Rear speakers acting goofy

[kalikidd6600]

How we all doing out there? I have a very goofy thing happin at can't figure it out. I got a 2000 GT 4dr with the factory Delco Deck CD EQ ect. I replaced the speakers all around but the rear speakers only work if it has be in the SUN. If I park it in the garadge no sound at all. The org. speakers did the same and thats why the up grade to Polk. I ran all new wires and i am baffeled?

short in a wire or loose wire connection? before i got my stock rear replaced they would only work after hitting a decent size bump. Audio place i get all my stuff from said it was blown and hitting the bump would position/jolt the voice coil in a certain way causing it to work again. Not saying yours are blown since you just got them but i would check the wiring real carefully.
