Well the 2.5 Inch Pyle speakers lasted 60 days and one blew.
I paid $40 for the set and they want $20 shipping to replace the blown unit, so I removed both.
I'm currently looking at some larger units (4"). Not sure if they will be amplified or not.
I like the mounts I made that come off the luggage rack mount points, but I keep thinking that a speaker mount that incorporates a slight backrest lift might be the way to go.... Just thinking out loud.
But I wanted to tell you guys that those (Pyle PMC30 I believe) speakers are NOT the way to go.
