Just two naked wires to connect to a passive subwoofer?** A: Although I am not using this it is a single speaker output to a 4 ohm subwoofer. **Q: Question for manufacturer: Does this take a stereo input to create mono output from the combined sources or do I need to feed it a mono source?** A: Hi, I used this to turn a passive subwoofer into an active one for my A/v receiver, taking a mono cable to the sub out on the receiver, I then connected the twin speaker cables to the two audio out on the mini amp **Q: HI. Does the amp contain a crossover or filter - so that full range sound can be applied to the inputs but only bass sound is passed through the amp ?** A: Yes, that’s exactly what it does. I feed it directly from the headset output from my laptop, and have it hooked up to a normal speaker which due to the output from the amp only being the bass frequencies now works as a sub. Works surprisingly well tbh. ## Frequently Bought Together - DollaTek 100W Mini Subwoofer Power Amplifier TPA3116D2 Audio HiFi Amp Black - 24V 6A DC Power Supply Adapter AC 100V~240V to DC 24 Volt 6 Amp 144W Converter Transformer 5.5x2.1mm Plug for LED Strip Light 3D Printer LED Driver LCD Monitor,Wireless Router,Security Cameras - kenable 3.5mm Mono Jack Plug To Single RCA Phono Plug Cable 3m Gold [3 metres] --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/173724302-dollatek-100w-mini-subwoofer-power-amplifier-tpa3116d2-audio-hifi-amp](https://www.desertcart.co.za/products/173724302-dollatek-100w-mini-subwoofer-power-amplifier-tpa3116d2-audio-hifi-amp) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-11-15*
