Rubber Grommet? Amp/Sub install
Im going to be installing a 12' sub in my '98 non turbo s70 sedan. Does anyone have any advice before i start installing? The only thing im worried about is wiring the amp power wire to the vehicle battery. Where exactly can i run the wire though the firewall? Is there a grommet somewhere, or if anyone has a picture of where its at or alternative method?

Sorry I missed your question about the ground. I am upgrading from two 12s with a 2 channel 600 watt amp @ 4 ohms to one 12 with a 1000 watt class D amp, before I had just sanded a small spot under the carpet and used a self tapping screw, but now, I havent quite decided yet, thinking to attach it to the small steel bar that the back seat latches to, but the most important thing is to have good contact against bare metal, oh, and use an 'O' ring clamp on the end of the ground wire, I have seen too many people try and just wrap the end of bare wire around a screw and drill it in, this is very sloppy and will come loose and prob result in shorting something out.
Edit: shorter then 1 foot ground wire is most common advice, I try for 7 inches or less, check the Manuel for your amp, alot of manufacturers recommend that the amp be mounted vertical (the best for a short ground) or inverted for the best positions for keeping the amp cool.
