Ok, so before i start, i just wanna say i know im goanna get a LOT of crap for this.
anyways, i have a kinetik khc800 batt charging from the cigarette lighter. i have my amp (SS tx1.200d) running off of it. my sub is an SPLX-152hf. so the reason i have it ran this way is because the car is not mine until i graduate so i had to find a way to run a system without "modifying" the car. so, i did it this way.
my question is, how can i get better voltage with the way i am doing it. my voltage never drops below 12.15. should i get more/better batts? what can i do.
