JL Audio 10" Basswedge vs 10" Microsub

The bass wedge will be more efficient due to the ported box design compared to the JL Microsub used by the same amplifier.  It comes down to your preference of accommodating either subwoofer box in your vehicle. Personally, I would settle for the Bass wedge since you have a 4 runner.  The micro subwoofer would be more suited to a sedan or hatchback being a smaller distance from the driver to trunk area where the subwoofer is placed.  if you place the subwoofer facing the cars body panel (placed facing the side if you opened your trunk area, then you will have extra DB's due to cabin gain transfer.   However, I rather you do your own experiments with the dedicated subwoofer box you wish to run in your car.  You can always borrow a mates box to trial in your vehicle against the Bass wedge.  The micro sub is a sealed enclosure so its always good to trial a sealed vs ported box.  Another factor is the JL Bass wedge have newer driver with a higher wattage compared to the old JL Microsub which was rated at 300watts peak. The bass Wedge is rated at 300RMS so again, with power amps being cheaper today, the Bass Wedge will serve you a long time as long as you respect your audio gear and turn it down when you hear distortion.  Hope this helps you out mate!
