Speaker cuts out when screwed in, work when not screwed in?!

swap you speakers and see if it follows the speaker or stays with the channel.

Make sure your wire isn't grounding out while screwed in. It could be a screw hitting the terminal,the leads slapping the basket, or even the terminals hitting the mounting hole. or if you would like to test it the easy way,use a multimeter with the continuity setting. Probe one end to ground(from your amp or any GOOD ground) and put the other end to the DISSCONECTED speaker line (the one your having issues with) on the amp with the speaker mounted. If your speaker is grounded it will show continuity on one of the wires. Either the positive or negative, now turn your meter into the OHM setting and probe both pos & neg one at a time. One will show (4ohms or whatever therresistance of your speaker is) and the grounded end will show 0 or .01. Take note of the grounded end ( pos or neg) and check that side of the wire . If your wire is perfectly fine and you cannot find any install error then move onto the speaker. It may have a built in crossover (cap) that could have grounded on the frame. I see it happen on Rockford speakers alot. To test, put your meter on the OHM setting, probe one of your terminals on the speaker(pos or neg) then put the other probe to the basket or magnet and see if it reads anything. If it shows 4 ohms or 0 ohms then your speaker is internally shorted,causing the ground issue when installed.
