After listening to few, Arc audio sounds great, however if you can, Fosgate will sound better. They have dedicated plug and play systems and are waterproof. If you live in atown like mine, we only have a couple of car audio places, and they charge an arm and a leg... I got the fosgate system with amp and did it myself for less than half than it would have costed at the car audio... wasnt very hard and if you're careful, and read the instructions that come with them, it will be really no problem and done in one afternoon...Night and day difference on my bike and now we can hear the speakers LOUD and CLEAR at 70MPH... BIG thumbs up.
