Help needed for new sub woofer/amp hook-up to factory 14' head unit!

[Pat Scullion]

Hello everyone! I am in need of some help setting up a sub...

I do no know much about cars or audio for that matter. I just bought a 14' Si coupe a few months ago and just purchased a used sub/amp set-up from a good friend and am in need of help setting it up. Here is what I currently have:
Kenwood 1800watt mono amp

12" Kicker L7 Sub-woofer

The sub is already in a custom made box with the amp mounted on top of it. I plan on placing this in my trunk..

With those known what types of cables do I need for sub-to-amp and amp to head unit? I understand I may need a line-output converter to RCA inputs of the head unit (suggestions on a brand?).

Is it difficult getting to the back of my head unit ? And do I need to take out the stock amp since I am plugging in a new powerful one?

I just want to use my car speakers for sound and then the sub for heavy base (yet customize the sound a bit to not be crazy with bass but loud if I want it to be).

How does this all come together? Any suggestions/ help would be GREATLY appreciated!!

Disconnect the factory mid woofer on the rear deck. Install a LOC off the rear sub wires, buy a 4guage amp kit that should have all the wiring you'll need. LOC lile anything can be cheap, when going cheap you always sacrifice quality there are 100's of options. I'd suggest doing some research and going from there as to what will work best for you.
