The X303-4 carries a High-Res Audio certification so you can be sure all your favorite tunes will sound their best.
The amp accepts input signals via RCA cables from an aftermarket receiver or by way of a factory radio’s speaker wiring so it’ll work with almost any non-premium mobile audio system. If you do use the speaker-level inputs, the amp can sense the signal and turn itself on, so you won’t need to install a separate remote turn-on lead running from the receiver or fuse box.
