I bought this amp as a cheap replacement for my previous one(Boss 400Wattx4). I wasn’t expecting this amp to perform as well as it does. I have had it for 3 years now and it’s hitting just as hard as it did when I took it out of the box. I currently have it running to 3 subs. (1) Rocksoford Fosgate P3D2-12(600 WATT RMS, 1200 WATT MAX) and (2) 12" RE rt pro’s(200 WATT RMS, 400 WATT MAX). This amp has been used almost everyday since I bought for at least an hour a day. It has never had any overheating issues or electrical problems. This amp is hits harder than The Hifnoics Brutus 1500 Watt amps, as well as almost any other 1000-1500 Watt amp. This amp of worth every penny!!
