I'm new to the forum. I'm currently rebuilding an S10 ext can. I'm running hertz mids and highs, 2 sundown sa 10s, and hifonics amps. I'm wanting to go with 12s or 15s though. maybe either the nightshade or something from addictive audio. I don't think the 10s will be enough. I've also gotta find some better amps for this build.
