thanks from the reply. i have a newish headunit (sony) and the speakers are 4inch pioneers. they are actually ok for no bass, just sound a bit wank when its cranked up.. but are loud enough for me. haha, still may get some 6x9s see how it goes. to be honest its not to much trouble or money, just got other stuff to buy first. least its got rid of the cracking, popping sound, coming from the toyota ones.
