Sub and amp fitting

[Danny2009]

If your buying a wiring kit it will come with everything

You need one set of pre outs on the head unit

The RCA leads go from the head unit to the amp
There will be a little wire as thin as speaker wire that goes from switched live on the head unit to the amp the instructions you get with the head unit will tell you what wire this is just splice into it

You also need a earth good point is the bracket that bolts the seats into the boot it's at the back of the boot in the corner as your stood at te back of the car, scrape what paint off you can to get a good contact

Then the power lead comes direct from the battery to a fuse that's in the kit, then through the car into the amp and as you say speaker wire from the subs to the amp

If its all wired correctly at te head unit the amp should turn off when the head unit does so no flat battery

Hope this helps
