    Hey guys, just bought this sub:

    http://www.sonicelectronix.com/item_43403_Rockford-Fosgate-P3S-1X12.html

    My question is, can I use this amp to power it? Some have told me I can't, some told me if I run the wires in series instead of parallel, I can. The sub is wired internally to produce a 1ohm load. I was told since it is dual voice coil, I can open it up, run the wires in series and my amp should be okay. Here is the specs on my amp. It's not stable at 1ohm so I need advice.

    Pioneer GM-5500T with specs:


    Power Specifications - Full Range Channels
    RMS power @ 4 ohms 125 watts x 2 channels
    RMS Power @ 2 ohms 190 watts x 2 channels
    RMS Power @ 1 ohm Not Stable
    Bridged RMS Power 400 watts x 1 channels
    Peak Power Output 820 watts x 1 channels
    Amplifier Specifications
    Amplifier Class AB
    Number of Channels 2
    Total Peak Power Output 820 watts
    Total RMS Power Output 400 watts
    Maximum Input Gauge Size 4 AWG

    id run a decent class D mono block honestly.........it will power the sub CLEANLY without overheating.

    u always wanna have more power than ur driver can handle, and just use ur head and know when to stop cranking the volume so u dont distort it....especially with a 12, they are more prone to distort due to them being less rigid than some smaller subs due to surface area.

    But will it be okay if I do it? My amp generates 400w at 4ohms bridged. If I wire the sub like this

    It will create a 4ohm load, correct? Since the sub is a dual voice coil. If this can be done, I'd rather save some money.

    ..stay tuned
    Not sure if Im missing something but the sub you linked is wired for 1 ohm.

    "st make sure you pair it with a 1-ohm stable amplifier. "

    It's a dual 2 ohm sub. I opened up the box, they had it wired to 1 ohm.
