[How to run the Big 3 from the backseat....]

i dont think imma have too much to need an extra battery just yet... 4 alpine type r 12's and only a pdx 1.1000 so far, looking for something 2500 rms at 2 ohms.... but i do think my alt is on its way out so that will be getting upgraded when the money is right

What exactly is a Big 3 upgrade?

[How to run the Big 3 from the backseat....]

Okay, i have a 99 cadillac sls... my battery is underneath the rear passanger side seat... exactly how am i supposed to run the big 3 upgrade like this... I'm in the process of adding 4 12" type r's, right now i only have a pdx1.1000 to power them but soon im gonna be running about 2500 rms and adding a kinetic battery to the setup... the Big 3 is something that HAS TO BE DONE... just wondering the easiest way to go about doing this...
