Answer 3

ok assuming you have thick enough gauge wire here are some dont dos for grounding..........

1. dont ground to seat belt bolts

2.dont leave ground loose

3. dont use the same ground spot for both amps

4. dont rule out manually grounding your cd player as well

5. dont run RCA signal cables near your power wire

6. dont ground to tire wells or door frames(find a bare metal spot on the floor or under neath the seats)

some Dos...

1. use at least 8 guage if under 400 watts and go up to 4 guage if more than 400

2. make ground cables no more than 18 inches in length

3.scrape paint from metal and use washers or ring terminals rather than bare wire

Answer 4
