This is a drop in replacement for a Pioneer Design 8 Ohm Woofer, Mavin's Own 12" High Performance Driver
Simple process to replace any of the standard Pioneer 12" Woofers, just undo the screws pop out the old woofer, disconnect the wires and do the reverse to complete the install.
In 5 minutes you're done, still better, that dead sounding Pioneer will burst back to life with performance once again like that of a factory New Sub.
