I have 2 sundown x 15s. would a salt 4 be enough to maximize those subs or should i get a salt 6?. electrical is very very strong.

They can handle the 6 if the rest of the install is done right... 🔊⬆️🌕

What gauge size holes are the battery terminal inputs?

The SALT-4 uses a set of 0/1 gauge inputs

Will the Salt 4 overpower two U15's wired to 1 ohm load?

We've seen people beat up on a single U-12 with a SALT-4. The pair of 15's on one amp would actually be a pretty perfect match!
