Hi, I’m about to build a “compact” speaker box. Roughly said box in the back of the trunk 1.20 m to 90 50 cm high, about 130 kg heavy with double bonding in the 3 power stages. 2 * 2000 watts max and 1 x 500 watts max. the 500 he I will use as a mid-high tone system and the 2 2000s I wanted to operate with 2 Jackson AL3200 each. Well, since I have read about the AL3200 already much bad I wanted now questions if someone would recommend me another subwoofer/k ann. ( should price also max. so around 100 € lying per piece ) Continue the question about the position of the bass reflex tubes, is that no matter where I install the one? Diameter length is calculated that is clear, but the position in the housing? Would be nice if someone can help me there, or helps me there. Greeting Dodi
