so i went out and got a new amp which the salesman swore up and down was waaaay better than what i had and was a great deal for the money. so i end up with an orion covalt 200.4 running my mids. this replaced a 10(?) year old pioneer gmh120. no i have an awefull hiss in my rear fill. the dude at the audio place says "well thats damn near inaudible" bs i say. if its more audible than teh 10 year old amp im preplacing that i paid $30 for from a friend 4 years ago, then its hard "inaudible".it hisses no matter what the gain is set at and it hisses with the rca's pulled out, but it only hisses on the rear speakers. it puts out 50x4 rms @4ohm @12volts not quite sure what its pulling out at 14.4. anyone got any ideas to get rid of the hissing? oh teh fronts are an mb quart component set and the rear is polk ex. would you mind un-wedging your fullsize from between those trees? your blocking the trail.
