Passive suboofer?** A: A Passive subwoofer would be my recommendation, the passive subwoofer depends on an external amplifier and this would be the external amp. If you use an Active subwoofer; it contains a built-in amplifier and the result would be overpowering the subwoofer and you will get adverse effects **Q: Does the amp have a fuse?** A: Your question does Not specify your concern for a fuse on the Power input or on the Speaker Output section ? Answer: No fuse at all, the circuit with a 12 VDC 2 amp or above 18~24 VDC Power supply adapter does not get warm at all; it has a very good Audio quality response as well as the Output Power volume for its size. It is an excellent amplifier. with 12VDC supply - 15Watt Output Power up to 24VDC supply - 50Watt Output Speakers Power and the Subwoofer power Output ranges from 20W ~ 100W output Power depending on the Power supply input. **Q: how high does the subwoofer lowpass go? Can i push it up to around 500hz, or does it stop at, say, 150hz?** A: It can't 500hz, only be used in the range of 20-200hz. **Q: Are the main L&R speakers full-range or high-passed? If they are high passed what is the cutoff frequency?** A: Both channels are full range, with separate bass/treble controls. I don't know what frequency the controls are biased at. ## Frequently Bought Together - MakerHawk Bluetooth Amplifier Board HiFi Stereo 2.1 TPA3116D2 2X50W+100W 12V-24V Audio Power Amplifier Module Bass and Treble Control for Store Home Theater Speakers (ZK-TB21) - AICARS Mini Audio Amplifier Car Audio 2 Channel Amplifier Hi-Fi Mini Stereo Receiver Amp with DC 12V-15V 40W for Cars Motorcycles Computer Speakers - Antrader JF-Z05 DC 12V 2. 5A Magnetic Solenoid 45N 15 mm Push Open Frame Electromagnet --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/226280448-bluetooth-amplifier-board-hifi-stereo-2-1-tpa3116d2-2x50w-100w](https://www.desertcart.gr/products/226280448-bluetooth-amplifier-board-hifi-stereo-2-1-tpa3116d2-2x50w-100w) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-31*
