Our take on the dBcomp5

The Rockville dBcomp5 is a five-channel car amplifier that powers four speakers plus a subwoofer from one chassis. It is aimed at drivers who want a single amp to run a full system without adding a separate sub amp. Its class D sub channel and built-in crossover make it more flexible than basic four-channel amps, though it sits in the budget tier rather than against premium brands. Owners rate it highly for value and output, while some note that its rated power is optimistic and that setup takes care.
