ok i dont even have a subwoofer in yet and my battery is already dying on me
i have four amplifiers and two electronic crossovers installed but they're all relatively low power - two 300W class AB amps for treble and two 600W class D amps for midrange. there is no bass in the system yet.
every 2 weeks or so i would try to start the car and it would be dead. i thought that ain't so bad so i just bought new booster cables (longer and thicker) to make jump starting the car less of a hassle ...
problem is now its dead every time i try to start it ... so i need a new game plan lol.
im thinking of putting a remote controlled relay/switch in the trunk to disconnect everything in the trunk from 12V power when i leave the car ... problem is i dont know if such switches exist ? i would need to connect it to my zero gauge power cable and have it rated at least 250 amp (because thats the fuse rating on the subwoofer amp that i already bought).
alternatively i could buy a pair of batteries and put them in the trunk ... but im not sure if this would even work since my weak 90 amp alternator would probably not be able to charge them up and i don't have the money right now to upgrade the alternator.
any ideas what i could do ? im at the point where i can't even use the car because of this mess ...
PS: my battery is about a year old but i it has been heavily abused. that is it has been run down completely about 10 times in that year.
