Default Wiring a Subwoofer

Guys

From what I understand you need a 8 or 10 gauge wire directly connected to the battery to operate an Infinity Basslink powered subwoofer amplifier.

I have an aftermarket receiver which has subwoofer outputs which I already prewired but when I looked at the engine firewall/bulkhead I couldn't see a quick or easy way to run a wire from the battery to the interior. I hate to drill through the firewall and install a grommet.

Also I will need a switched 12V which is also a requirement for the amplifier (otherwise it will always be on). I plan to tap from the driver or passenger side electric motor seats, unless someone else has a better suggestion

Thanks in advance

I just wired my fog lights yesterday. the easiest way I found was to run a wire at the front door jamb through the "A" pillar under the weatherstrip. i drilled a small hole through the body under the dash. [IMG][/IMG]

once it is in under the dash you can hide it under the carpet, or inside weather strip all the way back to wherever you need it

as far as your remote wire goes you need only .5 volts. you can just tap something related to your radio so that way whenever you turn on your radio it comes on. but if your running an aftermarket stereo you will have bright blue wire in the loom and that is always your remote wire. you can pm me if you have any stereo questions

sorry so many posts but you know to never run your power and remote wire near your coax cables. you can get an extremely obnoxious interference.

Dear suzukiam967m: Thanks for the pics! That looks straightforward. Have a few questions: Why is the wire red on the 3rd picture and black on the first two? Did you put some sort of black protection on the wire in lieu of a grommet? What size of wire was that? Also what does "pm" me mean? (Sorry I'm new to the forum)

Thank you again for the help offer!

Sincerely, Al G

Yes it is black because I use shrink tubing. so when I run a wire through a firewall or where it will be exposed to the elements, I always put two or three layers of shrink tube. it is probably overkill, but my electronics never give any problem. I was telling another forum member yesterday when I was 16 I put a stereo in with crimp connectors, and when I would hit a speed bump or a really rough road the radio would cut out. I tore it all out and properly soldered and shrink tubed all my connection. I've wired boats, hotrods, custom bikes and about everything else 12volt. and never had any problems. it takes a couple more minutes, but it is a professional job.

As far as what gauge wire I used, I'm not sure i just used one of my big rolls I've had forever. if you don't have your remote wire you might just consider one of the cheap walmart amp wiring kits, the have everything you need and the connectors and right gauge wires.

For running the wire....

Open the hood and look down in the drivers side engine bay toward the rear. There is a rubber grommet that either a cable or wires run through (can't remember which). The other side comes out below the fuse panel... pull the knee panel down, below the steering wheel and you will see it.

You need to use a ratcheting crimper with the correct size die for the lugs. Then this won't happen.

yeah.. ok... well when I was 16 i was crimping things together with my dads needle nose.. you missed the point.. the point is, if you solder and shrink tube your connectors, you never have to worry about them. I'm sure there are some excellent crimp connectors out there... that wasn't the point.
