2017C300

Hey everyone. Recently upgraded my sub and speakers on 2017 C300 and giving a breakdown of products, costs, and settings for those interested.

Subwoofer/amp: JBL GT-BassPro12 (12" sub with 150-watt amp). Low pass around 60hZ, bass boost at 0dB, gain/level a quarter turn, and phase at 0. Remote control under steering wheel set to 25%. Cost was $299.

Line out converter: PAC SNI-35. Cost was $30.

Power kit: Rockford Fosgate 8 AWG Amplifier Install Kit. Cost was $90.

Front doors component speakers: Match UP C42MB-FRT (4" speakers). Tweeter set at -3dB. Equalizer set to 9 treble, 9 midtones, 1 bass. Cost was $200. Didn't want to upgrade other speakers.

Shop labor, materials and tax: $480

Optional: Burmester ebay grilles for door speakers, center speaker, and tweeters: $70

Total: $1,100 for a sound system I'm pleased with!

Estimate: Shop gave me a $1,200 estimate to sound deaden the trunk, rear seats, and floor. Told that the doors are apparently sealed and unable to be soundproofed. Anyone have experience with that?

Thanks for sharing do you which wire they tapped into behind the Comand system for the line out?

I've got the audio 20 system and just used the signal from the subwoofer located in the passenger foot well, right next to the air cabin filter.
