JL Audio Subs

I know, the belle is basically a ST-300 and and ST-1000 in one amp. It should push the M3's nicely, just make sure you build the enclosure correctly and don't use a prefab. I gave mine 1.5 cubic ft of airspace per sub, the memphis rep suggested this to me even though the website recommends 1 cubic ft per sub. I must admit that they hit really hard and clear so he must of known what he was talking about.
