Questions installing amp

[YAYSTA]

i just got a 10 w7 and 500/1 amp now i just need to buy the wires and hook it up but what size should i get? im thinking bout running a 18 ft 4 awg for the power but the guy at the store said i should get a 8 awg?

The only upside i see to the 8 gauge is it would be easier to run, otherwise. Go with the 4 gauge for power. I bet you almost everyone on here will say 4 gauge.

Go with 4 gauge power wire.

yea i think im going to go with the 4, will i need to drill a new hole or can i go through an existing with it?

* i found in another thread a grommet behind that black box i i got that on mine so that looks like a easy way, i havent had to pull the trim in my yukon yet im guessing it just snaps out and in like most cars and floor in the door pull back and under carpet and then run to the back ? or am i missing something

use the 4 gauge power wire. there is a grommet in the firewall along the drivers side you can run it thru, then just run it under neath the plastic door trim all the to the back of the truck. thats what i did, heres a link to the install i did in my truck.
