O.k. I just had a man over that wanted me 02' 12" L7. I wired it to two ohm because his rockford fosgate amp put out like 900rms @2 ohm bridged. I take it in the blistering heat and hook it up. Nothing happens, so we unscrew the sub make sure its at 2 ohms which it is. He unbridges his amp and we turn it on, the speaker compresses right when the music starts playing, but doesnt move. Finally i say man i promiss this is your amp because i had both hooked up last week and they have been sitting in my room ever since. I go inside and pick up an L5 and we hook it up and it does the same thing, compress when music starts and when it stops it returns to its original position. I am about to hook them both up in my room because i know it was his amp, but what could cause this to happen?
