I currently drive a 2013 Dodge Avenger R/T with the 3.6liter V6 and I have 2 JL 13w7's, 2 HD1200/1's, Alpine 137bt HU, with Alpine 200watt power pack running JL C2 61/2's in front and C2 6x9's in rear and stock 31/2's in my dash and I also have a audio 1000 watt capable battery in my trunk wired in with the factory batt. As of right now I'm only running 1 sub and 1 amp and I wandering what kind of electrical upgrades I would need to run both sets for 2600watts that's 2 amps and the power pack together. I'm gonna do the big 3 and add another 1000 watt capable battery, do you guys think this would be enough, or would I need a high output alternator as well. I pretty sure the pentestar engine has a 160amp alternator stock. Thanks for any replies. And I know you can't give me perfect answers I'm just looking for ballpark here before I proceed with putting the other sub and amp in. Ow and the subs are in sealed prowedge JL factory boxes.
