Porsche Installation tips pg 8

The above picture shows the amplifier's 8 gauge wire run through the trunk area. In this 993 I've run it through a rubber grommet that already exists near the clutch pedal on the floor. If you have a factory CD changer, follow that cable's path for a great route for wire. 964's don't usually have a good grommet in this area. You can drill a hole and mount your own rubber or snap grommet in place, or feed the power wire from inside the car up through a big rubber grommet under the dash behind the stereo. I use a long plastic "fish" to snake the wire through. I'll usually lube the fish and wire with Windex to help it "slip" through rubber grommets. Your wire will now pop up into the cowl area, where there is a plastic panel along the rear of the trunk. Look under there from the passenger side, then route the wire (covered in plastic flex loom, ideally) into the black steel tray below your fuse panel. (Fuse panel is easily loosened and lifted by removing one allen bolt and one thumbscrew.) To then route the wire through the bottom of the fuse tray you can use an existing grommet if one exists, or drill and grommet your own hole. Watch where you drill, you have a plastic gas tank under part of that tray! Look from the front of the car to make sure you're clear before you drill, then simply route the wire around the passenger side of the trunk to the battery's positive terminal, installing the fuseholder as close to the battery as 3" or so, if possible.

The above picture shows the amplifier's 8 gauge power wire, now covered in split loom tubing, fuse holder in place and connected to the positive battery terminal. (Make sure you have the other ended connected already!) More zip ties make it neat and secure.

This picture shows my hand and fine Casio G-Shock watch in action. I'm using a long plastic zip tie as a fish to work the speaker wire for the driver's side subwoofer under the carpet to connect it to the amplifier. I use Windex to help lube things up and melt the adhesive holding the carpet down. I find it's easier if I actually run this wire under the rubber mat, rather than between the carpet and rubber carpet pad/mat. I'll make one pass up one side, then down the other, through the console as shown below. Make sure it clears parking brake cables the console screws and parts. (In this photo, I'm about to pull the slack to reduce the size of this "loop" of 12 gauge speaker wire.)

The above photo shows an amplifier that someone mounted to the floor of a 964 (993 similar) at an angle. This amp has a high profile along the inboard and outboard edges, and must be "aligned" properly to clear the seat mechanism. If you don't get the amp in the right spot, the seat will hang up on it. Watch also where the seat's power harness is so that it'll move freely when the seat is moved front to back. This is a great little 2 channel amp, by ARC Audio (Robert Zeff, the man behind Zapco's older stuff). I had to relocate the "rear" of this amp (on left in photo, towards rear of car) inward a couple inches, the front end of it was alright. It was probably no more than an inch inward. (In the photo there is a harness under that leg of the amp. No, it isn't pinched, in fact it's not even touching the amp, it's laying below it about 1/8" with no tension at all on it.)
