[QUOTE="HardofWhoring, post: 8832623, member: 674149"] Your alternator is not effecting that in any way. All your alternator does is recharge your battery. If your stereo draws more than your alternator can recharge, it will only draw from the battery (the storage bank). Your alternator will just recharge it as best it's capable of. If you added an AGM battery in the new setup vehicle, then that battery is capable of everything you need. Your problem is not in the alternator or battery. You could use a larger alt, but that's not what is restricting your setup. not sure if that's 400 +500+1200 = 2100 / 14.4v = 145.83 amps /.85 amp efficiency = 171 amp draw for those 3. You should be good with a 200 amp alt. If you have your head lights, AC, engine running, brake lights, something charging off the cig lighters, and you have a heavy bass track, while below 1200 such as sitting in traffic for a half hour or more without picking it up, you would probably need to turn it down to let your alt catch you back up. Anything other than that highly compromised situation, and you are probably good. What is different about the new setup? Unless you used the same head unit, did you reset your gains? [/QUOTE]
