Here's what I've come with, suggestions or changes are welcomed!

Code HU to HiFi

Technic Stereo 2/4 PnP Harness

JL XD400/4 Amp

Rainbow SLX 210 Components

SWS-8 Earthquake Subs

I too has been thinking of going this route, I have a e93 base so my concern is about mounting depth of adding components speakers, I was thinking of just adding the alpine hifi speaker upgrade with the technic Stereo 4/6 harness and Rockford Fosgate Punch P500X4D and powering the under seat sub with a MTX TD1000.1D amp that I already have and adding JL audio clean swap CL441dsp. My question is has anyone done this before? Change out the stock base speakers for the Hifi upgrade and adding a 4ch amp to them, if so how do they sound. Sorry if this is
