I have a 2018 SSRXP and have noticed the lack of speakers in the rear of the boat. I have the Kicker KMC2 stereo. I don't need to blast the sound for the entire lake to hear just be able to hear the music at lower levels in the back of the boat. Here is the problem, I know nothing about how to do this. Will this unit even drive 6 speakers? Would I need an amp? Tons of other questions too long to list. Any simple help is greatly appreciated!! Thanks in advance.
