I've installed a few subs and it depends on how big the amp is for guage size. I'm getting ready to install mine and I have 8 guage. You really shouldn't have your ground wire more than 5 ft away from the amp and you don't want the amp too far from the sub.There is no difference between the battery ground and the car ground since they are connected to one another. You can find a nut to take off which is grounded and take the nut off, put the ground wire in there and out the nut back on. I would use a flat head screwdriver to remove any paint which might be on it.Hi
I'll start off by saying I've installed many subwoofers into various cars and have no problem understanding how it all works and how to do the wiring.
Since this is my first brand new car I want this to be a clean, "stock" looking set up. I'm wondering about running the amp power wires and would like to know what is the biggest gauge I could buy that would still fit in the interior trim channels.
I'm also not a huge fan of just grounding to the chasis of the car and would likely want to run a return wire to the battery as well. With that in mind, would I be able to fit lets say two 4 gauge wires into the trim channels and through the grommet in the firewall behind the clutch pedal?
You can check if the remote wire is getting power by using a multimeter. I would also check your main power wire and the ground. Also make sure the fuse for your main power wire and fuse on the amp (if it has one) are not blown. Also check the settings on the amp to make sure it’s set to turn on by the remote wire.I am having trouble with my amp to turn on
My pac is behind the headunit with the rca connected to the amp , my remote wire didn't work on the pac so I just used the fuse box for the remote wire and grounded my wire on the passengers seat bolts .
Still no power 3 new photos by Evolution 8 here some pictures
