ummm......

clips easily, whining noise, i highly doubt that this amp pushes as much power as it is rated for

This is the biggest piece of garbage that I have ever bought. The biggest mistake I ever made was to buy any product of Rockford. This amp has been nothing but problems, you cant run this thing more than 1/2 gain or else it will clip and wreck your subs as it did mine

lots of power... power... and more power small. GREAT FOR DEEP BASS.

gets a little warm when run hard for a couple of hours. needs a cap. and a battery upgrade.

when i was shopping around for amps i wasn't looking for a bd1000 i was looking for a 700 or 750s but i'm glad i found the bd1000. these amp hits hard like a mothaf*** if u want a amp the hits hard for a good price u should get a rockfordfosgate bd1000

So far so good. Never had a problem with a Fosgate. Tons of power. The 24db crossover is great. Running it to Power Wedge 12W7 with a Voodoo cap bank. The combination is not so loud but extremely clean. Someone mentioned that whining noise when you power up? I noticed it too and it stops away after it warms up. A HVAC specialist friend of mine said it is the thermal protection circuits - makes sense I guess. Will probably never need that circuit anyhow, ran for 2 hours crankin'-never even got warm (3 ohm).

tons and tons of power, it just doesnt give up. SQ is a little above average, nothing to brag about, but the power makes up for it.

draws a ton of power from batery, i have a 1 farad cap and my headlights still dim when the bass hit, during the summer you could fry an egg on it after bumpin it for an hour or two, but that problem is easily fixed with cooling fans on your amp rack. These are minor and do not deter from the amps ability

First of all that idiot above doesnt know what hes talking about, he probly didnt even get the power class, i worked at best buy and all they sell is the punch class, which is CHEAP. Dumbass. ANY WAYS ITS A LOT OF BANG FOR YOUR BUCK!. I wasnt a big RF fan before this amp either. I am pushing 2 Mccauley 10''s. never heard of em? check www.mccauley.com. They are huge, 17 pound magnets with single 4 inch voice coils. they can handle a load of power and this amp is runnin at 50%!! I am exxtremely impressed with the power. I would recommend putting cooling fans on it otherwise you can fry an egg on it. The sound quality is a little above average but nothing spectacular. If you need power at a good price this amp will rock your world. Oh by the way it comes with a test sheet, my came out at 1105 watts. slightly above 1000....

Not too big, tons of power(!!!), looks awesome, sounds awesome, end caps protect your wiring, subsonic filter, low-pass crossover. The best sub amp for what I paid!

Emits a high-pitched whining noise form within the amp. You can''t hear it unless you''re close, and according to Rockford Fosgate, it won''t affect performance.

Got this amp at a steal for $600 Can. (worth about $1100), and man, I haven''t regretted it! This amp produces loads of power, even more than my 1000watt dvcs can handle. Trick is, you need the install done right, or all you''ll have is problems, from what I''ve heard. This amp can pound for a long time without getting hot, or even warm! I have not had a problem yet, and it sounds great!

No problems, generates over 1000W, powerful

not too many come to mind...... should have used a 4gage wire instead of 8?

Great performance, very very loud, have it hooked up to 2 Rockford HE2, in a firebird, pushing 110db. Great performance, nice look, extreme power and fits in my car....(hardest part)

high power to subs(when u get it to work)

EVERYTHING, this amp did nothin but piss me off

the reason i used it less than a month was b/c i took it back after a week. it probably wasnt the amp''s fault, but probably the people at Best Buy who know absolutely NOTHING about amp installation or sound quality

lots of power and punch, extremely clear,no distortion, well over 150 db''s in a small sealed box

none that i know of

this is the best amp i''ve ever owned period!!!!! 1100 watts hooked up to two Rockford Fosgate POWER 12''2 with the dual 4" voice coils...this thing does some serious pounding!!!
