The Ampere Audio AA-3.0 18″ was designed for 2000w rms per driver. The lead wires are formed into the spider layers which further enhances durability and eliminates lead slap\/breakage problems. The frame is cast aluminum with a sandblasted, powder coat finish. One of the thickest 3” coils on the motor reduces energy storage from inductance, with the side benefit of lowering distortion for “faster” response.\u003c\/b\u003e \u003cbr\u003e\u003cbr\u003e \u003cb\u003eAmpere Audio AA-3.0 18″ D4 Technical Specs\u003c\/b\u003e \u003cul\u003e \u003cli\u003e2000w RMS \u003c\/li\u003e\n\u003cli\u003eTriple stacked 1″ slugs \u003c\/li\u003e\n\u003cli\u003e4 layer 3″ aluminum coil \u003c\/li\u003e\n\u003cli\u003e3 Layer spider pack \u003c\/li\u003e\n\u003cli\u003eSewn leads \u003c\/li\u003e\n\u003cli\u003ePressed paper cone \u003c\/li\u003e\n\u003cli\u003eButyl rubber surround \u003c\/li\u003e\n\u003cli\u003eD2 or D4\u003c\/li\u003e\n\u003c\/ul\u003e \u003cb\u003eT\/S SPECS:\t\u003c\/b\u003e AA-3.0 18\" D2 \/ AA-3.0 18\" D4 \u003cul\u003e\n\u003cli\u003eRE (Ohms):\t4 \/\t6.8 \u003c\/li\u003e\n\u003cli\u003eFS (Hz):\t28.251 \/\t27.873 \u003c\/li\u003e\n\u003cli\u003eVAS (L):\t92.683 \/\t96.31 \u003c\/li\u003e\n\u003cli\u003eQes:\t1.017 \/\t1.171 \u003c\/li\u003e\n\u003cli\u003eQms:\t3.466 \/\t3.194 \u003c\/li\u003e\n\u003cli\u003eQts:\t0.786 \/\t0.857 \u003c\/li\u003e\n\u003cli\u003eBL (NA):\t20.8 \/\t23.9 \u003c\/li\u003e\n\u003cli\u003eMms (Grams):\t625.409 \/\t619.91 \u003c\/li\u003e\n\u003cli\u003eCms (MM\/N):\t50.746 \/\t52.732 \u003c\/li\u003e\n\u003cli\u003eSens (dB @ 1w\/1m):\t85 \/\t84.4\u003c\/li\u003e\n\u003c\/ul\u003e \u003cb\u003eEnclosure Specs:\u003c\/b\u003e\u003cul\u003e \u003cli\u003eSealed Enclosure:\tNot Recommended \u003c\/li\u003e\n\u003cli\u003ePorted Enclosure:\t5 cu ft \u003c\/li\u003e\n\u003cli\u003eRecommended Tuning:\t 32Hz \u003c\/li\u003e\n\u003cli\u003eRecommended Port Area:\t24 sq in \u003c\/li\u003e\n\u003cli\u003eDisplacement:\t0.21 cu ft \u003c\/li\u003e\n\u003cli\u003eDepth: 15.1\" \t \u003c\/li\u003e\n\u003cli\u003eOutside Diameter:\t18.5\" \u003c\/li\u003e\n\u003cli\u003eCut-Out:\t16.75\" \u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Ampere Audio","offers":[{"title":"Dual 2 Ohm","offer_id":49971811909871,"sku":"AA-3.0 18-D2","price":299.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/4518\/2959\/files\/AA-30-RVE-18-000__99080_4238a3a8-03ea-4604-b4cd-180a3c2b04db.png?v=1782352583","url":"https:\/\/1800woofers.com\/products\/ampere-audio-aa-3-0-rve-v-4-18-subwoofer","provider":"1800woofers.com's online car audio store | Authorized online dealer!","version":"1.0","type":"link"}
