Im going to argue with this. Neither of the 08s my family owns with lights on have hovered around mid 13's. Always closer to mid 12's. Both are 08 sport 2.4s. Also both when you let off the gas the lights and will dip down if the air is on and the lights are on which means its for that amount of time falling to most like 10-11volts before the alternator catches it.
remember the alternator on these cars isnt that big and many items pull a pretty decent current. But even at that the amp is rated at 14.4 volts but not getting it. Which means the amp is not putting out the watts its rated at. Also do remember its a 12 volt charging system.
Which means its nominal output is 12 volts. It might get a bit above that but not that much.

Well you could be right but I've had a digital voltage gauge installed in my car for the past 6 months that tells me differently, the only reason I may dobut myself is because it's reading the voltage my amp gets, but I'm pretty sure the voltage will be the same throughout the whole car. I also have 2 deep cycle batteries and 0g throughout the car so that may be the reason

Are you running anything to seperate the batteries from the charging system when the batteries have a full charge? You could also be running your alternator harder. But yes those batteries would affect your end results. and 0 gauge? how much power are you pushing? Im a fan of the kinetic batteries or the BatCap setup you can buy (pretty neat lil thing its a battery and a cap built together).

you might want to get something that disconnects your batteries from your charging system (forget what its called brainfart..) But your most likely maxing your alternator out which also could be a reason for the higher than average voltage. that could lead to your alternator dying faster than normal. Have you had a clamp put on your system to see what your actual #s are? Since you live in st.louis Mach 1 audio is washington can do it. Theres another guy name Josh Landau off 44 in the valley park area who does amazing yet expensive installs and he might be able to test it out as well to see your actual #s.

Why would I want to disconnect my batteries from the alt...then they wouldn't be charged and what do you mean by clamp? Total rms or voltage/amps? Rms with the 4 ch amp is like 2900ish

If you do a clamp test on your system it will measure ACTUAL wattage your amps are putting out. Its not the rated watts of your system.
my buddy has an mmats amp thats rated at 2000 watts. Between wiring and his charging system it actually puts out slightly under 1200 watts. If he upped his charging system and switched to better wiring hed get a lot closer to the 2000. But yes if he claimed rated wattage on his setup it would be around 3000 as well.

ive been out of car audio for a while. It only disconnects them for a bit so the alternator isnt running at 100% the whole time.

for a true 2000rms using anything smaller than 0g is retarded

Been a while since I talked to him and he had it all hidden away in a storage compartment in his envoy. Will have to ask him next time I talk to him. It was an mmats 2000 watt amp with 2 treo 12's. It managed 140.1db but thats not bad in a big suv with 2 12's. But he didnt know the resonance frequency or anything it was his first ever soundoff. But still not too bad.

though, i'd throw a wager in that if u put down the back seats, u'll notice an increase in bump.
at least i do. only time i'd do such a thing though is in the summer.

Didn't bother reading everything but...
You need a CAPACITOR!!!! Bad. You will get much much much better bass response with a cap and you also won't ruin the alternator/battery in your car. Do it. Do it now.
