Review: アンプガワリにマジェスティに装着しましたが最高な音質になりました
Review: This came in as advertised and was the perfect size for my 1996 Goldwing SE.. After removing the outdated factory radio there was plenty of room to use the old radio cover as a mount point for the remote unit. A little Dremel work and it fit like a glove. Sound quality through the 4 new Pyle Marine speakers is outstanding, I also used the line out to control an 8 inch sub in the saddlebag.I love the fact that even when you turn off the power the unit remains on to shut off gracefully.Bluetooth works flawlessly and was very easy to set up on my android phone, I drove the wing over 200 miles yesterday in 100+ degree temps and there was no overheat issue at all. I am totally happy with this and I'm seriously thinking about another one for the Dune Buggy.
