Features a mode switcher that allows you to conveniently switch between SUB mode and PBLT mode. Equipped with 19V 4.74A high quality power supply - Applications: 1. G2 can be used as a passive subwoofer power amplifier; 2. G2 can drive a single channel as a mono amplifier. Use two G2 to separate the left and right channels known as PBLT/BTL bridge amplifiers. Compared to normal 2.0CH Amps, there is absolutely no interference between two channels, which can provide more power - 4 output level settings (20/26/32/36dB). It can maintain the purity of the sound and avoid the effect of the resistor. In addition, there is a bass cut-off frequency control knob - Adopting TI TPA3116 and NE5532 operational amplifier, it provides 100W high power and can drive most household sub-speakers and mono speakers. Optimized circuitry eliminates any background noise at all. It also has a built-in speaker protection circuit and low pass bus filter - Prompt and prompt customer service.

Says NOTHING of how loud it will play, or how good it sounds. Again, power rating DOES NOT DEFINE A PRODUCT. **Q: Why are there left and right inputs for a mono amp? If you have a mono source, can you plug it into only one input, or do you have to connect to both?** A: Hello. We have a using guide picture in the listing. You can check that. We have left and right inputs since some customers using stereo signal. If yours are mono, just connect one input. **Q: When using in sub mode, which rca input to plug in? left or right or both?** A: Hello. Please see our second main image. The "audio in" rca posts are connected to sound sources. The "spk out" posts are a set of speaker binding posts. When in sub mode, you need to connect your passive subwoofer with bare wire or banana plug. If you still have questions, you can send your device models and images to nobsound@doukaudio.com. We will help you with it. **Q: When using this with a subwoofer how do I know where to set the frequency cortrol knob?** A: Like others have said, turn volume up on your main speakers (L/R) to desired listening level then advance frequency crossover knob until you can hear the subwoofer in your favorite music passage, then back the sub down until it is un-noticeable in the passage. Your subwoofer range should take over at the effective L/R low frequency cutoff point...Blend it in seamlessly. ## Customer Reviews ### ⭐⭐⭐⭐⭐ ボディソニック用振動ユニットの駆動アンプとして使いやすい。 *by 無***悩 on May 27, 2024* サブウーハーとの併用でButtkickerの重低音振動ユニットを以前から使用しており、 振動ユニットのみ単体のサブウーファー用アンプで駆動していましたが、 元ソースとして使用しているAVアンプのLFE（※低音域効果音チャンネル・通常は アクティブサブウーファーの駆動用に使用）ライン出力が低いのか、 ある映像ソースでは丁度いいのに別のソースでは目一杯ボリュームを上げても 殆ど反応しなかったりと今ひとつ安定せず、かといってAVアンプのLFEを弄ると 今度は全体的な音のバランスが崩れるという、どうにも決まらない状況でした。 こちらのサブウーファーアンプも基本仕様は元々使用していたものと殆ど一緒でしたが、 入力ソース側のゲイン調節が可能という点に惹かれて購入。デフォルトより１段低い 入力ゲインで設定したところ、従来のサブウーファーアンプでは殆ど反応しなかった 映像ソースで振動ユニットが反応し、元々が丁度よい映像ソースでも音量ボリュームの 可変範囲で調整可能と、まさに狙い通りの効果で上々の使い勝手です。 ## Frequently Bought Together - Nobsound G2 Subwoofer Power Amplifier Mini Mono SUB Amp 100W PBTL BTL Bridge Home Theater - Dayton Audio BST-1 High Power Pro Tactile Bass Shaker 50 Watts RMS, 4 Ohms Impedance - Turn Any Surface into a Speaker System - Generates Subwoofer Lows - Dayton Audio BST-2 Tactile Bass Shaker 35 Watt --- ## 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.kg/products/741772659-nobsound-g2-subwoofer-power-amplifier-mini-mono-sub-amplifier-100w](https://www.desertcart.kg/products/741772659-nobsound-g2-subwoofer-power-amplifier-mini-mono-sub-amplifier-100w) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-05-09*
