Right, i am fitting a car stereo. It is
this one. It has 4*45W peak.
My van doesn't have a harness for the stereo, so i have bought this:
http://www.maplin.co.uk/Module.aspx?ModuleNo=99497The van does have stock speakers, with cables running to the dash. I have used an AA battery on these to see if the speakers move, and they do. This means the speakers and cables 'work'. I need to get to the back of the speakers to see their power rating. I'll post that here once i do.
To connect the speaker wires to the harness cables linked to above, i got
this. Will this be ok? Is 10 amps enough or suitable?
In the dashboard, there are two wires coming out of the back of the cigarette lighter, a red and a black one. I have tested the red one with a multimeter and it is the ACC switched one. The black one will no doubt be earth, but i am going to earth the harness above to the body of the car.
My main problem is the constant, as i will need to take a power supply from the battery to the stereo.
So, i need to know what kind of cable to use, what Amp/Watt/Gauge cable to use between the battery and stereo. The distance between the stereo and battery is less than 3 meters/10 feet.
The fuse in the back of the head unit is 10amp, so i will also place an inline fuse near the battery just to be safe, which will also be 10amp.
I have bought a 6 metre 8 amp cable for this, but have no idea what gauge it is. Should the amp of the cable match or be higher than the fuse, so that the fuse blows before the cable melts?
