    Default Help With Amp Please.

    Ok i just baught a pionner mono amp 800watts, and i have 2 15 inch subs 1200watt peak (i know low peak watts, and the amp may be small but thats all i could afford atm)

    I was just wondering if i could connect both of them subs up to the amp, because the subs are 4ohm independance, and **** knows what the amp can handle lol.

    Few Q's
    What could i peak the subs at with that amp?
    Will it even run both lol?
    Do i just put both wires straight into the amp or do i goto wire them parralell or something

    Thankyou for this Team420.

    Firstly you need to find out the RMS handling of the subs, not peak. Once you do that i can advise you about it.
    Basically with your amp, it puts out 800w x1 at 2Ohms, You will have to wire the subs to in in parallel ie. connect the (+) on the amp to both of the (+) on the subs and the same with the (-).
    You can only do this if the subs can take 400w each (which they should but find out first)

    Continuous Power Output - Watts RMS:
    (20 ~ 240kHz into 4 ohms) 250W x 1 (0.5%)
    (20 ~ 240kHz into 2 ohms) 360W x 1 (0.8%)

    Don't have to worry about feeding 400W into each sub, the amp won't produce that much!

    Not having a go here, I'm just interested, why do people still quote Max ratings rather than RMS?

    Cause i know **** all about car audio lol,
    They are only cheap boss audio 15's and i couldnt find the RMS (Model Number Ba-152)

    Anyways cheers so far guys, anything is appreciated.

    ^^^I was talking specifically about the manufacturers. I guess it must be for all the little rice burners out there so that with one or two subs they can claim to have a 2000W system for less than $500 LOL.

    Manufacturers quote big max ratings because it sells... People who don't know alot think that the power rating on a product means how loud it will go, and most people want loud music from their upgraded stereo.

    mouce... When you first got into car audio, did you look at max ratings? I did... I bought my first Pioneer head unit over Kenwood because the Pioneer was 45Wx4 and the Kenwood was 40Wx4. It stupid now that I know a little about car audio, but it defintely swayed me towards Pioneer for the higher power output.

    To be honest having gotten into car audio later than most (I'm 22 now) I'd studied enough electrical theory to know that max ratings were a waste of time. And that for amps/speakers/head units it was the RMS that mattered the most.

    But I can see that it would be an easy trap to fall into.
