How much could i power with this

16 volt batteries wouldn't make sense on a factory alternator. to charge a battery. You have to be above its resting charge. 12 volt batteries charge at 12.5-15ish

a 16v would need to be getting 16.5-18ish from your alternator.

your alternator is doing 14.4-15.2 most likely.

correct me if I am wrong anyone? that is just my understanding.

i guess after looking up your battery it says that it is 12v and 16v capable. but remember. on your stock alt. the batteries voltage will be the same as your alternators. because that is what is charging it.

someone can give you a better answer than me.

But IMO.

If you plan on running your system on batteries. It's not a matter of how many watts you can run. It's how much time can you play your music before you have to turn it down and let the alternator charge the batteries back up. If you plan on running that AQ2200 of yours (i think that is what you have)

Your better off upgrading the alternator first. I believe the alternator is the most important electrical upgrade after bigger wire of course. Your alternator is what chargers your batteries. Your batteries should only be used to disperse the energy to your amp faster and as a reserve so your alternator doesn't get overworked.
