Great Amp for the Price!!!

Great And Underpriced

I have this amp and was extremly surprised with the clear signal I had chosen this amp because it was reasonably priced and had already overspent on a Pioneer CD deck and two pairs of Infinity Components. This amp sounds great and last for hours It ids not easily overheated. It has been underpriced and should not be judged by price. It is running 4 tweeters and 4 midrange woofers in a 1998 S10. I'm heard down the block and rattling store windows and displays.
Car alarms will be set off with the right pair of subs

Loud!!!

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.
