I have 2 15" subs and my amp is 1500W rms. If I use them for a while, my battery voltage drops and my air bag light comes on. I was thinking about buying a HO alternator but they are very expensive and out of my budget. I was looking online and was thinking about upgrading to a high capacity battery. If I bought like lets say a Optima redtop, will it help out a lot more so I dont have to go through the cost of buying a HO alternator? Thanks in advance
