Wanted: 2004 4runner rear compartment 8" Subwoofer. It is part of a JBL ten speaker sound system. It's actually smaller than 8", more like 7 1/2". It is a Dual Voice Coil type at 1.2 ohm impedance each according to info I have found. It is a shallow mount style, approx 3" mounting depth. There are no aftermarket replacements available that I have found. I have read about 4runner owners replacing the JBL Sytem for something better. I need to contact one of them to buy their old JBL Subwoofer as someone stole mine..... Appreciate any help on this problem.. Thanks, Waltham III.
