Calling all ICE experts

[Lloyd]

I need to seek some advice as I 've just fitted a new Alpine Head Unit in the car. It's a fair bit more powerful than the OEM Sony unit, so I have ran a new 12v feed (17 Amp cable with 10Amp fuse for now) from under the drivers side dashboard. I found a (very) large red cable, perm 12v with a 60 Amp fuse to source it from. I've also taken an ignition switched 12v feed from light buzzer relay as Glyn suggested in a prior post.

My challenge (as I'm fairly new to this) is to find a good place to find a new ground or earth wire for the radio. Ideally, I suppose I should find a large ground wire to match the good new perm +ve feed. As yet I've not found one, and am just using the tiny earth that comes with the original radio car loom.

Can anyone offer advice as to the best place to make the new improved earth connection? Any advice much appreciated!

Thanks,

Lloyd

I've PM'd you instructions on where i grounded mine.

I used the standard ground on mine and that should be fine unless you have some amazing head unit that is planning to draw more than 10A

Good luck

Cheers,

Steve

The Alpines do Fatty i always ground my radio's to the body to help eliminate alternator whine.

I've got a ground loop on mine from the comp but i'll sort that out with an isolator when i install the screen.

Fair enough. I have always seemed to avoid any annoying whining! I am running kenwood though

Yeh well people forget it's alright have big fat positive wire but it's the total journey path of the electrons that count and as such you need equal earthing quality.

Tell that to your mirrors

As Jamo says, you need a good earth to get the best from your system. My advice is find a bolt that bolts into the body, get a crinkle washer, a loop crimp and some 16A cable and connect all together. If you can however it's best to run two cables directly to the battery. This can be tricky but it is worth it. It's all about the volts.

easy way to explan how electron flow is simple-water in a pipe.bigger the pipe better the water flows and n more of it will flow.

Water and electrics?


Don't connect a water pipe to your stereo.
