I am running a 2000 watt panasonic amp power 2 12" subs in my xterra. these wires aren't as thick as a 4 gauge set should be...but they still get the job done. the only problem I really had was that the fuse holder was WAY to big for the wire. It was probably a holder for a 1/0 gauge wire, not a 4...but good deal for the money!
