How the list was built. Kicker, JL Audio, Audison, MSC, Rockford Fosgate, Cicada Audio, Audio Dynamics, Alpine, Kenwood, Stinger, Focal, Gladen/Mosconi, Wavtech, Musway, Sundown and DD Audio dealer lists and the MESA member list were merged (Kicker's 9 repeat listings and Rockford's 2 repeat listings removed first). A location counts as the same dealer across brands when the street number and street match in the same ZIP or city, or when the dealer name matches in the same ZIP. Matches where the address or the listed name differs are flagged in the Match column so they can be confirmed with a call. Arc Audio dealers come from arcaudio.com's dealer locator (Oct 15, 2026) and are ringed in red; "Lines" counts Arc along with the other fifteen brands and MESA membership. Sundown Audio's locator (Oct 18, 2026) supplied 174 U.S. locations after dropping its overseas and blank listings. Musway USA's locator (Oct 18, 2026) supplied all 146 of its listed locations with exact map pins; it lists no phones. The Wavtech list is partial: 222 dealers read from Wavtech locator searches around 64 metros (Oct 17, 2026), so a shop missing Wavtech may still carry it. Focal America's locator (Oct 16, 2026) supplied 702 U.S. locations with addresses, phones and the Focal Display / Powered by Naim / MECP flags shown in the details. Gladen Audio / Mosconi's locator (Oct 16, 2026) supplied 264 locations tagged by line (Mosconi only, Gladen only, or both), shown in the details. MESA (Mobile Electronics Specialists of America) is a dealer buying group, not a brand: its locator (Oct 15, 2026) listed 313 member shops, and membership is shown as its own chip and counted in Lines because it marks a committed specialist retailer. Stinger's dealer locator (Oct 15, 2026) supplied street addresses, phones and emails for 751 locations after removing repeat listings; many Stinger entries use the shop's legal or billing name, which shows in the Match column where it differs from the storefront name. Kenwood's independent dealer list (Oct 15, 2026) supplied street addresses and phones. Alpine's independent dealer list (Oct 15, 2026) supplied street addresses, contact names and emails; its "Style Center" and upfitter tags show in the details. Audio Dynamics dealers come from adcaraudio.com's locator (Oct 15, 2026) and include the owner or contact name where the locator gave one. Target rank is for shops not on Arc yet: it adds points for premium lines carried (Audison, JL Audio, MSC, Audio Dynamics, Alpine), Kicker Q Class, Rockford Power Certified, three or more lines, an email on file and open territory, and takes points off when an Arc dealer is within 5 miles. The Excel file shows the points behind every rank. The Cicada Audio list has no street addresses, so its dealers were matched by phone number or by name in the same city or ZIP; Cicada-only locations show no street.

Map positions are placed at the ZIP code center, so dots show the area, not the exact storefront. Kicker's top dealer tier ("Q Class") and Rockford's "Power Certified" designation are shown in their tier columns, along with the marine and powersports lines each brand lists. Email and website come from the MSC and Rockford Fosgate lists, plus emails found by web research in October 2026 for 1,068 more dealers (the Excel file shows where each one came from and flags the ones to verify). Instagram, Facebook and YouTube links were pulled from the shop websites of the top-ranked targets. Best Buy's 957 U.S. stores are shown as yellow squares; each dealer's distance to the nearest one is in the details and the table, so you can find the independents that sit in a Best Buy's shadow.
