Umm no. I’m going to have to respectfully disagree with that being the “proper” way. Like Mx6HOSS noted, the battery on the six is located on the drivers side of the car and assuming that the amp is being mounted in the trunk; it is more straight forward to run the wire on the left side of the car where you’ll reap the benefits of a shorter wire and a relatively straight feed to the positive battery terminal or the positive terminal on the fuse box (also located on the LEFT side). There is also a rubber grommet on the left side where you can snake the power wire through there into the engine compartment.Courtice6er said:Don't do any of those. There is a proper way to do it.
Underneith you dash on the passenger side there is a rubber gromet the goes threw the firewall. Run it threw there, you have to use a coat hanger or somthing the will just puncture it but not cut it. To find it lay the passenger foot well and look up under the dash, there are already some wires going threw there. also this way it is still sealed off from the engine compartment.
