Additionally, did you try to swap the phase on the subwoofer? In some cases, that's all it takes to make a difference (along with woofer positioning)
Well, I’m a little disappointed because I just transferred over my bass setup from my other car to my 2009 mercedes e350, and it’s wired up perfectly, but I can hardly hear it inside! It’s in the trunk, and my car doesn’t have the fold down seats option. The sound deadening is so heavy back there that it sounds like it didn’t even make a difference. Open the trunk and you can CLEARLY hear it very loud and rattle anything it wants, but it feels stock while sitting in the drivers seat.
Has anybody else had this happen, and how did you fix it? Can I remove the sound deadening to let it travel through, and where would this be (W211 chassis)? Perhaps I need better sound deadening around the trunk seals? Would really appreciate some advice, I’m extremely disappointed.
Thank you in advance.
