Help with car amplifier wiring?

Basically I have a 3000watt amp, and I need to buy the right wires. Would I still manage to get the full power out of the amplifier with 1000w speaker wiring kit or do I need to buy a 3000w speaker wiring kit?If so, where is the difference with the higher wattage wiring kits.Thanks

3000w amps are rare and expensive. Is that peak power or rms? Can you provide the brand/model? If it's ACTUALLY 3000w rms you need a high output electrical system with a custom alternator and probably a 2nd battery, and at a MINIMUM you need a GOOD quality 1/0 awg wiring kit. On the other hand - if this is 3000w peak the actual power (rms) could be as low as a few hundred watts. Amps this size will run w/o a problem with most stock electrical systems. A good 4 awg wiring kit would probably be more than adequate. Many lower level brands use bogus peak ratings to make their equipment appear to be more powerful than it actually is. Wiring is based simply on the thickness of the copper. Some of the cheap brands are less than honest about the size of their wiring. They get around advertising regulations by only using the word gage or gauge, not the wire standard AWG. If the wire you use is too small it will have excessive voltage drop so the amp will not be able to produce the power it would otherwise. More importantly, in extreme cases if the wire isn't fused properly it can get hot, melt the insulation off and become a fire hazard.
