Great Amp for the Price!!!

The following review is for a previous version (P900.4).

This is a great amp! powering four components without a problem! Maxxonics has always been reliable to me! This amp is great for the money! You will be heard!

Great And Underpriced

The following review is for a previous version (P900.4).

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

good amp

The following review is for a previous version (PZT900.4).

I hooked this amp up to two pairs of 8 inch woofers rated for 130w rms per pair (ch.3+4) and a set of 5.25 inch kappa components and 6.5 inch kicker components (ch.1+2a)all in my front doors. Now my mids and highs can keep up with my three 15 inch cerwin vega vmax subs. I was running all them speakers off my deck for a while. I actually melted a tinsil lead on one of my subs cranking my system to the max (was an easy fix) wouldn't have done that if my mids and highs weren't amazingly loud and clean now. This little amp is awesome for the price. Think about the fact that it can run 8 woofers and 4 tweeters and over power three 15 with 1500w rms going to them. Going to build a ported box and add another 15 so the amp can push 2000w rms. Maxxsonics amps have always lasted along time for me.

Best Bang for your buck! Small and Powerful

This amp is the best bang for your buck. It has a lot of power and can easily be bridged and be turned into a 3 channel amp. I have it powering some 6.5 component speakers in my front doors and a JL W3 subwoofer and it does it without a problem. Its tiny and can be mounted pretty much anywhere. I definitely would recommend this to anyone who is looking to buy a 4channel amp.

what an amp!!!!!!!!!!!!!!

The following review is for a previous version (PZT900.4).

i have it bridged in to 2 channels, it is pushing 4 kicker comps 10" subs, there are rated at 150rms and 300 watts peak, and so far no problems running 2ohm loads. A really really great amp for money, only negative is the screw terminals are cheesy.
