I’m using this cap with a 500w amp, so it’s probably way more than I actually need. That being said, even when the volume is up and the sub is hitting hard, my lights don’t dim at all. The cap has been excellent. The digital display doesn’t work, but that’s not a big deal to me because it’s just one less light attracting thieves. The brackets are a bit flimsy, so be careful when installing it.
