A pair of 10 inch JL Audio W3-series subwoofers went into a custom-built box. Although the space was very tight, our master technician Sam Lynch managed, yet again, to produce a perfect fit enclosure with the right amount of airspace. We also installed a 5 channel amplifier by Kenwood to power up the subs and the pre-existing aftermarket speakers. This King Ranch jams like no other! Customers were asking where all this bass was coming from! Stealth-mode!
