92 Sport Nautique Customizations
 

So I am looking to freshen up my 92 Sport Nautique a bit this winter and am looking to see what others have done. aside from adding tower speakers im looking for ideas on the following:
1. Sound System ie: subs? Speaker Locations?
2. Ballast: other than the ski locker where else have you hidden yours? Has anyone successfully converted this year nautique to internal ballast? Has anyone figured out how to get the wake to surf capability?
3. Maximizing/increasing storage for life jackets, anchors etc?

any other additions or customizations that anyone wants to share is appreciated. Pictures are super helpful.

I know not exactly what your looking for, but here is my 92'
