The Pyle Audio PLWB158 is a 15" car subwoofer from Pyle's Blue Wave Series. The subwoofer is designed with a non-pressed paper cone, chrome stamped basket, chrome magnet cover, and chrome gasket. It features a 2.5" high temperature voice coil with 8-ohms impedance to give 1000 watts of peak power handling. The only difference between the PLWB158 and Pyle's PLWB155 and PLWB15D is the impedance since the PLWB155 has single 4-ohms impedance while the PLWB15D has dual 4-ohms impedance.
