good amp

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.

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

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.

Solid amp awsome price !

Very good amplifier I have had mine for a 2 years now first one was going strong till it was unfortunately stolen. I have had this exact model as a replacement for about 8 months now and it has been amazing. It has many settings for both front and rear speakers. Accepts 4 gauge for power and grou.d and is very easy to use and tune. Pick this amp up with. Nice set of component speakers and you will not be disappointed!
