Im looking for a 4 guage amp kit to wire to my JBL BP1200.1 amp and subs and i was wondering if getting a Scosche amp kit from Wal-mart would make any difference than getting a more expensive one online. Would name brand wires make the subs hit harder? Would the name brand wires last longer? Is Scosche less durable and would you recommend buying a 4 guage Scosche amp kit?
The only really limiting part of that kit would be the RCA cables. If you already have good RCA's go for it. The more expensive 4 gauge usually just has more strands and is more flexible. The insulation might also be somewhat thicker but if you use a rubber grommet in the firewall(and you should regardless) its no big deal. 4 gauge is pretty much 4 gauge when it comes to current handling and I believe that Scosche stuff is "oxygen free" so corrosion shouldn't be a problem.
I'm actually thinking of purchasing that exact kit to upgrade my alternator wires. Its cheaper than getting the 4 gauge by the foot and has some other neat goodies inside for later use.
