ok this is going to be my next setup. brand new Fi Q 12 in a custom ported box tuned to around 32hz. it's going to be powered by a new hifonics brx2000.1d. setting it to 15000rms with a dmm. I drive a saturn vue 2003. 125 amp alt I believe. if I do the big three and add an extra battery to the back, will that be enough or will I have to have a HO alternator? my last system was 2 12 AQs on a fosgate p1000bd and it made my lights dim pretty good but I didn't have the big three or an extra battery. any advice is much appreciated!
