Replacement HD Roadglide speakers.

I needed replacement speakers for my Harley Davidson roadglide that I kept blowing. I read several reviews on these and decided to purchase. Install was fairly simple with just a little modification. First test they sounded great. Shipping was fast.

I'm on my third upgrade on a Harley-Davidson and this company by far is the best company I've delt with! Brian has went above and beyond to help me with a few hiccups I ran into and I will definitely be purchasing from here for all my future audio needs!
