I have a 15 S/G Special with biketronics 4180 amp and 7.1 speakers. I bought a king tour pack and want to add tour pack speakers and bag lid 6x9 speakers. Would like to run tour pack speakers with 4180 and get a another amp for the lid speakers. What brand lids and speakers and amp do you recommend for bags and location for amp, bag or faring? What brand pods and speakers for tour pack?
