I was looking for an amp that could provide clean crisp sound, at a low cost. I have it powering 4 6.5's and 2 6x8's full range speakers (VR3's). The amp is set @ 120hz for the front channel and 85hz rear on high pass frequency, with the front and rear gains set @ half. If your looking to build a system on a budget get this amp seriously, you will not be disappointed. The only regret was not purchasing it from Sonic Electronics so i paid about $35 more.
