It does not have a bass, treble or loudness setting. It does have an equalizer with settings for Flat, Pop, Rock, Jazz and Classical. If the a system has decent fidelity, you won't need any of these things to make it sound good. A true High Fidelity system sounds fine without them. I've tried all the equalizer settings, turning it off (Flat mode) sounds great. At 20W per channel and 40W for the sub-woofer, you get enough power without the amplifiers getting saturated and clipping. Note, your average car stereo is 8 - 12 watts per channel. This should give you a sound density comparison.
