Guys, I just picked up a ed nine.2x and a nine.4. I taked to the factory and they said a single run of 4 gauge will be ok. Then I can go 8 gauge to each amp. I already have 16 feet of soundquest 4 ga power and ground. I was searching on the net and found a 2 ga install kit on millionbuy.com its a power ack. one for like 35 bucks. Would it be better to get that kit than to run my 4 ga and split it off to 8 gauge.
