I heard good and bad stories about Optima batteries. Is there an alternative? My system won't be too big. One 4x75 amp and one 1x300 amp.

 

I just got an optima and it works great. I got 500/1 and a 300/4 jl amps

 

Gel cell batteries are about the best you can get for stereo/deep cycle applications. There are several brands out there...I ran stinger in my car.

 

i have 2 optima yellow tops, and i love them. im running 2 1800watt amps and one 600watt amp and they hold up great....... make sure u buy the correct one though there are a bunch of different sizes and models. if u have a advanced auto parts near u i found that they have the best price $149.99.

the d34/78-950 should be perfect.
