hey guys so my maxima if sitting for a long weekend maybe 3-7 days will die out of no where like dead no charge at all. let me give u guys some insight on my car it has a 2 month old Optima red top battery i got it retested to see if i got a bad apple they said it is excellent but jsut needed a charge, the alternator was tested and they said it was A+ lol but it dies when it sits for a while now here comes the issues probably i have 2 tvs, with this wierd thing under my seat made by kenwood idk if its a amp or what it looks like one but doesnt really seem to be one, i have 3 8inch subs with 2 amps in the back of the trunk, i also have a aftermarket navi headunit made by kenwood, it has a connection from the batter to charge the past owners phone i want to take it out but i am to lazy to rip off my dash, it has 3 turbo guages which i guess can take energy, and it also has a aftermarket clifford alarm and electric tien dampener system, but when i drive the car everyday it is fine it starts up like a beast thank you optima lol but yea idk what i can do i did alot of prior research but nothing to make me make a move. i was thinking of just taking out the system. or just removing the amp wire or whatever its called from the battery terminal for now so i dont have it dying on me all the time cause it does sit around quite often cause i am not driving the maxima yet. what are my options if i dont want to take out my system i believe that is the culprit of my constant power draw what do you guys think? will their always be a constant draw if i want to keep my sound system? i heard about finding out where the draw is comming from but im pretty sure the biggest draw is the amplifiers for my sound system.

o yea forgot to add the past owner pulled out soo many fuses for some reason i guess beacuse they were unneeded since he had so many upgrades idk

here are some pictures of my system and battery

Have you tested to see how much of a draw you have. Pull one fuse at a time until the draw drops to .1A.

Your first problem is using a battery designed for starting over the yellow top which is designed for a high amp load combined with letting it sit will destroy it. Are you still using the OEM alt? That is also a **** ton of wiring grouped together there, you dont have any interference?

thanks for your insight honestly i dont know too much about the car at the moment im pretty sure its a stock altenator i do know the past owner went through 2 duralast batteries in 2 to 3 year span cause he had a warranty on the last battery which got me back 50 bucks, i just see all these crazy wires running around. im not sure what i want to do now like if i want to keep my system and im daily driving it i can leave it and be fine but i just dont like the idea of it dying all the time i heard capacitors help but arent worth the money as an extra car battery is stronger and can do more but i dont want a extra 30-50 pounds in my trunk i already slowing my car down with that system in my car. i heard of switches that can turn off your amp from inside the car but i have no idea how to do so.

If you want to keep the system the way it is the easiest solution would be to add an auxiliary battery, kinetic makes a good one. You do not need another full sized battery. I would just minimize the system and the wiring. Likely the alt can not keep up the charge on the battery while powering all of those accessories. Can not be sure without testing the draw. Do something or else you will get to your car, especially now that it is cold, and it will not start. All of that wiring is just insane to me. That is what a distribution block is for.

yea it does sound crazy i dont like it but i got a good deal on the car so im not complaining i can just strip the audio and electronics i dont want to buy a auxilary battery i just bought the red top battery for 160 on sale which is a good deal for a optima. i will probably take out the amp for the sub and the sub leave the amp thats for the speakers and take out the miscellaneous **** that is not needed one by one and i will try to test for the draw when it better outside for now i might just unplug the amp and not the amp wire you think a wire with nothin connected to it but jsut the battery will still be a pull?

hey guys just an update so i found mad wiring under the trunk it was nuts! it really made me nervous that i was going to have to pull my whole system and just use speakers from walmart or soemthign with built in amps so i dont have a strong pull, but then i look under my hood for a while and in the pic with the tip of my filter showing that says hi-amp has a button to disconnect the system from being able to be used! so im thinking when i do that it doesnt draw power i didnt check yet cause i was short on time so ima check it out tommorow or monday! i have hope! lol i think i might take out my tvs tho cause i dont use them i been had tvs in my TSX for over a year and i never use it in their either sometimes my friend uses it in the back when i have more then one passenger so i feel like theres no need, then i can take out that thing under my seat, possibly buy stock head rest dismantle it and sell it. (also i wanted to get reupholstery kit from leatherseats.com in the future but the tv headrest just make me nervous to do so unmatching colors ew )
