We can add a subwoofer to any factory system. Factory sound systems rarely provide the dramatic and high quality bass range that comes from having an aftermarket subwoofer. In most factory systems you're literally missing a large portion of what the artist recorded. The powerful hit from a kick drum, the low 50hz warmth of a bass guitar, the ultra low frequencies in electronic music, all are completely missing without a subwoofer. Safe & Sound Mobile Electronics has a huge selection of loaded subwoofer enclosures, raw woofers, vehicle specific and empty enclosures of every possible size and configuration but our specialty is custom fabricated enclosures that look and fit like they came with the vehicle.
