Get a kicker 4 guage wiring kit and you should set. If you plan on upgrading anytime soon I would just go ahead and get a kicker pkd1 off ebay for like 87 shipped I think great amp kit. If neither of those work for you try www.knukonceptz.com
The different size gauges are for different power requirements 4 guage is good up to 1500 watts if you have quality 4 guage wiring anything above you should get 1/0 guage etc. Like I said you will be good with 4 guage but if you plan on upgrading I would just go ahead and get the 0 guage kit now and be done with it. Its a very nice kit I just bought one comes with distribution blocks and everything in case your running more than 1 amp
Yea get it off ebay its great wire dude def for the price. If that's not enough strands you can check out the knukonceptz kollosus wire which is always out of stock. But I think you would be best to get the kicker pkd1 off ebay
You should never have your amp "maxed out" and you always have to set your gains go to 12volt.com and read up about gain setting if you don't think you can do it take it to your local car audio place thts what I do bcuz I'm sure u would hate 2 fry your stuff u worked hard to buy bcuz of a stupid error tht u make. Key rule to learn don't use your gain as a volume control and always keep the bass boost off.
