    Re: headlights dimming

    Yeah.. you can.. I dont know what size battery you use though. Look up what group size your battery is then look for good dry batteries in that size

    Or you could always wire up whatever size you want in your trunk

    Re: headlights dimming

    When you did big 3 did you add it to stock wiring or remove the stock wiring

    Your alternator likely has alot to do with it

    Adding a second battery can always help too.. and its super easy to do, plus, the benefits of having dual batteries is awesome (jump your car from either side, have a backup battery in your trunk to throw in your friends dead car)

    Try adding a second battery. Your alt should be more fine. Your electrical can't keep up with the amperage being discharged for whatever reason.

    Your oreilly agm is not deep cycle I believe. Maybe return that for a deep cycle (yellow top, etc)

    What amp are you running, and at what ohm?

    Double check your wiring and make sure you arent running it at .25 or .5 accidently (or ideally get a DMM to check)

    Triple check your grounds. A bad ground will def cause this. Is your amp grounded to your batterys negative?

    Re: headlights dimming

    Battery and amp share the same grounding point but amp is not grounded to battery post if that makes any difference and amp is seeing 2.1 ohms at terminals

    ---------- Post added at 04:47 PM ---------- Previous post was at 04:46 PM ----------
