I'm planning to get a series of LEDs for my truck. Underbody, Interior, Under door handles. Plus I already have a 350 watt (RMS) amp with a 410 watt (RMS) subwoofer. I'm wondering if I'll need a capacitor or possibly an extra battery? Any other help associated with LEDs would be appreciated, such as, mounting, wiring, hooking up to stereo (colormorphics style).
