One of our existing clients from Tigard, OR, contacted Kingpin Car and Marine Audio to let us know he had purchased a 2017 Toyota Rav4 and wanted to transfer his existing stereo into the new car. We scheduled a consultation with the client to review what we could build in the new vehicle and how it would look. With his approval, we booked an appointment to start work on his new Rav4 stereo system.
All the systems we design are fully active. An active system means that we use a Digital Signal Processor (DSP) to divide the audio signal and send tweeter, midrange and bass information to dedicated amplifier channels. Active systems give us complete control over crossover frequency, speaker output level, equalization and signal delay. The result is an audio system with amazing clarity, focus, detail and accuracy.
Front Stage Configuration
For the front speakers in the RAV 4, we used the woofer and tweeter from a Hertz HSK165 component set. We mounted the woofers in the factory locations in the front doors and mounted the tweeters higher to raise the soundstage height. We used the client’s Hertz HDP4 amplifier to power the front speakers. The HDP4 can produce up to 150 watts per channel – more than enough to power the 6.5-inch woofer and 1-inch tweeter.
The client wanted something “out of the way” regarding a subwoofer solution. To achieve this goal, we created a custom fiberglass enclosure in the right-hand side corner of the trunk. We applied several layers of 3M masking tape to the body panels and then laid down layers of fiberglass matting. Some shops try to build enclosures like this out of wood, but we use fiberglass to maximize the enclosure volume and minimize weight.
We created a front for the enclosure and included an MDF mounting ring for a Hertz DS30.3 12-inch subwoofer.
With the front panel blended into the back, we wrapped the enclosure in dark-gray carpet to match the vehicle interior and installed a protective grille.
Toyota RAV4 Stereo Tuning
With the installation complete, we started to set up and optimize the audio system with our Audison bit Tune and an oscilloscope. We set each amplifier for maximum performance without distortion. The Audison bit Tune helps us configure speaker output levels and signal delay settings for the Audison bit TenD processor in the vehicle.
Once the project was complete, the client returned to Kingpin Car and Marine Audio in Wilsonville, OR. He loved the way the system sounded. He was thrilled with the subwoofer enclosure and the fact that he could still use all the cargo space in his vehicle.
