It's an easy DIY. The hardest & most time-consuming part of the fit is actually removing the side trim for access to the HK loom!

So you upgraded the underseat subs? What did you replace them with? And what was the benefit? I can't imagine anything 8" under the seat creating any amount of decent low end! |
With the HK system, the subs are 8" actually.
I put in a pair of Audison APBMW S8's. They're a direct plug & play replacement.
As the HK amp is digital, it can vary its power allocation (as I understand it), so to gain the maximum benefit i fitted a Hertz class D amp, just to power the new subs.
With the HK amp no longer having to drive these with anything other than a signal to the Hertz, it allows better power distribution to the remaining 11 speakers.
The resulting sound is fantastic, with no distortion.
I went with the Audisons based upon reviews, but several manufacturers produce similar units designed specifically to directly fit BMW's enclosures.
