So what we have:
Golf 4
12" Fi BTL N3 dual 1.4 coils (0.7 wired)
MB Quart Discus 2000.1 (true rms, same board as on AQ2200)
65Ah battery (noname, but soon will change for Stinger 1700)
0/1 Ga from (only + connected directly to battery)
Alpine 9886 HU
What we need:
Maximum dB output that we can take from it. Im thinking about 1.7 cuft clean vol. and four 110mm diameter tube ports tuned 50-53 Hz. But they are too long, what do you thing maybe it will be enough to use three tubes? Also what do you thing about clean vol. that i choose for box? And maybe somebody know Golf 4 resonance?
Thanks.
P.S. Now sub is playing in music box, you can watch it on YouTube:
