I have been working on a online site to provide turn key high end sound systems for the slingshots. We have been doing a ton of R&D work to figure out what would be the best sound systems to install. Would love to discuss with other Slingshot owners what we have been working on. We are working with local slingshot owners to build fully tested complete sound and entertainment systems. I also designed and installed the system in my personal slinghsot. I have been in the car audio industry since 1989. Would love to hear from others if you are interested in what we have been working on. Thanks!
