## Description

desertcart.com: NuIth Car Audio Speaker Wire to RCA Line Output Converter, 2-Channel High to Low RCA Converter for Adding Amplifier Subwoofer to Stock Stereo : Electronics

Review: Used on My ’07 Avalon – Perfect for Aftermarket Radio Install - used this NuIth RCA line output converter to install an aftermarket radio and subwoofer in my 2007 Toyota Avalon, and it worked perfectly. It was exactly what I needed to get a clean RCA signal from the factory speaker wires. The wiring was simple — just tap into the speaker lines and connect your amp RCA cables. It’s compact, solidly built, and the signal came through clean with no noise, buzzing, or distortion. It made adding an amp super easy without needing to completely redo the wiring or rip out the stock harness. For the price, this is a great little tool to have if you’re adding a sub or amp to a stock or aftermarket system without RCA outs. ⸻ 🔧 Pros: • Clean signal output — no interference • Easy to install — wiring is straightforward • Great for factory or aftermarket radio setups • Worked perfectly on my 2007 Avalon • Compact and well-built Cons: • Doesn’t come with wiring instructions (but easy if you’ve done installs before) ⸻ Final Verdict: If you’re upgrading your sound system and need RCA outs from speaker wires, this converter does the job right. I’d definitely use it again — highly recommended for any DIY car audio setup.
Review: Works perfect - No complaints here... Works as it should... Have it connected to a 2024 Chevy equinox with a Kicker 15 Solobaric and kicker 1,000 watt amp... It does stay on a few mins after car is off, but that's because the acc stays on about a min after car is off
