I have a problem with my alpine PDX4.150.
first I explain you my configuration:
I run my system at 3-way mode. the PDX amp accept 4 Inputs from my HU.
channels 1&2 connected to the Mid's and channels 3&4 connected to the tweeters.
the crossover is disabled at the amp and both gains is set to minimum (my HU is PIoneer DEH-P880PRS).
the problem is that I hear distortion from the tweeters. so I tried to examine the problem.
what I did was to mute the tweeters completely at my HU, but when I turn up the volume I heard the low distortion noise sound from the tweeters.
first I thought that the problem maybe at my HU, so I disconnected the RCA of channel 3&4 (TW inputs) from the amp, but the problems did not resolve, and I heard distortion from the tweeters.
it sound to me like there is not completely seperation between the 4 amp channels
I am not sure if I can call these "distortion", it is like some "not cleard" sound.
all of these happend when I turn the volume between mid-high, where I have no distortion.
I hope I explined well.
someone know why I have the problem? how can I fix it?
Thank you very MUCH!
