Installing Mutazu Lowers with speakers

Newb with a question here. I have a 2015 RGS and am going to order the Lowers from Mutazu. I would really like to get the speaker option on them but I am not exactly the handiest guy on the block. Can anyone advise how involved it is to install the speakers? I have a friend that is pretty handy and he'd be glad to help but if it get complicated Im afraid of doing something messed up and voiding my warranty....tia.
