If you don't necessarily want to install huge subwoofer enclosures with separate amplifiers in the trunk, but in the end small active under-seat subwoofers do not generate enough bass for you, then you have found the best compromise with the GTI800A system: with a very small footprint it needs not much space in the trunk and thanks to the larger interior volume it is convincing with a stunning bass performance.


A powerful 20 cm (8 “) woofer draws from the full thanks to a well equipped 200 Watts RMS Class A/B amplifier and ensures dynamic and deep basses. In addition to the RCA inputs, the laterally integrated amplifier also has high-level inputs that have been equipped with an automatic turn-on function. This means that car radios that only have speaker outputs can also be connected. Thanks to the extra equipment, the system is particularly well suited for retrofitting if there are no RCA or turn-on signal wires at the factory radio.


The high-quality housing, made entirely of MDF, impresses with its heavy weight as soon as you lift it. The front baffle is double reinforced, so that the woofer could be flush-mounted. Permanently high levels are no problem for the GTI800A: the surround was also double-stitched to the cone. The compact design with bicolour carpet, elegantly embroidered logo and chrome protection bars is visually striking.
