The poor sounding factory car audio system in his 2018 Subaru WRX was making the owner crazy, so he came into our San Mateo location to find a solution. He had decided on keeping his factory radio so we used a Helix DSP MINI OEM integration processor with a 64-Bit DSP to fix the factory signal. In addition, the DSP MINI offers unique DSP features like Augmented Bass Processing, StageXpander and Real Center function, which open new possibilities to tweak an audio system. Powering the interior speakers is a Kenwood Excelon XR401-4 four channel amplifier. Both the Kenwood amp and Helix DSP were custom mounted on an ABS bracket under the passenger seat. The front doors now house the Blam 165RS component speakers and have had a Hushmat AE00010 treatment to cut rattle and road noise. The rear speakers were also replaced with a matching set of Blam 165RC coaxial speakers with a similar Hushmat treatment. To add the much-needed low-end fill to the car audio system, we installed the JL Audio ACP112LGTW1 single 12-inch TW1 sealed loaded subwoofer enclosure. This system was a perfect fit for the limited space in the WRX trunk. We again did a Hushmat AE0020 trunk sound deadening treatment. We then tuned the system on the laptop with Audiotec Fischer’s DSP PC-TOOL Version 4 along with the MTK 1 measurement toolkit. The result was a great sounding system, a quality build and a happy customer. The car audio installation was done by the professionals at Audio Express 1105 San Mateo N.E.
