Review on 8 Inch Blue Injection Molded Cone Car Vehicle Subwoofer Audio Speaker - Chrome-Plated Steel Basket, Dual Voice Coil, 4 Ohm Impedance, 600 Watt Power - Pyle PLBW84 for Improved Vehicle Stereo Sound System by Michael Swanson

This is a great replacement for factory systems, but it won't handle the wattage it's advertised on. This subwoofer was meant to replace an old 8" radio shed, 50W RMS, 100W max. Less than a month later it died and the RS speaker is back. The first night I installed Pyle it kind of smelled. Then the rubbing the voice coil. Less than a month later me and a friend decided to see how much power was going into it and it died. Only about 200 watts in 30 seconds. Sad day no we're almost 600 watts!
