[QUOTE="ewadz3006, post: 7876257, member: 639150"] I cant get the whine to stop. I've done a few things that made it better but its still there. the equipment- 2004 mercury mountaineer, Kenwood excelon 996, aq2200d on 2 sa 12's. aq 120.4 on factory speakers for now, have incriminator comp set but have been chasing alt whine so I haven't installed them yet. big three done in knu 1/0 ofc. a run of pos and neg to the back, distribution blocks (stinger) to the amps 1/0 on 2200 and 4 gauge to 120.4 Also have an old school mtx electronic crossover mtx rt01 i think (3 way). I have two runs of rca's running back to crossover (front and rear outputs). I had power and rca's ran together, ran rca's down other side of car that helped a little. I grounded the rca's to the deck- that helped a little. ran a 18 gauge ground wire from the hu to the distribution block in the back. also tied all grounds together at hu.- not sure if that helped or not. I think my next step is to run the amp straight off of a ipod or something. I have to find my adapter. if that doesnt work I will try new rca's? idk. my rca's are rockford fosgate twisted pair. I'm not sure if they are shielded. Its not too loud and cant be noticed at med to high volume. but when two or more people are in the car and are talking its super annoying. any more input would be greatly appreciated. [/QUOTE]
