Subwoofer in a Grand Prix 2003

**Dooty** · 06-13-2011

Hi guys, Im new on this forum and i have a simple question for anyone that is REALLY good in Grand Prix (2003).

Today i installed my aftermarket radio and everything went fine.

My next step is installing my subwoofer. To start off, im not a beginner at installing subwoofers and all the audio stuff. My question is : The power cable for my Amp needs to be plugged on the battery and i cant find the dam hole that goes from inside the car to under the hood if u guys know what i mean by that. The hole the is usually near the pedals (gas, break) near the fuses. I checked today, and tried to find the hole but i couldnt and i dont feel like making a hole.

Thx for ur answers in advance !

It's on the passenger side, under the glovebox area.
Which makes sense since our batteries are on the passenger side.

With that said you'll want to run the other wires on the driver side then.

There should be a hole right behind the engine more towards where the heater hoses go into the car.

Mine is an 03 as well, I removed the washer fluid reservoir and there is a grommet on the passenger side that will come in behind the glove box. Blah...^^ ninjad.

I got lucky with mine, I already had an amp wire that had been cut off near the firewall on the inside that I was too lazy to remove, so I taped my new one to that and pulled it through.

Mine goes through my fender, I was to lazy to drill a hole and besides its coming out soon and getting replaced with some 4 gauge wire.

Running a 4 gauge wire though the passenger side was a hell of a lot easier than running a 12 gauge vac line through the driver side.

It's not a hole. On my 03, it was a big square rubber grommet. Had to use a big ol screw driver to puncture it.
