I have a 2009 Moomba xlv, and I just bought a new 12"kicker l7 and a pair of wetsound pro-80s. I also have a dual battery. Should I get a SYN 4 or a SYN 6 amp to run this setup?
Also, is it worth it to buy an equalizer in order to tune each component separately?

P.S. Im new to the audio scene and really appreciate the help!
