Setup is simple with a GMRS Midland radio and factory stereo with AUX input. Issue was that every time I powered up the radio my factory system audio would drop with distortion then slowly come back after a minute and I could use both fine through the factory setup. When turning the radio off, the same drop and distortion would happen again. That is when it occurred to me that the Midland line-out is not headphone or line level, it is technically speaker out and labeled as such. I just did not notice. So I bought this SNI-35 and hooked it up. It did take care of the weird drop and distortion issues. Great! But when hooked up there is a MASSIVE drop in audio volume on the other aux input - again, I have the radio AND an aux input to my factory system - they aux port is factory and usually my phone is going to it. As soon as I unplug the RCA connections on the SNI, audio come way back up. Both adjustment pots are at max clockwise. Does not matter if the GMRS radio is on or not, it simply kills the other input levels. So be warned if you have a setup like mine, it will not work if you are going to an aux input with more than one source. Sadly. But I can not blame the product itself, so five stars since it technically does as it should. I will have to go with another solution.

Just what I needed to solve a line level conversion problem I had. I hooked it into the speaker wires coming from my Denon amp going to speakers in the back of the room by my drums. I connected the low level output to a miniature headphone amp I mounted on my drum kit. I control the media player on my HTPC from behind my drums. I can now practice songs and control the headphone volume from the little amp mounted on my kit so I can have the perfect balance of music from the speakers in the room, the headphones, and my drums. Perfect for learning new songs on the drums! Could not have done it with this line level converter. It produces a very good low level signal quality from the high level speaker output from the amp. I already bought another one for a similar project at my friend's house! A very good purchase decision! 05-January-2015 Comment update: I found out the hard way this product can not handle a lot of power. The input resistors (four 8 ohm 5 watt) got red hot and melted the plastic case from the output power of my Denon amp (~75 watts/channel). I replaced them with 8 ohm 50 watt resistors (physically much larger resistors). The new resistors are too big to fit in the plastic case which melted and is unusable anyway. It works fine now even with the high input power.

This is exactly what you need if you are hooking up an amplifier or powered sub-woofer to a head unit that does not already have sub-woofer RCA outputs. Sure you could tap and run speaker wire direct to most amps, or a powered sub-woofer in my case, but the sound quality is far superior through RCA cables. This LOC is dead simple to install and provides great sound quality. I installed the PAC LOC in a 2014 F-150 by tapping into the front speaker wires. In most vehicles you could tap into the rear speakers, which is usually closer to where an amop would be installed, but in my particular case, Ford attenuated the sound level to the rear speakers, which means I would not get full input to my powered sub at higher volumes. I installed the LOC under my dash and ran the RCA cables along the sides of my truck and tucked them under the trim. It is a totally clean installation with zero indication anything is not factory, that is until I turn the stereo on and you feel the powered sub. Great product and a great price. I highly recommend.
