Glacierpearl, i have one word for you.. BADASS.. cool system on your bike man.. Iam actually in the process of doing something similar on my electra. Instead of 4 6x9 iam just putting one on each bag, and I am still shopping for a small amp to push them. Very similar in style too, i drilled holes on the inside for sound< although looking at yours, I will go back to drill bigger holes now. ONE QUESTION> I have a concern of slight rain, or when i wash my bike, how will I keep water from entering into those holes we drilled in the inside of the bags???? any suggestions??? Damm i hope i dont mess up my new 6x9s with water...
