I have ran one in a car but not on my bike.
When it was in my car I noticed a little more cleaner volume with my alpine head unit but not enough for what they asked for it.
I was disappointed with is so I took it out of my car and returned it.
No way would you be happy with it on a bike doesn't have enough power.
Just my $.02

I've put a bunch in cars with just a pair of coax and they sound good. 90 watts compared to 22 makes a difference. On s bike it might be different. A lot more road noise to deal with. For $120 it's a pretty good lil amp. I'm going to be running one for my tweeters on mine
