Power Amplifier / Cable Average / Subwoofer

Moin moin together, I’ve been researching the Internet for a long time and I’m not really the forum user, but since I’ve often read something useful here and most of the time I want to answer the following questions. I have the following components: Hifonics ZXI 6404 Power Amplifier Hifonics MXT-12BP Subwoofer Hifonics 1 Farad Power Cap My questions would be the following, maybe someone can finally answer me of my doubts: 1) A colleague of mine says that the installed cable with 16sqm m average is enough for my power amplifier, but I doubt it and even think that I have to switch directly to 35qmm cables. What do you think? If with how much A do I have to secure the cable? (My power amplifier has 2x 50 A fuses) 2) Furthermore, I would like to ask, is this power amplifier enough for this quite powerful subwoofer or is this not even overexcited? 3) I wanted to hang my 2 front speakers with the power amplifier. Shouldn’t be a problem in itself, or? 4) Rich t the 1 Farad capacitor in connection with this power amplifier and the subwoofer? 5) I have partly read that the mass cable should be better a number thicker. If it really is, why? (I would have to put 50qmm mass cable then :S 6) Now probably comes the stupidest questions, but I don’t know anything about it. My power amplifier has 4 channels… From the front comes 1 chinch cable (2 connectors) which hang on my power amplifier. My colleague told me, rather such a Y adapt he buys to make 2 chinch cables (4 ports) from a chinch cable (2 ports) at the rear of the power amplifier, so to speak. What does that bring or why is that good or I ask further, when do you need something like that? You don’t know how I would be grateful if you could help me. I love music and I like to invest there, but not too much. Thank you in advance. LG oli13371
