What do you all think? Tower speakers for $80 pair.
I just got these clamps for ~20 bucks each. They come with a bolt that makes mounting through the speaker box easy. I got them through premier lighting.
http://www.premier-lighting.com/sales/clamps.htm I bought some 8 0hm, 5 1/4 outdoor speakers at costco, for $40 a set. I will be using 4 of them on my tower, with them attached to a 2 channel amp crossed over at 100hz.
I am not sure if they will be loud enough to hear riding...I'll post more later. If people want assembly pics, maybe I can post them later.
