[QUOTE="hispls, post: 8574454, member: 614752"] So ignoring the risk to your amp and the lost power, what do you suppose happens when you reverse polarity on the relay? How do you suppose the relay will hang trying to energize 20-80 times per second? Assuming this was even a good idea the correct component to act as a fast switch is a semiconductor (transistor), not something with actual moving parts. Seriously, they make kits designed to make lights pulse with the beat, or if you want to have lights come on when the sub amp is on just use the rem wire from your head unit on a relay, or simpler still use a toggle switch.
