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

GREAT AMP FOR THE MONEY!

The following review is for a previous version (PZi-125.4).

This is by far the best bang for your buck as far as 4-channel amps go. Great sound, although not as good as you probably would get with a Rockford 4-channel amp. However, RF amps that are comparable to this in wattage and channels are over $400.00! This one is only $89.99! It amps the speakers great, and at the same time has little distortion rates. I couldn't believe it when I hooked it up, because I thought for sure, because of the price and all, it would be a very poor sound quality. This isn't the case at all. If I was to buy a 4-channel amp, and don't want to spend tons of money on one, I would for sure go with this one, or it's newer brother: the Crunch P900.4. It's almost the same thing from what I have heard. Only drops the number of watts down from 125W @ 4 ohms to 115W @ 4 ohms. Not much of a difference. Also, this one has one preout set (RCA Outputs), so you don't have to waste a spot on the back of your deck (or if you don't have room for another set).

All in all GREAT AMP, CHEAP TOO!

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.
