nice amp very flashy

Very flashy really the v flashes this amp is rated at 1800 watts at 1 ohm 900 watts at 2 ohms I was running it at 2 ohms it was not pushing 900 watts rms more like 250ish but it was enough to partially blow one of my 300 watts rms 600 peak with the amp gains all the way up great amp for price but I recommend getting a CEA-2006 compliant amp

Great hard hitting clean power for an awesome price.

I was a little skeptical about ordering this considering the price and some of the other reviews. But now that I have it and have been using it for a while I am impressed at the power of this package. I have to keep the levels down so I can see when I'm driving, otherwise my eyes rattle so much it's all just a blur. At times I think my car is going to shake to pieces. I have the subs installed in a sealed box with a total of 2 cubic feet, subs mounted inverted (on the outside of the box) to use the total space of the box. Box is filled with poly-fill (polyester pillow stuffing). I can't think of a single bad thing to say about it.

Great amp

Amp does exactly what it's supposed to do. Although not a big fan of the wired in bass control

Remember the power supply must be there too

Many who consider themselves experts need to realize that the power supply in the vehicle may be inadequate. The CEA endorsed formula for RMS rating is: 14.4V x amps x amp efficiency % = RMS watts
To blast an amplifier without putting it on a test bench with a REAL power supply is just plain not fair. Clamp testing in a vehicle will tell you what YOU are really getting but not necessarily what the amp is truly capable of. You don't have 14.4 volts in the vehicle to start with, yet EVERY manufacturer uses 14.4 to calculate their RMS ratings. Next you have to consider the output of your alternator AT IDLE. If you don't load it down with an old-fashioned roll out load tester like a VAT40, you'll never know how many AMPS your alternator can really put out. These little handheld testers they use now cannot tell you that. The number of AMPS available is critical to amplifier output.

Great amp!

This amp puts out a good bit of power. For my setup I have. I've had crunch amps in the past so I already knew what I was getting. So if you want an amp that puts out power and for a good price..this is the one i would recommend.

Decent

Is it putting out 1800 probably not but it did blow out one of my 800watt maxx 450 rms subs out with the gain set low so it does have some power.
