New member Username: KartoonPost Number: 1 Registered: Nov-10 | Hey fellas/ladies, I have a 2002 Acura RSX Type S with either a 90 or 95 amp alternator. I'm planning on powering an older Hifonics Atlas AS12SQD4(rated at 900w RMS) (http://www.sonicelectronix.com/pictu...&picture_id=-1) with a Hifonics BRZ1200.1D amp. The amp is rated at 900w RMS at 2ohms. I will also have a Cadence FXC2D 2 Farad/12 Volt Stiffening capacitor. From my battery to the amp, I will be running 4awg cable. My question is, will I be fine with the stock alternator & battery, or will I need to upgrade either or both? Also, for the time being, the stock Bose head unit will remain. I plan on getting a PAC SOEM-4 Universal 4-channel line output converter to connect the amp for rt now (http://www.crutchfield.com/App/Produ...7SOEM4&tp=3486). Thnx in advance for your thgts and help. Kartoon |

The new head unit will eventually have its own crossover to use for a 3-way setup when you're ready. |
