BK520.4‏ in Dallas,tx

I've had this amp for a little over 3 weeks and it is doing a wonderful job. ive got it pushing 4 speakers all at 4 ohms and it sounds great. no distortion. The tunning options allowing you to adjust it to your speakers and it doesnt run hot even when you approach the max setting on the gain. My only gripe (minor) is the encaps on the amp. They protrude out over the controls so it makes it a little harder to adjust your settings once you get it mounted. So keep that in mind if you are tight on space. Overall im happy and would recommend this amp. Keep up the good work PPI.

Acceptable, but not impressive

The amplifiers are fully functional but do not produce anything near the power they claim. Despite providing a strong signal and maxing the gain, two of these BK520.4 (claimed 760 watts RMS over 4 ohms resistance), my system's 30A fuse (blows at ~400 watts) hasn't even gotten warm. They work fine for the price, but I wouldn't bother recommending them to a friend.

Love it

I am very happy with this amp. It gives my speakers a very clear sound. I highly recommend this amp to any one on a tight budget.

Great quality amp

I am very happy with my purchase of this amplifier and love the sound quality it puts out way better than my a400.4 fosgate it replaced puts out cleaner more powerful sound has great detail and control I have it on infinity kappa components up from and coaxils in rear just a great amp over all would not mind paying 2-3 times the price for this quality. I have had many 4 ch amps before and would say is the best one I have owned yet. Thanks again to sonic electronix for yet another great offering on their site.
