Installed new deck now right side speakers crack?

-ok so i bought a new pioneer deck and installed it correctly all the correct wires to wires with electrical tape surrounding the wires. but i get this crackling noise out of my right side speakers. ive checked the wiring over and over on the deck and the door speakers and none of them are touching metal. Should i replace the wiring harness to the deck or could it be the deck it self thats causing the speakers to crack? Any suggestions would help me at this point. THANKS!!!scenario A- (fix this even if its not this causing the problem) Its your wiring. using electrical tape alone isnt good enough you either need to soldier first and then use tape, or use crimp caps. the wires aren't getting a good connection and making a crackling noise.



scenario B- The channels on the radio are bad and you need to exchange it.



scenario C- The speakers are blown. Ive blown speakers in a matter of hours before (I'm also running a 600x4 for speakers, but thats off topic). It doesn't matter how recent you put them in, you could have blown them.
You can isolate the problem by using a test speaker. Pull the wires from a door and run them to a test speaker. If it cracks, its your deck. If it doesnt, its your speakers.

And like the other posters said, you should really use crimp connectors or solder the wires in addition to tape.
