The amplifier of a car radio (standard equipment or purchased subsequently) very quickly admits its limits in terms of power and dynamism. At high sound levels, it quickly goes into saturation and spoils the musical pleasure. To compensate for this lack and allow your speakers to express themselves fully, the Impulse 4.320 is the ideal solution. It will boost your installation without the need for complicated assembly. Semi “Plug and play”, the Impulse 4.320 is a 4-channel digital micro amp, delivering 4 x 55 Watts. The Impulse 4.320 perfectly complements the Focal Integration speakers.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 class=\"text-fluid-xl relative font-bold uppercase mb-1\"\u003eFocal Inside\u003c\/h2\u003e\n\u003ch3 class=\"subtitle mb-5 relative font-medium text-lg lg:text-xl\"\u003eThe perfect sound for your vehicle\u003c\/h3\u003e\n\u003cdiv class=\"relative wysiwyg-content\"\u003e\n\u003cp\u003eWith more than 50 brands and 1,000 vehicle models covered, the Focal Inside range offers tailor-made configurations ensuring perfect compatibility.\u003c\/p\u003e\n\u003cp\u003eReplace your vehicle’s audio system easily without modifying the interior by choosing a Plug \u0026amp; Play hi‑fi solution.\u003c\/p\u003e\n\u003cp\u003eAdd amplification and subwoofers for a richer sound experience and impactful bass.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"7\"\u003eWhy the Focal Inside Impulse 4.320 is the Micro-Amplifier Benchmark:\u003c\/h3\u003e\n\u003cp data-path-to-node=\"8,0,0\"\u003e\u003cb data-path-to-node=\"8,0,0\" data-index-in-node=\"0\"\u003eMicroscopic Footprint \u0026amp; Hidden Mounting:\u003c\/b\u003e This is the primary \u003cb data-path-to-node=\"8,0,0\" data-index-in-node=\"61\"\u003e\"Information Gain.\"\u003c\/b\u003e Measuring an incredibly slim \u003cb data-path-to-node=\"8,0,0\" data-index-in-node=\"110\"\u003e6-15\/16\" x 1-7\/8\" x 2-5\/8\"\u003c\/b\u003e, this amplifier completely bypasses the need to run thick power cables down to your trunk or beneath the seats.
