Nice result!

Good to see you used a beefy power cable. Too many people save money on those ...

Yeah, but most people who beef up their power cable for get to beef up their earth..

REMEMBER - Your Earth can never be too BIG

Yes and no.

I know what you mean but the distance and thus the resistance of the earth cable is MUCH smaller so it is less important to upgrade.

The reason that we use ridiculous large cables in cars is because of the low voltage. Low voltage is much more influenced by recistance. and resistance in a cable is measured by voltagedrop per meter. So clearly short cables need to be a lot les thick than long ones.

From the mouth of many a great audio installers and my best mate who is an autoelectrician....

Create a nice short earth, fatten it, and ground the mutha..... :P

The earth I had on my am was a 8 guage and ran from the boot back under the rear seats and grounded under there, however I found I was losing power and also experiencing cut outs from the amp.

Replaced the earth with a 6 guage and shortened it to earth under the baby-seat bolt, and waalaa - no more problems,...

The only reason I went 4 guage was because of the coustic amp. Its putting out 600RMS into 1 sub at 4ohm and its recomened in the instructions. The alpine v-power only produces 4*40RMS at 4ohm (my old amp was 4*60 RMS but I fried it in my last car) so it wasnt an issue but i had plenty of cable left over (I still have 2 metres left). Im using a Stinger earth for the coustic and a small no name for the Alpine. Stinger Positive battery terminal also.

Spare Tyre is sitting in the garage. Alot of new cars dont even come with spare tyre (eg bmw 120i). Plus the wait of the spare tyre is replaced with the stereo, so no real diff in performance.

Most auto shops now sell that 'spare tyre in a can' stuff. It's a mousse like product in an aerosol can that clips onto the valve and you fill up the tyre in the event of a flat, and it provides temporary relief for minor punctures like a nail.

Obvoiusly won't work if you've shredded the tyre...
