Thanks to modern ADC (Advanced D-Class) technology, it combines high output power with excellent efficiency and a compact design. This makes the power amplifier ideal for vehicles with limited installation space, such as under seats, in motorcycles, or behind seats in vans\u003cspan aria-hidden=\"true\" class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e.\u003c\/p\u003e\n\u003cp data-start=\"540\" data-end=\"1190\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eThe rugged, IP55-certified aluminum housing reliably protects the electronics from moisture, dust, and external influences. Sealed connectors and the fanless design prevent the ingress of dirt and ensure high long-term reliability. With flexible high- and low-pass filters, bass boost, and high-level and RCA inputs, the amplifier can be easily integrated into virtually any audio system. The integrated USS (Universal Speaker Simulator) technology also ensures compatibility with modern factory-installed radios that use speaker recognition\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=\"1192\" data-end=\"1212\"\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=\"1214\" data-end=\"2080\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e\n\u003cli data-section-id=\"1f9iz7\" data-start=\"1214\" data-end=\"1242\" style=\"font-weight: bold;
