Im making a custom box for them. I need to know what i need to set that up in my 98 GMC Yukon. Do i need to replace the alternator? Do I need to get a high end battery. Do i need to run new wires. I have 4 gauge wire right now running a lightning audio 12 and a fosgate p2, but im getting rid of those. I already got a capacitor its 5 farads. Im running a 1400 watt amp. Any advice? I know a little about car audio, but not enough. D
