Check the sticky at the top of this section.
I'm personally running 2 Kinetik HC 1800's but there's cheaper ways to get the same/similar results...I'm just a name brand *****, and I like it like that.

 

where is this vent at?

and you just gave me a really good idea on how to seal up the big 3 hole by the pedals

 

lol u should see how fucked up mine looks. i got a piece of LLP. cut a star out of it. pushed the wires thru and duct taped it all together. works pretty well IMO

 

my guess is your stock battery is fucked

 

Which Memphis Amp?

 

i just ordered 3 spl tiles hopefully i can get it all sealed up with that...i wanted to stay away from LLP cuz i didnt want to have to deal with spray adhesive and wanted to check out the spl tiles anyways

 

spl tiles are nice dude... but cutting them sucks. lol i spay adhesive doesnt really keep LLP up thou. too heavy

 

they must be thick as ****

damn maybe its not a good idea to seal the hole with them...idk where else id put them though damp pro has done a pretty good job

 

lol u can try but its like sheet metal. lol when i tried cutting it with a blade it just made an indention. needed to like pierce it each time or use scissors

 

sub'd. i was about to do this with my system but after reading this i got majorly confused for some reason. mostly the part where Cefaln452 said about fusing it. anyway, clearing that up would definitely help seeing im trading systems with my cousin. hes got a 1000w amp hooked up to two 10" kickers. that'll definitely drain my car of all the power needed.

 

i have a dual battery set up now and it works great no problems yet but i will keep everyone posted...

 

Can you kinda simplify all the connections you made? Like:

pos+ of first battery to this, and this to this, etc., etc.,

include fuses and if you used an isolator cuz i really dont wanna screw this up lol

 

If your going to do dual batteries on a stock alternator, I would recommend a switching system to you only charge 1 battery at a time.
If not, the life of your alt will be decreased.

 

how would that work?

 

The better question is how does it drain thel life of the alternator? Does everybody understand that the alternator puts out X voltage, and X amps, that doesnt change. Having two batteries dosent change that fact. The only problem with multiple batteries is that they will discharge each other over time. Even that is not really a problem in a car that you drive on a regular basis.

For the person who asked, the wiring is simple:

Stock battery:
Positive:
-Factory 4ga from front of car
-Factory 8ga from wherever
-4ga over to second battery positive
Negative:
-Factory 4gq ground
-4ga over to second battery negative

Second battery:
Positive:
-4ga from stock battery
-4ga to amp distrobution block
Negative:
-4ga from stock battery
-4ga to ground lug terminal

Technicly I had to switch the grounds on mine because I didnt cut the factory ground wire and I couldnt get it to bend around to the new terminals, but you get the idea. A fuse or breaker would go in line with the positive wire between the two batteries.

You know, thats seriously how i thought it would be but it just seemed too simple. Also someone else tossed in something about fusing it and a battery isolator. Other than that, you pretty much cleared it up for me immensely lol thanks sean

 

I'm planning on doing this myself very soon and I was wondering if I do fuse it what size fuse does it need to be?

The best thing to do is to upgrade your alternator.
Or ask any MECP certified audio installer.

 

right i was going to upgrade my alternator. i got a list of numbers to call for alternator places to get pricing for rewinding them to increase the amperage output. unless theres an easier/better way that i can do it myself or something that im not aware of.

 

hmm only the coupes have the battery in the trunk correct? because my sedan has it up front..

 

Well wasnt that just a marvel of a technical explination I think I will just listen to the elctical engineers I know and work with. I am not saying, or have ever said that upgrading the alternator is not a good way to go, but having 2 batteries will have no negative effect on the alternator.

damn ill just order a square of damp pro, seal it up and have some left over...what should i do with these tiles? im thinking about just throwing them on the trunk lid on top of my damp pro...
