Hi,

I recently had all my speakers replaced and upgraded to include all three door speakers and two new subwoofers behind the seats. (FType Convertible).
After all the expense of doing it, and a full day in the audio shop stripping the car down to fit them, I'm beginning to wish I hadn't bothered. The sound is crap. Very little bass despite the two new subwoofers that were fitted.

The issue seems to be that the car didn't have them fitted when it was new, so the interface audio options don't allow me to turn up the subwoofer volume or balance the speakers or fade from back to front. I've been told I need an audio file configuration change via SDD.

Can anyone help?
I'm in North West England.

Thank you.
