I recently received a MTX 421D and 2 MTX 4500 10" Subwoofers as a gift. I installed the amplifier and I installed the subwoofers into an MTX box that I had. Basically I replaced the amplifier and the subwoofers that were already in my car with the new ones. The old amplifier was a Coustic Power Logic Amp 260 and the speakers were 10" MTX Road Thunder Two's. The box also had 2 tweeters in it both were Motorola 502's. The box was purchased as a whole unit when it was originally purchased. Anyhow when I hooked everything up the way it was orginially the tweeters won't work, the new subwoofers and amp work fine but the tweeters don't. The tweeters were jumped off the subwoofer originally inside the box and that is how I hooked them back up but they don't work. Any ideas as to why? Sorry if the answer should be obvious but I have no clue as to why.
