Great AMP

This amp is great for the price. It's the best amp I have owned but, it is quite big. I use it with 2 pioneer and The bass is amazing!

KILLER BASS AMP!!!

This was my very first time using an Infinity amp other than the one that came in my car as the factory sound system. I must say you cannot go wrong with this brand!!! The Infinity 1211A IS A MONSTER BASS AMP THIS THING PUSHES SUBS LIKE THEY ARE PAPERWEIGHTS. I have this Class D Infinity 1211A Subwoofer amp pushes two 15" Alpine Type R dual 2 ohm version wired series parallel to get a 2 ohm mono load and I am afraid to even turn the bass boost on!! These subs are moving so much with gain at only a quarter way up, low pass set at 80 hz, (DBO set at 20 hz and 0 bass boost)!!! Reminds me alot of my old kicker 1500.1 at half the price, BUT SAME POWER & PERFORMANCE!!!

PROS: VERY EFFICIENT, UNDERRATED, POWERFUL, LOUD, AND PUSHES ANY SUBS TO THE LIMIT!!

CONS: DOESN'T HAVE ANY!!!

great amp

This amp is great for the price. I have owned audiobahn and alpine amps. I will admit I am an Infinity guy, but this amp pushes my solo baric L7 to the limits. The bass is amazing, and the quality is good. no humming whatsoever

Get it while you can.

For the money you can't beat the power/performance. It's only real downfall is the 12 db per octive crossover and the fact you cannot find anywhere to buy the wired remote. Just be carefull you don't blow your subs with this. There aren't many subwoofers that can take this much power.

AMP IS GREAT FOR PRICE

i have two L5's hooked up with this amp..i have them in the back of a 03 tahoe with a custom box from tweeters (2 cu. ft. each.) and its great ..my whole car shakes...a screw from my roof already fell....i have not yet "broke them in yet" and they are still loud..DEF BUY THIS AMP

Why doesnt everyone get one of these

Oh my woofers this is a very powerful amp that doesnt draw much power. It is powering my 2 Infinty 12.1 perfects at a 2 Ohm load. Gains set extremely low and deck sub setting is down -2db. I wish they would package the sub level control with it as noone seems to have it.
