It is probably my fault but I wouldn't know without the tech info. ### ⭐⭐⭐ 3.0 out of 5 stars Check input requirements *by P***N on Reviewed in the United States on December 2, 2014* Reading the first review, it occurred to me that these are 70v speakers, designed and wired for multiple speaker hookup. It would require an amplifier with 70v output to make them work. However, if you can get inside the unit you could bypass the transformer and wire directly to the speakers. I like them for size and style, but I'll need to purchase one to see if they can be reconfigured for standard 8 ohm input. 4" and 8" plus black gives them versatility. ## Frequently Bought Together - CERTIFEID One Piece 4" All-Weather 2-Way Speaker, Bookshelf/Wall-Mount/Corner-Mount, 8 Ohm/70V Commercial Indoor/Outdoor, White (OS-A402WH) - Google Chromecast - Streaming Device with HDMI Cable - Stream Shows, Music, Photos, and Sports from Your Phone to Your TV with Extra Cable- Charcoal - Mounting Dream TV Wall Mount for 32-65 Inch TV, TV Mount with Swivel and Tilt, Full Motion TV Bracket with Articulating Dual Arms, Fits 16inch Studs, Max VESA 400X400 mm, 99lbs, MD2380 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/11289736-one-piece-4-all-weather-2-way-speaker-bookshelf-wall](https://www.desertcart.it/products/11289736-one-piece-4-all-weather-2-way-speaker-bookshelf-wall) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-09*
