so i recently installed two infinity Reference 860w's, a lanzar DCT425 and a billz audio 2.2 farad capacitor in my jeep cherokee. all seemed well at first but then i started noticing a static noise coming from my car speakers both with the car off and on. the two front door speakers and the two rear door speakers. so i went back through the wiring and made sure all the grounds were clean and had a good connection. everytime i did that it seemed to help for like a day the noise would stop. but id park my car at night and in the morning when id start my car back up the static noise was back. i played with the amp a little and when id turn down the master volume on the amp the static would go away. i only seemed to hear it when the bass would hit. i read online for a few simple fixes and tried them. i made sure my rca's werent running along side my power, didnt change anything. i tried sticking a speaker wire on the outer ring of one of the rca's and grounding it to the deck, helped a tiny bit but it was still there. i tried grounding my deck straight to my chassis, didnt do anything. im really stuck hear. does anyone have any advise? thanks!
