i have a cheap walmart battery in my car and when i have my lights on the subs dont hit as hard n when it does knock the lights dim off when bass is being played n back bright when it cuts off what battery should i get if im on a strict budget
How strict is the budget? Do you want to put this battery up front or can you put it in the trunk? (the second question will determine what size/group battery you need)
A Kinetik HC1800 would be a good battery, if you have the space. You haven't said how much space you have for a battery or what kind of car it's going into. You can find them on Ebay for $179.99 plus shipping and they have a lot more current storage than any Optima has.
