Boom in 2012 limited
 

Happy with 4 speakers thinking of the amp does it make a difference at 70 mph?
Lots of money for boom amp like 400 bucks

yes it makes a difference. Save yourself some $$ and don't use the boom amp. Get an alpine ktp445u amp and mount it in the fairing. Amp is about $115 on Amazon and that's all you need.
