Uhm, probably not the best way to approach the question lol. 10 gauge is basically worthless in my opinion. Even 8 gauge is a baddd idea. Do yourself a HUGE favor, and rip that crap OUT! It wouldnt handle 1 solobaric s7 let alone 2. (btw 2, is 1 too many in my opinion as well.) You need to rewire with atleaaast a 4 gauge, but probably a 2 or better if you are going to run 2 solobaric L7s.

If your willing to spend hundreds on 2 L7s... spend the money on the 2 gauge wires.
