Naglagay ako dati sa E36 ng SAS 10" powered Bazooka mahina ang dating ng bass sa cabin. Ginawa ko na lang I cut the metal behind the center armrest and installed a 12" free air subwoofer, bass sound is better now inside the cabin.
mga bros:
ndi lahat ng bazooka systems mahina. SAS bazooka is a good brand but expensive. try JBL new model bazooka. louder tha SAS yet cheaper. drop by my shop to see actual unit.
i have one of those pioneer bazooka with built-in amplifier 10"subs installed in my corolla... sounds great naman... pang kumpleto lang ng sound! at least di ka bitin gaano sa bass sound compared to full coax set of speakers lang ang gamit mo =)
