Here are some pictures of the custom speaker pods my made for my 2013 Spyder RS. The speakers are 5.25" Polk Audio marine speakers, pods are made from 5" schedule 40 PVC caps. The are mounted to a custom made steel plate that lays over the dash. The system is powered by a 100 watt amp that is mounted in the frunk. I am using a 7th generation iPod Nano for the music/radio.
