powerful. The amp size is equal to a Nintendo Wii. Yes it is that small but its built tough. I only had it for a couple of days but I love the amp features. I love that the amp is a class d and won't draw a lot of current. The music is nice, clean and very detailed. I have this amp powering (4) rockford fosgate speakers and a Boston acoustics 12 g2 in a sealed box. I look for excuses to drive my car so I can play my music. I have no regrets I am satisfied customer. Great job JL audio.

Ok this amp is great. I bought mine to replace my huge kicker amp. There is no alt. whine or, hiss from the speakers while the volume is low. Very good signal to noise ratio. This amp pushes my entire system with out any distoration, even at very high volume. But the very BEST part of the amp is its size. My kicker amp was 3 times the size. The JL amp fit under my front seat along with a 1 Fared Cap.
