Great Amp

One of the best amps out right now I believe they do rated at 12.5 and at 14.4 you'll see a significant increase in power on the mono series and multi channel ones. My mid's and high sound crisp clear and loud off of this amp will definitely continue to use crossfire.

Very STRONG amp

This is a clean sounding, very strong 4 channel amp. Just look at the 90 amp fuse rating compared to the others

No bridge switch, so bridging the amp is as easy as putting the wires in the proper terminals

Amp is rated at 12.5, which is a big plus

Just one thing to be aware of is that the built in crossovers don't have an x10 multiplier, so you can't run active without an external crossover
