In the quest for better sound, I changed out the ceiling speakers in our 369RL. Took out the factory 1 ways, and put in 3 way JBL GTO-638 6.5" speakers. Nice change. I'm thinking I will go ahead and change the head unit too. I will most likely go for an automotive dual din unit. Something with a decent amplifier, or external amp capabilities. I'll build a different face plate for where the head unit is, and then possibly wire a 4 channel amp behind the head unit. We'll see how it works out.
