New Battery? powering down amp..

[chillmatic]

Ok so heres the deal.. i got a 98 dx civic.. i have two jl 12 w3v3.. two days ago i washed my car and somehow water got in my trunk and my amp and blew it up.. it was an audiobahn a8002t.. since that amp fried i decided to replace all my wire with jl audio 4 gauge wire.. today i purchased a polk momo c5001 amp.. 875 peak and 500 rms .. hooked everything up no touching wires or anything.. and the amp hits for a minute then just powers on and off.. i dont think i have a short anywhere or anything so my guess is i need a new battery? but im not sure ive had this same system for a while .. even the old w3v2s and never had a problem.. but i am also running fog lights .. halos .. and side mirrors with blinkers off my battery as well.. and if youve had an ek you kno how small the stock batteries are.. so any opinions?

Use a Digital Multi-Metter to check your battery voltage. When your car is off, it should be around 12v and when you turn on your engine it should be around 14v.

You said it only turns on for a few minutes. Does it turn back on when you restart the system again or is it completely dead?

You can have as much accessory you want, when you start your car, it does not run on the battery any more, it runs on the alternator. The battery is only use to start your car and to run anything else when the car is off.

Thats not quite accurate, stock alternators are only designed to recharge the battery under a limited load, if the power being pull from the battery is greater then the alternator can return, the battery will slowly lose its charge(power), and can burn up the alternator. The older the battery the greater the possibility for the battery to lose its charge.
