Excellent Amplifier A++++++ buy

Well , all i can say is that i am using the RF 40001 bd to power 2 FI BTl 18 inch subs in a ported box and it is all out devastation . Literally shaking everything in my expedition .The bad thing is , i haven't even damped my truck ,which i will have to do because amplifier is just killing everything in it. Listen to me when i say this , i will never buy another amp again unless its Rockford Fosgate. Definitely Street Motivated Devastation...............Jose

Powerful Amp

I love this amp its a real powerhouse and its made in the USA. The only con i have is be ready to upgrade your alternator and add a couple of batteries.

OMG THIS THING IS AMAZING

i got to hear one of these in a friends truck. He had it pushing 2 Orion HCCA 15.2's and wired at 1 ohm and it was the loudest system that i have ever heard. would definitely recommend, and it is a great price.

amazingly amazing

this amp is a MOSTERRR. my bestfriend got tired of me bumpin aroud all the time, and decided to kick up his game. he found an older (2005 ??) model 18" SOLO X. he bought this amp online, im not sure from here or not, and it pushes that thing like nothing else. of course if you buy it you would have to upgrade the big 3(alt, batt., and wires), or just get extra batteries for the back.

WOW!

this amp is insane! It puts out a ton of power and is from a great company too. It is underrated though as it puts out about 4500 watts instead of 4000. You have to be serious about your bass if you want this amp as it requires a h.o. alternator and a new battery or two. Also make sure your subs can handle the power. This amp is huge too, at 33" long it will be sure to fill up your trunk.

Best amp ever! Well built!

I give this amp two thumbs up! I'm pushing two Kicker Solo X 2ohm dvc subs with one T40001bd. Both subs are wired for 2ohms. I have a 300amp high output alternator, yellow optima battery, and Tsunami 40 farad cap. Both subs are hitting hard.

Real Power

I still have this amp I couldn't tell you how old it is and it's still practically blows the windows out of my van

Wow is insane

This amp gives a ton of power also demands a ton of power. With 1/0 G power and ground inputs. I have 2 runs of 1/0 G 4 yellow top batteries one batcap 800 in the back at the amp and 200 alt. It is well under rated the box said 4000 watts Rms. But when I open the box this big 33 inch amps birth sheet 5200 watts RMS. So I put the amp to the test. I put it on to digital design 9515G. They are 6000 watt Each. 3000 RMS each. This amp is pushing them like a champ. I Blow 160.4 with this T40001 I is the loudest thing I every heard in my life. If you are looking for an powerful amp this is it You can't go wrong.
