Question about Alpine PDX-4.100 Car Audio Amplifier
My front right tweeter crackles every few seconds or so. i thought i had a blown tweeter so i changed it out and the new one does the same thing. i then reversed channels 1 and 2 on the amp and the left front tweeter started crackling. looks like whatever speaker i have hooked up to the 2nd channel crackles. my amp is only 2 weeks old. could i have a channel out already?

Make sure your speaker wiring does not come close to the 12v power cable running for your amplifier. If your amplifier's 12v power cable runs on the drivers side of the vehicle, run your speaker cables on the passengers side and make sure your tweeters have a high pass filter to stop any pickup of engine sound (When you are driving you *WILL* notice it at high RPM. a HPF (High Pass Filter) will also stop those nasty hissing sounds on S's.
