Alright, I think I am about to run the wires for my sub and amp. Are there any tips or tricks you guys would offer before I go and install them in my 07 civic w/ nav?

 

make shure nothing will cut the wire inside the car... if ur going to make a hole in the firewall make shure u have that sealed up after other then that idk what other tips will help unless ur going to run the wire under the car

 

You're gonna install an amp and sub to your nav system???

 

no i only put nav so you would know what kind of head unit i had.

 

Is this a stock head unit?

 

yes it is the factory HU w/ nav

 

Have you already found a way to wire the amp to the head unit, or are you just going to connect into speaker wires.
In other words, in there a sub output or any pre-outs in the back of the head unit?

 

There is an 8" sub in the rear deck. i think I am going to use a line out inverter from that.

 

Sure.



Run the power wire and RCA cables separate from each other, they don't have to be on the other side of the car, but at least a good foot or so. If you want, upgrade to shielded cable to avoid picking up outside signal or causing interference.

Try to keep the wires away from any other signal or charge emitting device such as other cables, lights, gauges, etc.

Use a sufficient power and ground thickness, the more the merrier.

Upgrade to the "big 3" which consists of a larger alt to batt wire, and better ground

Make your cables/wires as short as possible, this allows for less resistance and less outside signal to pick up

The thicker and smaller the ground cable from the amp the better, try to keep it within 15 inches, and it should be as thick as the power cable.

Properly clamp down the ends of all power or ground sources, make sure you don't ground your amp by screwing into the wire ends.

Don't keep your amplifier in a location that it cannot get ventilation

Do not attach your amp to your sub box

Use sufficient sized speaker wire as well
