How much is the battery going to last ?

Question

I have a vw jetta 2002. I hooked up 2 kicker comps 15 with an amp1600w how much is the battery going to last with those? The battery has like an 1 year. And I don t have no cap.

Answer 1

If you never turn them on, probably several years

Answer 2

Get a cap or you are going fry your alternator,  hook up a second battery and you'll be safe AND get better sound.

Answer 3

I would definitely invest in a cap if I were you, just for your alternators sake, but not really too much in need of the second battery yet, but in the future I would suggest a higher end battery (optima yellow or red top maybe?) but if you want to see how good your battery is, take it to autozone and have them test it to c if its still good, if it is then you should be ok until you decide to make an upgrade on it, they also do alternator tests so you can see how good your alt is performing, just a thought...
