i had a alpine mrp-f250 for my 4 channel amp before and this bad boy makes my excelon speakers scream.i didn't buy it here but wish i had would have saved 20 bucks.anyway to the point this amp makes my alpine amp seem like a joke.was considering the new kenwood amps instead of this one.but i don't have any regrets at all.this amp is insane.i swear my bass response on my speakers tripled . I'm not kidding.very nice fosgate.American made too.fosgate should go back to the American made speakers also.their new speakers are a joke compared to the old school fosgate.audiophiles know what i am talking about.buy this amp; you wont regret it.
