Thanks to its exceptionally compact housing, the power amplifier can be installed almost invisibly and is ideal for retrofits, factory-installed radios, and modern plug-and-play applications. Automatic power-on functions, high-level inputs, and extensive filter options enable easy integration into existing audio systems. The efficient IC amplifier technology ensures clean sound and reliable power output\u003c\/strong\u003e\u003c\/span\u003e.\u003cbr\u003e\u003cbr\u003e \u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003e\u003cspan data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-section-id=\"vdeyho\" data-start=\"760\" data-end=\"780\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003e\u003cspan style=\"text-decoration: underline;\"\u003eTechnical Specifications:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul data-start=\"782\" data-end=\"1548\"\u003e\n\u003cli data-section-id=\"1gm1v5f\" data-start=\"782\" data-end=\"805\" style=\"font-weight: bold;
