Hi guys I've spent the whole day searching and can't come up with a great answer.
I have a 2007 530xi business nav non L7
At first I was going to just replace the factory subs with earthquake sws-8xi's and put a decent aftermarket amp on them but I am seeing reviews saying they do not sound all that great. I do listen to Edm quite a bit and like really low bass.

I have a couple of fubar 10's and was considering putting one in a corner pocket enclosure but all the boxes are for the driver side only and I have a hump in that side with a plastic tray and some door that opens to nothing? Just carpet underneath. It says they are for non L7 cars and I don't have L7 yet I took that panel off and there is an amp/ecu of some sort on a bracket.

So my question is are there any alternative enclosures? Would I be able to move that module and replace that panel with one without the hump/pocket thing or even cut that out and have the box cover it? Any enclosures like the e90's that go in the passenger side pockets?

Also I am still keeping the sws's in mind so any input on those would be great. The amp I have to use is a kicker cx600.1

Thanks in advance.
