A friend of mine and I recently swapped out the stock head unit for a sony ms60 and added a hawg wired 150 watt amp with 2 hertz 200 watt 6.5" speakers on his 13 glide. I have the stock head unit and the boom audio upgrade 5.25 " speakers in my 12 glide. The difference in sound is minimal to the point that he does'nt believe his sounds any better than mine. So my question would be does any one think there is a problem with the setup? Because the difference between $1,200.00 and $125.00 there should be a huge difference in sound and sound quality. Any help would be greatly appreciated.
