Ok so i have a 10" JL w3v3 4ohm driver and a cheapo pioneer amp( i know i know moneys tight) So i hooked this all in my 05 ranger with a Kenwood Excelon deck. I have 2ga welding wire for ALL hot and cold connections. I did the big 3 except for the engine ground for Now. I tossed my cap out as it didnt help and read alot of bad ju ju about them. I get dimming light as do most on Hard bass hits whenthe amp is at +6db's and the deck is at 5 to 15db's. I want to know if i should invest in a second battery (xs power or kinetick) or swap the stock battery out for a better one?? Otherwise i thought about just getting a H/O alternator.? I dont wanna spend a fortune i want to still be able to Replace that amp.!!!!! Thanks alot guys!
