The legendary QUANTUM Q202A active underseat subwoofer gets a worthy successor with the new and improved Q208A. The compact dimensions have remained so that it can continue to find its place under many vehicle seats. With an impressive 150 watts RMS, the integrated Class A/B amplifier has a whopping 50% more power than the previous model. Important features such as the Auto Turn-On Function and the high level input have been adopted to enable integration into modern factory sound systems, even if there is no remote turn-on line and no preamplifier signal via RCA. The passive woofers installed on both sides are newly developments, which are protected with robust metal covers and give the housing its own unique look. This is rounded off by a discreetly stamped ESX logo in the protection grille of the woofer, which provides additional stability.


Thanks to extensive features such as phase switch and low pass crossover, the powerful bass sound can be optimally adapted to the vehicle acoustics. Of course, the Q208A also has a remote controller via cable to adjust the bass level. Although the height of the housing is very low, there is still room for two oval passive woofers on both sides. As a result, the actively driven subwoofer is supported by the passive resonance, especially at low frequencies, and a richer bass foundation is generated by more air displacement.
