    500w-600w

    Im looking for suggestions on amp for my alpine 1223d. I would like a SQ stereo amp that can do500w 2ohms bridged or a SQ mono amp that can do 500w at 4 ohms im not against buying oldschool amps.

    Just under 500W at 2 ohms bridged, but look at the Boston Acoustics GT2125. Sonic has a good deal on them

    Otherwise, you could get 900w at 2 ohms bridged on a Boston GT2200

    Just checked the specs and I was selling the 2125 short. Bridged at 2 ohms and 14V, you'd be seeing 600W by CEA specs. At 4 ohms, 400W bridged. For $110, that's a good deal.

    I do not fully understand the question. You subwoofer can be wired either for 1ohm or 4ohm impedance. Why do you need 2ohm bridged?

    If I was you, I would buy a PPI P600.2. This is a tiny two channel Class D amplifier. In bridged mode, you get 600watts RMS power, with minimum 4ohm impedance. You get 4ohm impedance when you wire the voice coils of 1223d in series.

    Re: 500w-600w

    Good catch. OP, do you have a pair of these or a single one? If it's a pair, then zako's right and you'll need to look at that power given at 4 ohms or 1 ohm.

    Re: 500w-600w

    when i run it on a bridged amp at 4ohms doesnt it change it to 2ohms since its bridged? I only have 1 sub. I havent messed with car stereos for 15 years i thought it used to be that way atleast.

    Impedence will be determined by how you wire the subwoofer, has nothing to do with it being bridged or not.. I believe your subwoofer has dual 2 ohm voice coils so it can be wired to 4 ohms or 1 ohm. You are likely going to want to wire it to 4 ohms.
    If you are unsure what impedence you are wired at you can check it by using a multimeter on the speaker wire coming from the sub.
