I have a 2008 Jeep Grand Cherokee, I used to have two 12" Orion Cobalt and a 1000 watt amp in there with a 4 gauge wiring kit, now i want to get two 12" L5 Kickers that have a 2400 Watt Total Power Handling (1200 Watt Each Sub), and a RMS Power of 1200 Watts Total (600 Watt Each Sub). So my question is, can I use the same wiring kit I had or should I buy an 8 gauge wiring kit, what power amp should I get, and also would I need an extra battery to power these or no????
Thank you
