Loving the upgrade from my i4 M50, but seriously, where's the bass?! This stock system is all treble and mids, the low-end is MIA. I'm itching to throw in a sub and that hidden compartment in the trunk looks like it was made for it. Anyone already done this? Spill the tea - what subs fit, how'd you wire it up, any tips for a clean install? Bonus points for pics or vids! Thanks in advance.
