Although it's true that factory sound systems have significantly improved in the last decade, they still leave much to be desired, especially for those of us who are used to high-dollar audio gear. This was also the case with our EcoBoost project truck, as its factory Ford speakers left much to be desired. However, we didn't want to tear up our dash to install a new head unit, so we called up the experts at MTX. They provided us with two sets of Thunder Axe component speakers, a TH90.4 four-channel amp, and a ThunderForm 10-inch underseat subwoofer. For wiring, we turned to Stinger, who supplied high-quality RCA cables, amp wiring, a power distribution box, and Stealth Roadkill sound-damping mat. We also chose this time to upgrade our battery to an Interstate MT7 AGM battery with 48-month free replacement. With all of our new goodies in the bed, we drove out to Audio Innovations, in Glendora, California, where their experienced techs put it all together. To see how these simple upgrades drastically improved our F-150's sound without changing the OEM head unit, read on.
