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

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.

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

Installed for a month no issue

This low converter works very well. The price point is nice. It's very simple to install. As stated by others it's extremely important to make sure you have your speaker polarity correct! Also, the instructions fail to mention that the 12v power source needs to be wired to an accessory feed (one that turns on and off with the ignition switch). Otherwise the converter will be on always. This is especially important if you plan to use the converters blue wire to trigger your amp! Because if the converter is always on, so is your amp = dead battery. Other than that, no complaints, but that wiring detail cost the product one star off my review.

Fits well. Durability noise level design. Ideal design. Thank you so much. We'll buy another one. Will recommend to whom that needs

Father in law approves

Burnt up in 5 minutes. Car filled with smoke

Easy to wire in. Worked well as intended. Would buy again.

Easy install, works great so far

Worked great in my 2015ford f250 xlt I wired them into the rear door speakers just behind my stereo and then ran them to my amp and it worked great

Too confusing for me. They recommend a multimeter to set up properly. Did not end up working out. The instructions were a little vague. Returned.

I wired the converter in to the car as per the instructions and it didn’t turn on. I have checked the wiring and the plug for the converter has power but it does not power on??????????
