You don't need to take the earth wire from battery to the boot just find a good earth point in the boot close to where you will have the amp.

tomdscooby

going TO the boot - down one side of the car under carpet:

Power lead direct from battery, inline fuse near battery,
Remote turn on wire from your stereo

on other side:

Rca (pre out leads) from stereo.

connect to the amp,and run a short length of earth cable(or power lead,but mark with tape so you know which is which!) to a bolt with a washer through the little metal hole just inside your boot near rear light,but under the carpet. get some sand paper and remove the paint here other wise you wont get a good connection.
like this


hope that helps

p.s ignore the mess of leads...i need to sort it out! only been in 19 months

p.s, thats a power cap in the pic

sorry i meant power lead

oh lol, there is a big(i mean big) grommet that some leads already go through the bulkheadto the right of the intercooler,cut that rubber a lil more if needs be and feed the wire through there, then its just a matter of getting trim off and carpet up and feeding the wires to the boot.easy enough



you can see from this,its the thick blue wire from the battery

i ran my power wire under the car and in under the back seat. but i use 0 awg 50mm2. i've got a 1600w rms amp and 2 x 12'' rockford dvc subs.

no offence, but i would take the power cap out. they don't really help.

Is that gromet in the same place for a 99 wrx?

tomdscooby, i've just noticed that you haven't changed to earth wire from the batt to chassis. it should be the same size as the power cable you are using.
