These speakers ship as two pairs and deliver a combined 800W maximum output with 200W RMS per pair, so the single biggest reason to buy is the jump in loud, clear playback and pronounced highs for a modest budget install. They are best for everyday drivers and DIY installers who want clearer vocals and treble detail from factory head units.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower handling:\u003c\/strong\u003e 400W maximum per pair with 200W RMS lets the speakers play loud enough for typical in-car listening without immediate need for an external amp.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-way design:\u003c\/strong\u003e The combination of Mylar dome midranges and dome tweeters provides clearer high-frequency detail and improved vocal presence compared with basic two-way coaxials.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable construction:\u003c\/strong\u003e Poly-injection woofer cones, rubber surrounds and stamped steel baskets are built to hold up to regular automotive use and maintain sound over time.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation-ready:\u003c\/strong\u003e The set includes installation hardware and fits common door and dash openings with a 2.25 in mounting depth and 5.63 in mounting diameter.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide frequency response:\u003c\/strong\u003e A 65 Hz to 20 kHz response range covers most of the audible spectrum for balanced mid and high reproduction.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThese speakers are aimed at drivers who want to replace worn factory speakers with a budget-friendly upgrade that improves clarity and loudness.
