i was wondering if anyone knew the cheapest place to buy an optima blue or yellow top battery...and also, whats the difference between the blue and yellow top and which is better if so?? thanx

 

What is.........NOT AUTOZONE or ADVANCED AUTO. (Try NTB or a car audio shop). BTW you mean between red and yellow (blue is marine) red is for normal applications (cheaper) and yellow is for deep cycle applications (such as sounds systems with enough bass to please a lady)

 

why do u want blue????
get the red top. yellow top is for long current draw and deep cycling. Red top should be ample for your needs.
costco is good. only $99.

got my boys at costco for $99 too... no more dimming lights when bass hits.

 

oops i meant red top then i guess...i was confusing the red with the blue...i knew one was for marine, but wasnt sure which...thanks for the help guys
