Decent sized stereo and underdrive pulley on the crank and no overdrive on the alt. Occasionally play the system with the truck off at the beach or while detailing. Which one should I get? And possibly the PN for it.

 

Red top. It's cheaper and will handle anything you can throw at it.

 

id get a optima yellowtop

if it was me id get it at a local parts store around here autozone carries them

 

Costco is cheaper, I will be getting it from there, going to go look tomorrow I guess.

 

we dont have one of those around here

 

We didnt till recently, they carry them in stock and I believe the Yellows were like 115.

 

I paid 180 for mine like 3 years ago.

 

wow- pick one up for me and ship it to me... it'd be cheaper than me buying one around here!

 

Yellow top is a deep cycle, so if you plan on letting it discharge (extended playing with the engine off) often, do that. Red top is a cranking battery, it won't take well to discharging and recharging. I've had a Yellow top in my truck for almost 3 years and it's been great. That's what I would recommend. We had a Red top in my mom's Suburban for a year or two and had problems with it after it discharged and recharged a few times.

 

Yellow it is, Ill check them out tomorrow after work if I get a chance.
