excellent, compact, beautiful and clear highs. With the right set of full range speakers this amp is up for the challenge. First class D amplifier I've owned and I cant complain.

Pioneer has certainly perfected the technology allowing class d amplifier to play full range with perfect sound quality giving you massive output with minimal power usage. This amp is a must have, I just replace my Fosgate P500-4 with this baby and I am so happy.

This thing really knows how to put out some power. I have this in my 99 grand prix along with pioneer d series speakers. The highs really sound crisp. It is set up to work as a highs amp so there is no bass but I am going to get some subs hopefully soon.

Owned this 4 chanels amp for one months sor far. Amp is very cool; used with my pioneer FH-X700BT head unit to power my doors speakers:

DB6501 - RMS of 100 Watts in the front

DB651 S - RMS of 55 Watts Midrange.

I love the sound that this amp brought in my car. I bought this map for three reasons ( class FD, very small , and price vs wattage). So far, I am very happy with my purchase. I can't say anything about the durability yet. So my review about the durability does is not final.
