Nah I would not be surprised at all. I know most people are not enthusiasts like we are and all they want is for someone to tell them what is best for them. The truth is though that there is so many variables in the "what fits" line to make it not worth putting on this document in my opinion.

What year?
What fairing?
What radio?
What else is already in there?
What amp rack?
What modifications needed to be preformed?

Hey guys...I used to work for a large stereo store retail chain. Learned a lot while there, in the sound lab. I am NOT a sound engineer. I do speak with them all the time, though. Just trying to establish some credibility...

Generally speaking, for vehicle amplifiers, the best spec you can focus on is THD: Total Harmonic Distortion. The lower the number, expressed as a percentage, the better. Cheap amps typically have a very high THD, so the result is amplified distortion.

Generally speaking, heavier is better. Pick the amp up and compare the weight. Whatever power supply is heaviest, is usually better, longer lasting and more reliable.

Generally speaking, expecting good sound on a motorcycle, is most likely, NOT going to ever happen. It's physics. The BEST sound is heard by your ears when positioned in the intersection of all sound sources ...the speaker's "sound field". If you and it (the source; the speakers) are moving, at different rates of speed and direction, it's damn near impossible to place your ears in the middle of that field. One has a much better chance of establishing a good sound field where you will enjoy the BEST sound while standing still ...like for show bikes, parked bikes, or your living room. Add wind/engine noise to the list of attributes preventing good sound to be heard while riding.

Ahhh not always. Many factors can overcome this within reason.

Bullshit!!! Old school thinking. I have some heavy amps that should like ****, some light ones that sound great. Bad advise.
