[QUOTE="wew lad, post: 8658910, member: 665412"] Optima has been low quality for 5+ years now. They live on the reputation they used to have and clearly it works because you thought it was worth the premium lol If the battery is relatively new and functioning properly then no it won't help to add a large battery as you'll still drop below 13v. Going from 14-15v to below 13v is the dimming you see. I doubt you want to throw a ton more money at it so check the voltages when it dims (it'll work during the day too you just won't see the dimming). Report back with your lowest voltage at the alternator/front battery, and also the amplifier input terminals. Your gain probably is clipped, which is fine to [I]some[/I] extent but if it stops getting louder with each click of the volume you need to turn it down. Without adding even more alternator output, a huge bank of batteries (or lithiums), the only thing I've found to help is adding a single bank of ultracaps. Not the big single cap, I mean legitimate ultracaps. After you report back with the voltage you find I'll give you a recommendation [/QUOTE]
