There is alot of threads about batteries, so here is what i did (not that it matters) I switched from 2 Deka 12 volt deep cycle to 2 vmax charge tanks. I switched last year, and haven't had a problem yet! I got tired of checking water levels and having to charge the batteries every other weekend. When I went to the new batteries (vmax) the length of play time has at least trippled! The stereo actually got louder I believe as a direct result of mass amount of power. I am running 3000 watts of power all Alpine PDX amps so low draw but still a alot of power consumption. The batteries are a little pricey, but is minimal compaired to my stereo. I guess I look at it like doing a full frame off restoration on a muscle car and cinching up and leaving the engine untouched with 120k miles leaking oil, and smoking like crazy!
