Pete's the best. End of story. . Stuart.
He did my system in the '11 SERGU, had blown speakers twice, he shipped new ones with return slip, no cost.
I made a mistake on that bike by replacing the head unit, the first Sony I had installed, I could not see the screen, switched that out for another Sony and not much better.
I am thinking of going Boom Audio stage II, the bass response even on the stage I I have is awesome for a bike and I do not want to risk losing the audio quality.
The first time the wife rode on the '11 after I spent almost $3K on the audio upgrade she said "The stock stereo sounded better"
I think I had to agree with her even though it broke my heart.
I think the Boom Audio on my '16 SERGU sounds really good, maybe not all that loud, but MOCO really started paying attention to the acoustics IMHO
