ok my set up consisted of 1 2000 watt amp with 2 12"kenwood subs and a tsunami digital cap.all works well excepts that after about a month my battary goes dead. i thought it was a bad battery and replaced it with a new one but a month later again dead. check alternator and good again. batt terminals good as well. the one thing i know is wrong with the set up is my wores are from an old 300watt amp i had, so i never upgraded the wires could this be causeing the problem? or is the stock alternator just not enough for all that?
power slowly being drained somewhere and if you're constantly bumping the hell out of your system and not allowing it to recharge, that'd definitely be another cause...
try getting a 40 dollar charger from walmart and have it charge overnight, every night, otherwise learn to give your eardrums and your car's electrical system a rest.
Oh yeah and caps don't do anything to help your electrical system.
btw is that 2000 watts max or rms? what brand/model amps and SW's?

caps reduce the stress on your alternator - other than that +1 ^

ur cap drained ur battery.....when ur car was off, did u notice ur cap always on? blinking or somethin?, if so u probably have a bad cap and should switch it out.
if thats not the case then i agree with PO57, cuz the battery IS just a limited supply of electrical power, just like if u leave ur lights on when ur at school or work, or overnight it would drain ur battery.

ok but if my system is off at night....why is it still draining? the cap reads about 13.8 when i shut it off, but the next moring if i can get it to start its at like 9.5 ish.
so for some reason i have something pulling power when it shuts off, and if it shuts off and i jump start it im good for the rest of the day, (guessing the alternator is filling it back up) and it dose this weather or not im thumping it. the cap is turning off after about 30sec.
its a 2000watt lanzar vibe amp.

Edited because these mistakes drive me nuts...
Your system may be technically "off" but SOMETHING in the car is pulling some sort of power, whether it be a light, neon, amp, whatever? For your remote turn on leads for your amp(s) did you just wire it directly to the battery? or did you connect it to a "switched" source? (kills the connection when the car/headunit is off)
At 9.5 volts, you're ruining your battery terribly. At that point you might have to replace both the alternator and your battery at the same time. UPGRADE ALL YOUR WIRING. Please don't tell me you're using stock wiring, this is a big mistake. Upgrade grounds especially on the alt and battery.
I really doubt the cap has to do with anything unless he somehow wired it up extremely bad.
Lanzar vibe? ........ rofl. Then you're really only pulling maybe like 1000 watts, not 2000... :lol:

its a brand new optima yellow top and the alternator was replaced by the deal when i got it less than a year ago, so neather of them should be it, its gotta be something with the system cause i have gone a few days without the system in the car and havent had any problems. so im sure its the apm or the cap, just gotta figure out why im pulling power after i turn off the car. thinking maybe i need bigger guage wires? my POS is only and 8guage. so im thinking that could be it?

you are just not reading or ur really stupid...
SOMETHING IS KEEPING YOUR AMP/STEREO TURNED ON
Bigger wire is not the solution
putting the amps in a different spot will not cure it
And if you drained that battery three or four times down to 9.5 volts it is dead as well. no matter how new it is. you cant kill lead acid batteries like that even yellow tops.
Eh it doesn't even have to be his stereo, he probably has heated seats and they're stuck on? (just an example) it could be anything. But the fact that he keeps asking the same question repeatedly even after we answer it.... thats just stupid.:roll:

thats cause no one is answering my question, nothing is on in my car cause its been over a week without the system in the car and no problems power wise, the batt is fine alt is fine, so its something with the amp, cap, or wires, and i understand that something is pulling power from the batt after i shut it off (i'm not stupid) what im trying to figure out is what and why so i can correct it.
"SOMETHING IS KEEPING YOUR AMP/STEREO TURNED ON"
^^^^^^^^^^------thats what i wanna know, what could be causeing this!!!!
could the cap be bad and just miss reading, could the fact that i'm only useing 8guage wire insted of 2guage be starving the amp and so the amp keeps pulling after its turned off?
btw the remote wire for the amp is to the remote wire on the back of the radio not to the batt.
i have instaled systems b4, just never had this problem, which is why im trying to figure out what is causeing it.
Its his system....
Oh, i never read that... :oops:
I concede in defeat :P
As far as Dsmdreamer, you gotta look for it dude, we dont have ready access to your car like you do. I'd recommend taking it to a(n) (audio) shop or a dude who knows what he's doing.

could it be that his cap settings are off??
TpaS13 had a similiar problem, thats why i put my word in, we installed and charged his cap, but somethin about the settings were off. Bcuz of that everytime he turned his car off, the cap would remain flashin, this was after he played the system, the first few times it happened i noticed the cap turned off after a while, then the next times he would always tell me it wouldnt shut off...and it was draining his battery bcuz it would remain on all night....Bcuz of that he switched the cap out, and no more problems, the cap stays on for a little bit, then goes into standby mode or wutever when the cars off.....
Other than draining ur battery everytime bass hit, i dont think the amp has much 2 do with it, so u should definitly get the cap checked out before u go into assumptions with the wires.
Chances are maybe Toby is listening in, i dont know if he is cuz he would've posted a suggestion by now, but maybe u could stop by TJElite and they could check it for u, thers other places but i would trust him the most, bcuz if he couldnt help u, then he has more opinions 2 clarify everything.

there is a matching pot on the cap that matches up the voltage on the cap to the actual voltage in the car - if its too low or too high the cap will remain on thinking the car is on.
you could use a DMM to verify the cap's meter matches the actual voltage.

everything matches, the other thing is its not like killing it in one night, the problem gets progressivly worse.
for example today i put the system back in. i turn it off at 14 volts. tomarrow when i turn it on it will show 13.5, then the day after 13, then 12.5 etc etc etc, untill the batt gets so week that it will no longer start.
now remember this is as im useing the car, so the alternator should recharge the battary, but its not, when im driveing or car is on i have 14volts, but as soon as i shut it off the cap starts pulling, till about 13.5ish, then shuts off, next day wake up turn on car, cap shows 12 volts, turn on car 14volts, turn off car, jumps back down to 12, go to turn on next day 11.5 volts.
and leaving it on an overnight charger is not gonna happen cause im in an apt. complex, and im not dragging it up 4 floors everynight.
im gonna try running the system without the cap for the next few days, i can tell its pulling a lot cause my headlights dim out alot with the bass, but if the alternator runs it fine then i know its the cap, if it still kills the batt, im thinking upgradeing to a stronger alt?
I hate to say it dude but take your entire system out. Put in each thing one by one, testing for a day, until you find the problem. Make sure you have good wires/grounds/everything. Make sure that things aren't staying lit up/on whatever. Make sure you have switched sources, and that your relay(s) aren't broken and staying permanently on.
You aren't going to get anywhere constantly whining to us on the forums, this is about the most surefire way of doing this other than leaving everything hooked up and inspecting each unit individually.
