[QUOTE="airman, post: 8349021, member: 658784"] I have a Alpine PDX F9 4ch amp. 600watts rms running 2 Hertz HSK 165XL and 2 HCX 165 6.5 Speakers and a PDX M6 mono amp, 600watts rms powering 2 JL Audio 10W6v3-D4 subwoofers for a total of 1200 watts rms. I want to upgrade my mono amp to a JL Audio HD1200/1 mono amp which is 1200 watts rms which would be a perfect match for my subwoofers. I have a Toyota RAV4 V6 with a 150 amp alternator and a Optima yellowtop battery under the hood, in the fuse box in the engine compartment, the alternator is fused with an 140 amp fuse. I don't think that 150 amps is enough run 1800 watts rms total power however I don't have the money right now to upgrade to a H/O alternator so I was thinking of installing a second battery fused near where my amps are, perhaps just enough battery for a 1200 watts mono amp like the HD1200/1 to replace the capacitor that I have there now. would that work or not? I plan to use 1/0 gauge OFC battery cable. I'm mot sure about doing a big 3 because the nearby Toyota dealership I called to ask for info on whether a big 3 upgrade would work told me that it might damage the vehicle electronics so I'm not so sure about doing it now however, could I get away cheaper with a 2nd battery to power a more powerful mono amplifier?
