I have some sort of an idea but could alot of help. I also have 2 boxes. a sealed box and vented box. I have 1 12" JL W3 powered by a Alpine MRP-M500 Sub details: 12" 4-ohm subwoofer power range: 100-500 watts RMS peak power handling: 1,000 watts frequency response: 22-200 Hz amp details: mono subwoofer car amplifier 300 watts RMS x 1 at 4 ohms (500 watts RMS x 1 at 2 ohms) variable low-pass filter (50-200 Hz, 24 dB/octave) variable bass boost (0-12 dB at 50 Hz) |

Here is one http://cgi.ebay.com/JL-AUDIO-J2-500-1-MONO-CAR-AMPLIFIER-BRAND-NEW-/280503703377 ?cmd=ViewItem&pt=Car_Amplifiers&hash=item414f52d751 |
