No Front right output

[barneythedino 10+ year member]

Just installed my aftermarket stereo, i've done in multiple times without problems but can't seem to figure out why I can't get any output from my front right speaker.

Both front speakers were working pre-install.

Tripled checked wiring at the headunit.

Used one of those metra wiring kits.

The speakers up are aftermarket speakers, somebody had once ran them off an amp, but they took the amp out before I bought the car and changed wiring to run off the stock radio.

Front left speaker works fine.

So now, could it be my headunit? I had this headunit installed in my last car and before i took it out it was working fine but it's been sitting around for 6 months not really seeing much of anything so I don't think that could be it.

Next step I figure is to take out the speaker and check the connections on it, but I figure they should be fine if it was working literally 10 minutes before I started installing the new CD player.

Installation is in a 1993 full size blazer. Ready, set, sooolve my problem //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

If u have a portable CD player and a 3.5mm headphone jack to RCA's u can hook that up to ur amp to see if the head unit is the problem. If there's still no signal in the right speaker recheck the wiring. If the wiring is fine grab a DMM to check if there's output from that channel.
