I am currently running two 6.5 tower speakers, with a cheap marine amp. As of the last ride, my dry box is no longer dry and my amp is no longer working. That being said, I have been planning on going with wet sounds stealth 10 for some time now. However, I would still like to keep my tower speakers to cover the lower range since I hear the bars have little bass. My question is, if I run a line out of the stealth bar to an amp in order to sync them with sound bar, what amp would you recommend? I know very little about amps, so I am unsure as far as how many channels I would need, how many watts, and if I should look for a particular one in order to tune the setup? Thanks for any advice!
