Introduction
This OEM Subaru stereo has a reasonably bright and useful 4.3" LCD display, Bluetooth audio and phone functions, HD radio, USB file playback, and iPod playback. The main audio processing IC is an SAF7741 by NXP, which provides high quality digital audio processing. However, the main "power" amp, a Toshiba TB2926HQ, limits the performance. [ … ] This guide provides instruction for adding line out signals, so that an external power amplifier and/or subwoofer can be used. [ … ] An optional step is the addition of components to boost the line out level by 8dB, which can improve the signal to noise ratio when an external DSP is used. [ … ] NOTE: The factory default equalization is horrendous! To remove it: with 'Audio Off' showing on the screen, hold down the '6' key, and rotate the 'Tune' knob until a 'Version' menu appears. Release the '6' key; then repeat this process twice, until the 'Factory Test Mode-3: Eq' menu appears. Select 'OFF'! Without this step, the line out signals would be near useless. [ … ] See the attached 'Mouser Part Numbers' document for the optional parts to order for the preamp. [ … ] This modification is not easy, but the results are worth it!
