[QUOTE="wrager, post: 8239806, member: 660056"] I have an MJ18 left over from my theater build (actually 2). Would this do well as a car sub? I'm happy to build a sealed or ported cab. What are your thoughts? I would have 800 watts RMS @ 4 ohms. Thanks in advance. Z - Nominal Impedance 4 ohms Pe - Power Handling 700 watts SPL - Sensitivity 90.7 dB/watt@1m Re - Voice coil resistance 3.6 ohms Fs - Resonant frequency 24 hz Qms - Mechanical Q 5.59 Qes - Electrical Q 0.37 Qts - Total Q 0.36 Vas - Equivalent volume 210 litres Xmax - Maximum excursion 15 mm Sd - Cone Area 1029.2 sq cm Ah...just read several old threads. Didn't realize people have already used these in a car. Great. So I'll put both in a sealed 7 cu ft box and wire it for 2 ohm! [/QUOTE]
