Install isn't very difficult. Created a guide on how to do so if you want to follow

Have since done more audio upgrades replacing all factory speakers and additional amp/dsp installed... But if only more bass is what you're after than the above guide should be all you need to do this yourself.

Good luck!

Thank you, should have tried this myself but went the lazy route, having it installed professionally in a couple of weeks, dumbest way to set money on fire: lol

Never had any other car other than a bimmer . Never hand a bimmer without 2 12" in the back JL or rocksford fosgate . Base knob is a must . I have installed under my drive side so I can adjust and only make it hot on the freeway on certain songs..

Got it off OfferUp for 200$ with amp and box and 150 for install with knob..

M2 here but I cut a hole in the rear deck to mount a sub and am very happy with the results.

Going to be putting a sub in my m340. Have a quote for a custom mounted sub that would sit in the trunk floor with a custom box and metal cover. Would be 2 10in jbl and a 1000 watt amp. wendy's lunch time surveyzop.com

Hi
I have 330e g20 2020,
I am struggling to fit a after market sub and amp, I used lc21 and vibe RCA both didn’t seem to power the sub through the amp. The amp power light keeps flickering and there is no power in sub, I have used the underneath driver side sub wire to run the wire to the boot. The amp is connected to battery in the boot, (there are 2 batteries) I used the big one. I have used remote from cigerrete lighter fuse.
No hope if anyone can help.
Thanks

You're not alone and I am starting to wonder if this is a Hybrid issue.

For more detailed info check here: https://g20.bimmerpost.com/forums/sh....php?t=2113316

Maybe you can reply there with some more details on the components used and pictures of the installation?
