thanks to all the suggestions on my last post about my focal cv1's well i went out an bought an amp: infinity reference 7540a. (the refurbished one) 111RMS X 4. (I am hoping to buy sub soon to connect to the other two channels) now the speakers blast. I had to unhook the factory tweeters because they were too loud and gave me a headache. (any suggestions on how to keep them in the system?) now my only problem is getting the whole car to stop rattling! I feel that i am loosing sound quality as a result. What works?
