2011 Subaru Outback Dual fuse holders were used to accommodate the two power wires. Our technician’s pre-wired the speakers for easy future servicing. To maximize the output of the midbass driver we treated the door with SoundSkins sound damping material. The rear speakers were upgraded with Audiofrog 4″ midranges. Custom ABS adapters were machined to hold the Audiofrog midrange in the factory location. Thanks to the thin design of the JL Audio Tw3 woofer, this enclosure can fit in the factory storage bin. The low profile of the Arc Audio amplifiers allows them to be installed under the factory floor. The Helix processor was mounted under the driver’s seat so the client could easily access it for tuning. With the factory trim pieces in place our work is completely invisible.
