I have installed the following amplifiers and bass box: TWISTER F2-300 2x 150 Watt RMS @ 4 Ohm Stereo 1x 750 Watt RMS @ 2 Ohm Mono 1 Ohm stable RADION 12BR-2 2 x Radion 12″ Subwoofer 2 x 42l Double bass reflex housing 2x 300/450 Watt · 2x 30cm I play with the thought of replacing the box with something smaller because it takes away a little space, I would like to keep the amplifier. I am not so the car hifi specialist and I am looking for an alternative that fits to the amplifier. be as good as the 12BR2 is, is there anything smaller that makes just as much pressure? hear mostly Hiphop (no Techno….etc.) otherwise I would be happy about some suggestions. “…UpRockA…”
