    Ok, I'm new to car audio but I picked up 2 12" infinity's and I also have box that I'm putting in my car. Now I have no idea what kind of amp I need. I just want a setup where the amp just pushes my 2 subs. Someone please reccomend me a sub in the $250-$300 range or even lower. Also the subs are Infinity Reference 1220w and its a seales box.

    Thanks, Tom

    are they single or dual voice coil and what is the impedance of the subs (how many ohms)?

    2 if the amp will only be used for your subs. If each voice coil on your sub is 4 Ω, then you can series wire the voice coils of each sub together, and paralell them into the amp, meaning you bridge the amp. Your amp will see a 4 Ω load. So choose an amp that matches the RMS power of your subs, i.e. if each sub can handle 300 watts RMS, then you want an amp that will put out 600 watts RMS when bridged @ 4 Ω

    If you paralell wire your voice coils and both subs, your amp will see a 1 Ω load.

    Ω = ohm

    most of the reference series subs were single voice coil.

    the 1220W included
