can you? yes. Is it as effective? questionable.energumeno wrote:1. Is it possible to place the capacitor before a fused distribution block? (Some manufacturers say yes, some others say never put a fuse between the capacitor and the amp.)
you want the capacitor to be as electrically close to the amplifier as possible, so between the fuse block and the amp is ideal. It's also generally advised to use 1 farad of capacitance for every kilowatt of power the amp is rated for, so sharing a cap between amps isn't the best idea. Better to dedicate caps to each amp ideally.
doesn't matter. common ground anyway as long as you use sufficient gauge wire to handle the current draw, and have a solid ground connection. Your car's chassis is equal to 4AWG wire anyway due to spot welds that hold the unibody together, so if you need more than 4AWG wire for the system, you're better off running 0AWG wire directly to the battery negative terminal anyhow, and using a grounding distribution block.2. Should I wire the ground of the capacitor to the same grounding point of the amps or should i ground it to a different point in my car's chassis? (Again some manufacturers say to ground at a different point, some others suggest at the same point to avoid grounding loops.)
What do you think?
