i got a 500 amp wiring kit on my 600watt amp since i got it(is it safe using a lower watage wiring kit for a higher watt amp?). i just bought a 750watt wiring kit. will i get more sound with the 750watt wiring kit?

 

What gauge is it and what amp make and model. Do not use the max wattage ratings to figure stuff out.

 

is your amp 600w RMS or peak? is the wiring kit for 600w RMS or Peak? If you have a 600w peak wiring kit with a 600w RMS amp, that is no good (as sonic would say). As most people on this forum will say, run 0awg! (or minimum of 4awg IMO, and do the big 3, makes a big difference depending on what your vehicle wiring is stock.)
