Hey guys,

I recently purchased a 2007 Bf MK2 XR6 (non premium sound I think), I've been having an issue with the speakers where there's absolutely no bass at all not even a slight thump. I tried using the aux cord the previous owner had put in using the adapter under the dash but that changed nothing, using radio also has the same results. I've tried turning the bass all the way up, turning off the power limiter and even pulled the battery out to reset it.

I was wondering what could be done to fix this? I had a BA MK1 XR6 and it had a hell of a lot more bass than this.
