Gonna buy another pair

They were a Christmas gift for fiancée for our Harley. He really was excited to get them and plans to order another set for the Tour pack. Shipping was faster than Amazon or anywhere else I ordered from as well so definitely have our business!

Jeremy Schipper

Amazing sound quality! I’m now PRV for life. I bought this 2016 Road Glide with all PRV speakers and I will build my next stereo with all PRV as well. Great product

6.5” Carbon Fiber Coax

Unfortunately I received the wrong speakers. I ordered the 6.5” Carbon Fiber Coax’s. but received the 8”. Talked to a very helpful Tim and Suki in customer service and had the 6.5”in 4 days! They are hooked to a Hogwired 300watt 2 channel amp in the fairing of my Harley. They sound INCREDIBLE! Amazingly clear even at highway speeds turned up! They like power and handled all that amp could give them! I have them crossed at 100 hz+/- to 6000 and they do great!
