Buzz dont sound good. Start by ensuring the sub is sealed. Ported or non ported box, you need to make sure air isn't leaking from any spots other then port. Amp should be in LPF, obviously for low pass, and if theres a variable knob to adjust the freq., you might want to set it around 100hz. If theres a subsonic filter, you want it around 30hz probably, and if theres a bass boost switch or variable adjust knob, I'd leave it off. If its a knob, a little 1/4 turn shouldn't hurt, but bass boost on a sub amp is something you SHOULDNT have to use...
I'd set Gain to about 1/8 a turn, & turn your deck up until your speakers crackle, and back it down a tap or two, then adjust the GAIN until the bass sounds washy, then back it up where it sounds clean. That would be a generic set GAIN, and see how she sounds. Biggest issue with ppl who get systems but dont know alot about it, is they think the GAIN control is a volume knob, and that you just turn it up all the way, or almost all the way.
Not good. lol
Another issue with buzz might be alternator whine int he signal, which could be from running a power wire along side the RCAs, or just cheap RCA / power cable to begin with. In my experience, a ground loop noise filter will help, but whine can still be present.
Hope I helped!
