Axxess AX-ALOC648 4-Channel Adjustable Line Output Converter 80-Watt

I have this in my trailer in my trailer for my radios amp. Works perfectly and seems to be solid sound and build quality.

This product was used on conjunction with a Crutchfield aftermarket radio install in my son's Grand Am.Because of the On-Star GM wiring, a special Metra converter was needed to retain the warning chimes feature on this car.This special Metra converter came with the Crutchfield radio package. However this Adjustable Line Level Converter wasalso needed because the output from the Crutchfield supplied GM On-Star converter output was at too high a voltage levelfor the existing factory power amp which came with the car.This item was easy to install and the level adjustments necessary after the install were easy to perform.I recommend this product to anyone facing a similar problem.

Easy to use and install, ABSOLUTELY terrible knobs.The knobs on these are like a chick who has lost around 300 pounds, and then regained it. They are flimsy and fragile, with no feel in them.Honestly Metra, what the hell?Also, don't ground it in modern cars, no need.

Works very well

This line-level 'tap' worked really well. I used it to pull main surround audio from the speaker-outs of an hdmi AVR to feed the inputs of a second non-hdmi surround amp. Audio quality was good, no noticeable degradation.One thing, the instructions and explanation for adjustment and explanation of which RCA outs matched which line in wires was poor. Only way to get channels right was trial and error.

Everything that was advertised was inside the box excellent quality product. I haven't had a chance to install my amp yet however this will do the job that I need done. Price was also unbeatable with the Two day shipping it beat my expectations. I will update once my amp is instaled

Worked perfect. A little touchy to adjust.

One of the 4 channels does not work.

Works as described
