How easy is this to install?
I'm no electronic whiz but from what I can see in pictures, it looks like you have to hardwire or splice some stuff into this to get it to adapt to the factory harness.. does it just plug right into the factory harness and then right into the back of an aftermarket H/U?
Or is it a bit more complicated than it looks?

 

5 wires to connect if I remember correctly. No splicing neccesary. Just plugs right into the factory harness. Doesn't get much easier.

 

Yea I just got it today actually I'll be putting in my new HU and subs tomorrow.
I forgot I asked this, no one answered it for a long time haha
