I want to wire some LED strips to the bass speakers in my car so that they will light up to the music. I reason that you cant wire the lights in parallel with the speaker because the lights can blow with too much volume. I also read that it will trash the sound quality. ?
Anyway, my plan is to use a relay on the positive side of the speaker to be a switch for the lights. This way, when the speakers get power, the switch in the relay will close, and the lights can get power as a separate system, that way sound quality is unaffected. Does this plan sound good?

I've seen people just tie them in to the speaker wires on cheap amps and they seem to work fine ..
