i know this may not be the best place to post this, but this is actually a question for my boat not my SCrew... but here goes:

the boat comes stock with a kicker 4 channel amp (ix404) driving the six kicker boat speakers and 10" kicker sub. that sounds WAY underpowered to me.

plus, I want to add tower speakers (probably Boss B50s or B60s). I'm thinking I could use the stock amp to drive the tower speakers, then get a 5 channel to take care of the sub and the 6 boat speakers. or possibly get another quality 4 channel to do the tower speakers and bridge to the sub, and leave the stock amp to do the 6 boat speakers...

any suggestions would be great...
thanks!
