Carrera 4s: Porsche SQ Audio upgrade Leave a Comment / Audio, Custom Fabrication / By Ultra Auto Sound In Canada we need good tunes winter or summer! Kenwood deck originally installed to test quality, then later upgraded to a double din for cosmetic purposes. Double din in a porsche is meant to be! Upgrade speakers, amplifier, head unit, and add subwoofers Rewired the oem bose amplifier. Ran power for the new JL Audio XD series amplifier. Removed the bose speakers and replaced it with Focal K2 Power components. 100KRS. Built a low profile enclosure for two JL Audio 8W3v3 sub woofers. Just fits. Enclosure mounted inside the vehicle behind rear seats. Does not waste any space. Looks original! Bass bounces off the rear glass into the cabin. No rattle! Sounds tight!
