    Rockford Fosgate BD1000A1

    Any of you guys have experience with this amp?

    A co-worker bought this amp for his subs this week. He's been running a Memphis Audio mono amp @ 1 ohm powering two DVC 4 ohm subs. I think the Memphis amp is rated 1000w RMS @ 1 ohm. Anyway, all of the specs I've found online show that the BD1000A1 is 2 ohm stable, but they don't mention 1 ohm stability. Is this amp 1 ohm stable, or did he goof up with this purchase? He doesn't exactly understand wiring config. and I don't think he did his homework before buying this amp. If it isn't 1 ohm stable, then he's probably taking a step backwards as far as power is concerned. A local car audio shop claimed that amp is capable of 3000w RMS, which sounds ridiculous to me.

    I don't think it's in their current lineup. He bought it used and I think he said it was several years old.

    I just did a search for it earlier today and looked at reviews and specs from other websites.

    that amp is about a year or 2 old. i used to have a 1001bd. it is not 1 ohm stable. do not run it at 1 ohm. i ran mine at 1 ohm and it fried instantly. it's a great amp you are planning to run it 2 ohm. it also doesn't produce 3000 watts. mine was benched at 1100 watts rms.

    The amp could be older than that, is it an old power 1000a1? I use to have one... great amp. I never ran mine as 1 ohm, and no RF doesn't recommend running it at one 1ohm. He might be fine, he might not. If he does it, I'd at least give the amp some extra cooling ... I'd stick with what ice said though. As for 3000 watts , if its the old power bd1000a1 I bet it does a good amount more than 1100 at 14.4.

    Re: Rockford Fosgate BD1000A1

    My friend has 4 -12" RF HX^2's with 2 bd1000.1's and WOWWW, im pretty sure they are 1 ohm stable (newer ones)...but he claimed he had them running at 1/2 ohm???...i dunno, true or not, I was very impressed with this amp. I also hear an Eclipse ***. 15" with a bd1500.1, and the amp fried at 3/4 gain...BUTTTT it sounded incredible....that alone is why I am looking to get 2 of these subs. Was louder (or Sounded louder) than my 2 12" L7's at 900 watts each.

    This amp is fully 1ohm stable i used to have 3 of those monsters

    now i have 4 1000bd running 3 ma audio 6ohm dvc on each amp that's 12 subs
    the power of this amp is amazing maybe not 3000rms but at least 1300rms@1ohm@12.5v.

    trust me those amps are not 1 ohm stable.

    Yeah, he said it's the older Power Series BD1000A1. I'm gonna recommend he get new subs. If he keeps the DVC 4 ohm subs he has, he'll have to run this amp at 4 ohms and won't be anywhere near its full potential. The specs I've read show that this amp only puts out about 750w RMS at 4 ohms, so he's actually downgraded from his Memphis as far as power is concerned.
