CubiluxAS-R1 4-Way Audio Splitter Box - 4-Channel Stereo RCA Splitter - Aluminum Alloy (1 in 4 Out)

I bought this to split the stereo rca’s coming from my car head unit because I didn’t want to remove it, which requires removing a bunch of dash pieces, risking damage. I split the signal to a self powered subwoofer.It works flawlessly with no sound degradation or interference, and it’s future proof if I want to add other amplifiers or self powered speakers at a later time.

Works great have used in multiple audio installs that I’ve done, never gave me any issues.

Excellent RCA audio splitter! This little splitter is fantastic. It is built extremely well and the connections are very snug and secure. What I love is that this is a true splitter: 1 signal in and you have 4 simultaneous signals out (or visa versa). My audio signals are completely quiet out of this device, with no detectable loss in audio quality. I love this splitter!

Works as it should. Seems to be made with good quality

Over all tight fit and looks clean

I was looking for an adaptor that would enable me to play two subwoofers that were connected to a single sub out on my Wiim ultra and it worked perfectly. It was easy to install and use!

Got it fast and works great

I'm glad I was able find this device. It feels pretty heavy duty and seems to push out the signal nicely to all devices. Most AV's are switches, this is just forwarding your signal on. It doesn't need a power supply which AV boxes usually don't so you can stick it anywhere.The only thing that would make it better would be a mounting kit to mount it on the back of furniture or something. For now, 3M double sided tape will do.
