Hey guys. I am upgrading the sound system on my pontoon. I just put 2 pair of Polk 6.5" speakers in, I bought a Polk 660 amp. I was told by someone that I can run the 4 speakers off 2 channels and run a sub off the other 2.
What would be a good sub to run for this set up? I dont want to spend alot of money due to the fact its on my pontoon. Is there a free air sub that would be decent, or are those a bad idea?
Send me your thoughts and ideas. Not for sure if I will put a sub in, but Im entertaining the idea
