I have done a search and not really finding what I am looking for.

I have a set of the of the Polk MM651 speakers already installed with the factory HK head unit. I am looking at adding the ARC 125.2 amplifier and am wondering if anyone has done a write up on the install. I am wondering if I need to get arc's amp install kit and once it is installed I what settings I should use on the amp with regards to gain, crossover, and output. I know this is pretty noobish but trying to save some cash by doing it myself.
thanks in advance.

 

Any amp install kit should work as long as you get the correct gauge wire for power and etc.. You can always buy the wires and fuses individually also. In regards to the settings, I think you will have to listen and fine tune these to your liking. There is a thread out there somewhere that talked about the gain settings. Check youtube also for install instructions.

I'm going with the RF300x4 and plan to get a basic install kit from walmart.
