Question: 11 October 2015

Car: Peugeot 307 - <2005 -

Im having dificulties to setting right amount of frequency on this thing. Can you explain me how to do it by ear, do not have knowladge how to use multimeter..


frequency will really depend on the woofer and how much you want to to play, most 12" subwoofers we would set to around 100hz but you could set it slightly less or slightly more dependent on the range that you want the subwoofer to play

Hi I need a opinion on this amplifier. I have 2 12" subs Alpine type r - 300 watts rms @ 2 ohms Rockford fosgate - 500 watts rms @ 2 ohm


Hi, Thanks for your question, you can not run 2 subs of different power ratings, this amp runs 300W RMS @ 4 OHM & 500W @ 2 OHM. you would need 2 matching subs.
