So… A 4000 watt peak power amp for less than $140(price includes next day shipping). Just get it. I bought this amp because my 2 expensive Orion XTR15001’s blew. I bought this as a quick replacement amp/backup so i wouldn’t be without bass for two long weeks. I had to send my amps in for repairs. Man, this thing has power for sure. My setup is: 6 Kicker CVR 12’s dual 4ohms, wired down to 1.5 ohms, a huge custom vented box with 3 chambers 2-2-2(subs facing up/not a wall), I was somehow able to connect 0 guage wires, two Optima batteries, and some other goodies. All in a 3rd Gen Exploder. Comparing this amp to other high brand amps like Kicker, Orion, JL, Rockford, etc… this thing is awesome for the price. This amp basically forces power to your subs. The bad part is that it lacks clarity. Something that I truly look for when buying an amp. I feel like i have 4 15’s in an old school boxed Chevy without dyno… It’s kind of sloppy. If your system doesn’t normally hit the highs, this amp will force it out of them. Possibly pushing your subs to the edge. Or if your subs don’t hit the lows, yeah you’ll get it. Just be careful not to over do it. I’ll end with this, the amp is capable of blowing all of my subs if I wanted it to. If you have some L7’s, JL’s, RE’s, or even some Orion’s, it’ll BANG! If anything, just buy it for a spare like I did. Oh, connecting 0 guage was almost impossible. 4 guage is proper. If you do have 0 guage like i do, just strip some of the wiring and be sure none of the wires cross over! “Use electric tape.” Enjoy this amp as much as I do! Don’t mess with the sub-sonic gain if you don’t need to. Peace my fellow bass heads!
