    Thanks Epoe. I chose to unplug the factory sub altogether.

    I would imagine that not using the sub line for input may cut out some very low end (35-50htz) due to crossover. As you said the sound at that low a frequency is subjective to the listener and music listened to. I have listened to rap, death metal, NPR, hard rock, Phish, Ghost, and some hard core EDM. They all sound great on that Rockford Fosgate. A 5000% increase in sound in the low end, and I highly recommend it to anyone who may come across this thread!

    Hey, sorry I haven't kept up on this thread. Got real busy for me. Can someone who got the Rockford Fosgate that doesn't have any sound issues show me their setup and how they wired it? Thanks! I kind of wanna get this done soon now since I have time.

    I just picked up the P300 after doing some reviews, evaluation of what setup I want, and after reading this thread.

    I don't mind the system as a whole, I just felt the Bass was lacking at higher volumes. When I listen to some bands like As I lay Dying or Parkway Drive for example, the double bass doesn't "click" and "punch"/cut through. TBH my system in my '04 Corolla sounds better to my ears...

    Anyways I know nothing about Car Audio install, how much would a job like this relatively cost? I am assuming I will go the same route and bypass the factory Sub.

    Anyone know a good place in SoCal or LA?

    I should have got into the Car Audio business... must be like shooting fish in a barrel.

    Seriously, you went out and bought a P300, without knowing anything about Car Audio Install, or what it will take to install this in your 2018 Si. ? :doh:

    I assume when you say P300, you mean a P300-10 or P300-12 Powered SubWoofer.

    I would suggest you watch a few YouTube videos, about installing Powered SubWoofers , so you can appreciate what it takes -- then you will be better equipped to evaluate what the Car Audio Installers are quoting you.

    Knowledge is Power :(

    Hey guys, so it's been awhile but I finally ordered a Rockford Fosgate P300-12.

    Just have a few questions on the install if anyone out there will see this response to the thread.

    1. Where on the chassis is a good spot for the ground connection? I would like to keep it hidden, probably along the path with the power wire and not somewhere in the trunk.
    2. With the factory speakers, what do you guys have set for the Gain and Crossover?
    3. Would it be better to get signal from 1 speaker and the factory subwoofer? Or just the factory subwoofer alone?

    Thanks guys! If anyone could post pictures of their setup that would really help.

    Bristol Sound in SoCal did my install of the P-300 and LC2i. It sounds amazing! The shop definitively knows their stuff and it was a pretty clean install. I did my research, bought all wiring and equipment needed so they only charged me for the install. They also give you a discount if you pay in cash!
