Background:I have been in the auto stereo/ and car scene since I could drive and even before, and take pride and passion into the hobby. since I've been out for a few years, I have noticed that there is new technology to learn, and products to research. So after initial thinking and planning, this will be my set up as late as next year, or as early as fall. Between vacations, and other places money is going, this mod isn't (nor are any of my "custom" mods) High on the list. But I'd thought i get it out to anyone looking for a good/great set up for the bikes. I always feel that if you have to spend some extra money to get a higher quality product, then it is meant to be. so that being said, i also understand that people don't have thousands to spend on stuff. First is the amp, my number 1 choice is the Alpine PDX 4.1. This marine grade amp is ready to go to pound town. Plenty of power for everyone, electrically safe to be in the weather and its marine grade, that word is meant to make it seem more durable. The speakers that I'm going for is the polk dxi 650's. This is a 6.5" speaker, with a tweeter. as you all know the larger cone allows for better mid range, and the tweeter allows for those crisp highs. these are separated (mid cone is continuous in the whole bowl) to allow for much better sound. So next to these products, ill need the 6.5 bezels, wiring and about a case of beer to get it in the bike, The amp is slightly larger than the rockford fosgate pbr, but there is a ton of room behind that faring, unless you want to give up some of that bag space. I'm shooting to get it in the fairing though. Hope this helps some, or raises more questions for others.
