Jl Audio 250/1 Car Audio Amplifier Logo
Posted on Jul 02, 2009

Output problem I am using this amplifier to power a pioneer champion series 12 inch subwoofer. It has 2 4 ohm voice coils, wired in parallel to get a 2 ohm load. I followed the users manual to set the voltage at 22,4 volts, which gives 250 watts at 2 ohms, and my sub was barely responding, so i turned on the gain to get between 40 and 50 volts, the equivalent of 1000 watts out of the 250/1 amp, and the subwoofer handeled it, but the amp was heating too much, and the input wasnt precisely reproduced. Should i consider a more powerful amp for my sub given that my subwoofer is rated at 400 W RMS? Can this amplifier handle a pioneer TS-W307D4 or TS-308D4 pioneer subwoofer (12 inch double voice coil 400 W rms) or should i go for a more powerful one???

    I was talking about rms power, since power=voltage*current
    the problem is with the jl amp's normal power i cant seem to get the pioneer sub moving...any help?
