The BOSS Audio Systems P65.4C Phantom speakers suit drivers upgrading factory door speakers who want clearer highs, better midrange definition, and a tougher mechanical build without committing to component speaker systems. They are a practical choice for owners seeking affordable, plug-and-play improvement with the option to add an amplifier later for greater volume and fidelity. If you need slightly more low-end extension or prefer separate component crossovers, consider a component kit; otherwise, these coaxial 4-way speakers are a strong all-around upgrade for daily driving and casual listening.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Are these speakers sold as a pair?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, the P65.4C Phantom speakers are sold in matched pairs for left and right door installation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do I need an amplifier to use these speakers?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No, they work with factory head units, but an external amplifier improves headroom and reduces distortion at high volumes.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"BOSS Audio Systems","offers":[{"title":"Default Title","offer_id":48423690862749,"sku":"B0032FOKRY","price":63.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/9596\/1757\/files\/boss-p65.4c-front-view.jpg?v=1781365309","url":"https:\/\/nexoltic.com\/products\/boss-audio-systems-p65-4c-6-5-4-way-car-door-speakers","provider":"Nexoltic","version":"1.0","type":"link"}
