Reviews: Their solution is the 4000-watt OPTI 4000D...The OPTI 4000D is a single-channel limited-bandwidth Class D subwoofer amplifier...The OPTI 4000D RCA's can accept from 200 mV to 8 Vrms...The owner's manual provided most of the necessary information for installing the OPTI 4000D amplifier...Sound quality of the amplifier was quite good...
Retrevo's Recommendation: Buy with caution if you really want it
