If i have a 4 channel 2000 watt amp, can i use 1600 watt wires if i only have 2 subs hooked up to it?
Yes, you will be fine. 4 gauge power wire is sufficient for a couple of reasons, the primary one being that most of the companies that are boasting 2000 watts for a 4 channel amp are off brand "web-retail only" companies, and they severely over rate the power output of their amplifiers. Secondly the supposed 2000 watts is peak power and not rms power. Peak power means how much power that amp can put out during absolue climax of the music or during a tone burst. RMS power is how much that amp will put out continously to your speakers or in this case, your subs. If you look at the spec sheet of that amp, in all actuallity you're probably only getting 200-300 watts rms even bridged.
On a side note, if you really want to push your subs hard, you might want to consider getting a mono block or "class d" amplifier and use that 4 channel amp to push your surround speakers. Class d/mono block amps are specifically designed to push subwoofers and will give you the most efficient power out and the best heat dissipation to withstand the output required to drive subwoofers. You'll get better bass and also more adjustability to tweak the sound levels coming out of your subs. Hope that helps.
