Ok so I installed 4 prv audio speakers. Added baffles to the rear deck only , for the purpose of keeping the spl away from the rear speakers. I blew the 2 prvs in the rear and decided to go with 4 hertz installed them and tuned them correctly yesterday. Today I drove a measily 30 minutes all 4 windows down and sunroof open, the rear speakers cut out and not the front once again.... turn off hu and got home ohmed everything out and they still said 2 ohms in the front and 2 ohms in the rear.. bridged on a 4 channel rockford 600.4 amp. turned on the hu and the rears worked again... I dont want to blow these....wtf is happening ? Do you guys think that the baffles I added to the rear are making them to hot? And not enough air flow to them? Causing them to cut out? I switched the front wires for the front speakers to the rear input on amp to verify the channels weren't blown and they work as required..Getting irritated as I been dealing with this issue since I installed new tear deck speakers with baffles.. should I remove the baffles? What are your thought on that issue?
