A quick upgrade that transforms everyday listening. Mount it in a compatible factory or aftermarket location, wire it to your head unit or an amplifier, and use the included or appropriate hardware. Adding even modest amplification helps these speakers reach their full potential. Even a few hours of playtime helps new speakers settle into their best sound. Even a modest amplifier transforms aftermarket speakers, giving them the headroom to play cleanly at volume. Sound deadening on the doors is an easy companion upgrade that makes any speaker sound tighter and fuller. A small external amp gives coaxial speakers the control they lack on head-unit power. Crossing over to a subwoofer keeps distortion low by relieving the speakers of deep bass. Foam baffles behind the speaker protect it from door moisture and tighten midbass. Upgrading the front stage first usually gives the biggest jump in everyday sound. A gentle EQ tweak can smooth any harshness once the speakers are broken in. Matching left and right levels keeps vocals centered on the soundstage. Speaker adapters and harnesses make for a cleaner, reversible factory install.
