Sub Problem, Hopefully Minor

[2fst4u]

my sub keeps wanting to fade out whenever i turn my hu up. i'm thinking that it may be a ground problem, but i wasn't sure.

where do you guys have your ground wire located. and what prep did you do to this area.
thanks

Mount it to one of the the strut bolts, maby take some sand paper and get the paint down to the metal and you should have more than a solid ground.

just bolt it to the seat belt bolt or in the area where the removable back seat latch is.

i have it on the strut mount right now. but i should probably scratch the paint off of the body there. i also resealed the box with a new gasket. i don't know it seems to have helped.
