    Wiring amp to woofer

    Ok, i ve got a Power Acoustik system.
    I got a TS 1440. Its a 2 channel amp, Mono RMS= 720, 1440 watts max, RMS= 300x2CH at 4 ohm, RMS= 360x2CH at 2 ohm.
    I've also got a Fubr 12 which has 700 RMS, 1800 max. This woofer has dual 2 ohm voice coils.
    (I only have have and need to wire one woofer.)
    Should I...
    Wire each voice coil to each channel of the amp separetly thus having 2 ohms going into each channel.
    OR
    Wire it in series to create a 4 ohm load and bridge it on my amp?

    Which option (if at all) would give me better sound quality? be louder? be more safe for both the amp and the woofer?
    Also, I paid a total of $300 for these 2 components and a ported box... is that good?

    Do you by any chance, drive a heavily modded truck? Lowered... with a NES in it?

    Ok. Your name and question just sounded very familiar to someone who was recently on here.

    you don't wanna wire it up with the voice coils on different channels, too risky in messing up the sub, you're better off running the sub either parrallel (1ohm) or series(4ohm), however, that measurement of 720watts rms is most likely for 2ohms, check if it can handle 1ohm, if not, see what the rms is at 4ohms briged.

    For right now I'd say you're best off wiring it in parallel with the amp briged, good luck

    Thanx Dennis, my amp is 2 ohm stable so no-can-do on the 1 ohm load. and an employee from this web site i know told me that the 720 RMS are for a 4 ohm load bridged, but is that possible?

    **** thats prob. right, I've actually never briged an amp yet, always just used monoblocks, but yeah I'd just double check the manual/website.

    And make sure that you tune it right....

    sqrt (720*4) = 53.6656315 is the best the amp can do
    sqrt (700*4) = 52.9150262 is the best your sub should see

    So you'll be looking for 52.9150262Volts AC out of the amp using a lets say 100hz test tone with your Head Unit turned as loud as you'll be putting it

    lol, ok... to tune your sub... you don't want it to have any more watts then it should...

    On every amp there is a "gain" setting, this is what sets how much the amplifier amplifies the signal from the head unit...

    Lets say you have a sony Head Unit that puts out 2volts on its rca cables (the cables that you plug into your amp that carry the signal), but you want your subs to run at 52V which if you figure out the math equals 700watts... you need to then set your amplifier to amplify that signal from 2 volts to 52 V...

    This is why the gain control is not a volume control, for if you had a nicer head unit that had 5V to the RCA's going to your amp, then your amp wouldn't have to work so hard to get to 52V... meaning less room for distortion...

    This is how an amp works...

    Basically 700watts is a lot, so you may not want it at that much, fine, thats by ear, but if you want to max out and just go balls to the wall, make sure you get a volt meter and measure the power coming out of the amp, and that it is at 52volts AC (Alternating Current), no more for this will probably burn out your amp, thusforth destroying your sub with it...

    Sorry for the novel, but you may still not really understand what I'm getting at... may just have to sleep on it/google...
