Nice features, rated power, but gets too hot

This is a nice amp with great features that puts out rated power (tested with a multimeter and oscilloscope). You would be hard-pressed to find similar features at this power class and price point. Unfortunately, there is a reason: this thing gets too hot! Bridged @ 4-ohms for 420W RMS (which it actually does), this amp goes into protection mode after about 30 minutes of heavy use. At low volume or with cool air (A/C from the cabin) flowing across it, it is fine, but in the trunk mounted to the back seat (where most subwoofer amps would go) it overheats and shuts off. I added a couple 120mm fans to help alleviate this, and while it does help, it still shuts off occasionally when it is 100+ degrees outside. For this reason alone, I can not recommend this amp unless you can mount it inside the cabin with some airflow across the heatsink. Once this gets fixed, PPI will have a definite price:performance winner.

For any naysayers, yes, the appropriate sized cable was used (4AWG) with good bare-metal grounds (checked with a DMM), the gains were set correctly using an oscilloscope, and it was not stuffed in a space with no ventilation. There is absolutely nothing wrong with the install (not my first rodeo), it is the amp itself.

good quility amp no made up max power numbers

With all the "1000w max" or whatever amps on here people probly pass this one up seeing 420w but this amp is bigger and heavier then alot of these off brand 2000w whatever amps on here. This amp probly actually puts out steady what it says maybe more, not some amp that made 3000 watts @ 20v for one second before it was destroyed in a testing facility.

Have it pushing one orion xtr 12 dual 2 ohm sub in my friends lancer and its obnoxious. Easily mistaken for two decent 12s.

Low pass filter settings dont make much sence compared to most amps so i have it 3 stars for ease of use. also im not a fan of these style terminals for power wire, but they do hold secure.

Great value & power for the $$$

Bought this amp for 2 kicker comps and it's more then enough. I know it's not a Dclass amp but I got it bridged to 2ohms pushing between 600-800watts with the gain just over 1/2 way up & the remote gain control is great. I highly recommend this amp for anyone who wants some good bass for their $$$ unless u r running more then 2-3 speakers or going for competition level bass, this is all u need. PPI still has that real power.
