hye poeple...noobish queestion...

i want to install 2 subs...with 21 amps..one sub using each amp..i want both ams to be attached to one car deck and one battery...how will the setup look?...

also how do you use 2 batteriess in a car?...

these questions im wondering...future reference...

 

I'm assuming you mean 2 not 21 amps. Basically you will have a power wire from the battery (fused) to to your battery in the back, then from that battery you will run power and ground to your amps. Make sure to run a positive and negative from each battery, fusing each end of the power. There will then be a remote wire (18awg) from the decks remote turn on to the amps in the back, and 1 RCA cable from the deck to each amp.

 

i don't get it..do you have any diagrams showing hwo i can do such thing....

 

 

Green thing is deck, green wire is remote turn on, and blue is RCA's.

 

i dont know how much clearer the picture can be to your question man. If you use only one battery then just take out part of the picture on the bottom left side.

 

whats the black line connecting two battries and the amp?..isn't there only one wire going from battery to the amp?...
whats the thing with 2 lines in the middle?
ot is it to connect both battries together?

 

Dude, for the safety of yourself, go to a shop.

 

obvicly...but i want to learn it...so if it dose get like messed up one day..i won't have to spend 100 dollers jsut to get a small wire fixed you knw?..

 

The problem is that will get messed up today any you will have to take it to a shop and pay like 500 bucks to get everything fixed. all because it got screwed up in the first place. Do you have any friends that know car audio that can show u the basics?
