The owner of the brand new 2009 Lexus RX350 wanted to have more bass on his car. This car comes fully equipment and has Mark Levinson sound system installed. In my opinion, I enjoyed the stock system. It has very balanced, natural sound and very good sound stage too and I often found myself just enjoying the music and not listening to its flaws. The only thing that it’s lacking is indeed the bass performance. The RX350 has very big space inside that a small subwoofer at the back is not going be enough to fill the whole car with good bass. So all we did is to concentrate the bass performance

This install is a simple setup: one Alpine PDX-1.600 600w RMS amplifier with two Alpine shallow mount type S subwoofer and a 10 farad Capacitor to ensure good power supply to the amp. I have also used Rattle Trap from Fatmat as sound deadening material where the subwoofer is located to minimize vibrations to the car. Since the stock amplifier is conveniently located beside the spare tire storage area, I am able to tap into the signal from there and keep the signal run as short as possible. One thing I did differently is I used one channel of signal from front woofer and another from the stock subwoofer output. By doing this I was able to increase not only the deep bass but also some upper base to give it a more impact type of sound.
