LOL! If you think wires are gonna deteriorate after a few months, you've been rolling up aluminum foil and using that as your wire. I've had temporary setups with lamp cord as speaker wire and I've used nice Stinger 12ga. The lamp cord didn't deteriorate after a few months. Any wire remotely designed for car audio nowadays will usually hold for years and years to come - the wires are usually laid and aren't tampered with or exposed to the elements so there's no reason they'd deteriorate at an accelerated pace. If you think there's gonna be any noticeable difference between the WalMart kit and the expensive kits at Best Buy, you've been hanging around salesmen too much and bought into marketing hype.

And yes, the 6.5s thing was an assumption on my part, but that's why I put "IF" he has components, which people usually do in the front for decent setups.
