i searched but it didn't help...

how do you run a wire from the battery?

and then how do you install the subs and amp

 

Use a hole in the firewall. If you're asking these question i'd recommend you have someone do it for you. Search our Audio & security section for more info. There's alot more to it than just wiring up a "sub & amp".

 

u'll see a black plug w/ wires going through it on the firewall on the driver side. Take a sharp flat head screwdriver adn push it on the plug (about half way b/w the center and the edge of the plug) as if u were trying to tear through it. Push it in really hard and u'll make a hole to run ur power wire through.

and yeah, if u ask a question like how to hook the amp and the sub,
like ^he said, then u really need to get someone else to do it for you.

 

it took all day but i have a working subwoofer, but my friend told me something about bridging? whats that, he said it would sound even louder

 

If you are asking these types of questions, you should really learn as much as you can about car audio before messing around with it. An improper installation could:

1. sound very bad
2. cause damage to your equipment
3. start an electrical fire (I've seen it happen before)

I would suggest reading up at caraudioforum (dot) com and similar sites. If you're still feeling a bit lost, the best thing to do is have a professional or someone knowledgeable in this area do the work for you.

 

oh man, first timer for car audio install. alright follow along. On driver side FAR UP the dash, there is a large black grommet that u can run your power wire through. Run your power cable along the panels that hold ur carpet in place (trim @ door) run wires all the way back to ur trunk for your amp. Now from your head unit, run a remote TURN ON LEAD (usaully blue with white stripe) and run that with a set of RCA cables to the back OPPOSITE SIDE OF YOUR POWER WIRE !!! now as for a ground, Use an existing bolt or make ur own hole to screw down a ground cable. Make sure the grounding are is clean of paint or any residue. A best ground shows 0ohms on a volt meter. Make ur necessary connections. Now, depending on ur amp, it really depends how many ohms it can take. if its a 2 channel to bridge, Connect the Postive of Channel 1, and Negative on channel 2. Some amps will use 2 postives on each channel. Double check with ur spec sheet. As for fusing the 12volt wire, Measure 5 inches from the amp cable from the batter, Fuse it accordingly, and your set. Enjoy some music.
