The Memphis Audio NANO10SPX is one of the more impressive powered under-seat subwoofers currently available because it combines a compact low-profile design, weatherproof construction, and surprisingly strong output for its size. It’s essentially a ruggedized version of Memphis’s NanoBoxx platform built for trucks, Jeeps, UTVs, and powersports applications.
