If you read the other questions, the connection is explained. Any 4 RCA sources to one Amp or reversed such as single CD player to 4 different amps. **Q: Will this work for car audio?** A: I don't see why it wouldn't. **Q: What is the maximum recommended cable length for the output, since it is passive?** A: That’s hard to tell. Depends on your cable and your tolerance of signal degradation. ## Customer Reviews ### ⭐ Selecteur de sources *by V***E on 11 August 2022* Une voie sur le sélecteur ne fonctionne pas surement un problème de câblage ou de soudure mal faite ### ⭐⭐⭐⭐⭐ 問題なし *by J***K on 25 September 2025* スイッチがスピーカー回路に入って音質が劣化することは無いようだ．スイッチの質感もよい． ### ⭐⭐⭐⭐⭐ Ottimo! *by O***I on 1 September 2025* Ottimo! ## Frequently Bought Together - SOLUPEAK ST42 4-Way RCA Audio Switch Source Signal Input switcher selector Splitter Box (4 in 2 Out) - Monoprice 1.5ft Premium 2 RCA Plug/2 RCA Plug M/M 22AWG Cable - Black - Tan QY 2RCA to 2RCA Cable 3Ft, Gold-Plated 2 RCA Male to 2 RCA Male Stereo Audio Cable for Home Theater, HDTV, Gaming Consoles, Hi-Fi Systems (3Ft/1M) --- ## 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.tn/products/485128473-st42-4-way-rca-audio-switch-source-signal-input-switcher](https://www.desertcart.tn/products/485128473-st42-4-way-rca-audio-switch-source-signal-input-switcher) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-09*
