PBX, Selenium, Soundigital, Taramps, and Spaudio Subwoofer Sound System

I assembled this sound system from scratch. It was built similarly to American-style systems, with heavy emphasis on sub-bass. It is performing exceptionally well. Feel free to test it! It was installed inside my vehicle, specifically in the rear seats, due to its size. Includes: 2× 15-inch PowerBassXTreme (PBX) subwoofers, imported, 2000W RMS; 1× JBL Selenium DX250 Trio (including included Selenium horn); 2× SPTW-27 Super Tweeters, 150W RMS, for high frequencies; 1× Soundigital 3000.1 NANO amplifier; 1× Bass knob; 1× Taramps TS 400.4 amplifier; Complete wiring; 1× Bluetooth system; 1× Enclosure (matte black), custom-built for these subwoofers, featuring internally threaded rods to minimize vibration and deliver smoother, deeper bass (tuned to 35 Hz); includes a port extension rail if more sub-bass is desired; 1× Circuit breaker (for power on/off); 1× Voltmeter; 4× Italian 12V 100Ah batteries for amplifier power supply; 1× Battery charger, in case you prefer not to modify your car’s alternator to charge the batteries; I offer installation of this system in your vehicle for an additional €30. I have more photos and videos, but OLX itself prevents me from uploading all of them. If you’d like to see them, please send me a message!
