it is convenient and easy to install, rather than locating and splicing a million wires for all speakers, but it introduces some noise to the signal even when the head unit is off and not playing any music
I tried many things and was able to isolate the problem to be coming from this device
the noise is not always noticeable from the mids due to road noise covering it, but the noise from the tweeters can still be heard clearly
and now that I am planning to sound deaden and insulate my whole car, I will be hearing the noise much more clearly
I expected this to be a premium product, since I paid such a premium price for it, but unfortunately it wasn't
