shooter69 Posted October 4, 2007 Report Share Posted October 4, 2007 Ok, so I installed a buddy's system for him last night. He bought two used MTX 8000's, in a sealed box, and a Hifonics 1206. The truck he just got came with a pionneer head unit, power wire already hooked up, ground already bolted down, remote wire plugged into the head unit, along with the RCA cables already installed, and ran to the back of the truck, to where the previous system of the previous owner had been. Well I got everything hooked up, and we start playing some music. I start powering up the amp and the subs get to moving. I finally get the amp tuned pretty well, but then I turn down the music to ask him if he's happy with the setup but immediatly I notice a steady buzz coming from the subs. In my opinion, I think the RCA cables aren't up to par and are recieving a horrible signal...(they look really old). I talked to another who had the problem and he suggested the speaker wire, but the wire is brand new, 12 gauge...plenty big for the low wattage system. So tell me guys....what could be the problem?

AI James Posted October 4, 2007 Report Share Posted October 4, 2007 touch the ends of the rca's to somethign metal and see if it goes away, if you have a pioneer HU just ground out the RCA's it will go away Link to comment Share on other sites More sharing options...

shooter69 Posted October 4, 2007 Author Report Share Posted October 4, 2007 I told him to get some new rca's, and I'll see if I can't show him a better ground. (1)Fi BTL 15 (1)AQ 2200d 4.33 Cubes~33hz Big Three done XS 1200 in the back Link to comment Share on other sites More sharing options...

Forevrbumpn Posted October 4, 2007 Report Share Posted October 4, 2007 yeah, pioneer head units, dunno why, I had 2 that did the same thing. I tested it by twisting some thing gauge wire around the outside of the RCAs at the deck, and no more noise.... I have a ritual called "terminator". I crouch in the shower in the "naked terminator" pose. With eyes closed I crouch for a minute and visualize either Arnie or the guy from the 2nd movie. I then start to hum the T2 theme. Slowly I rise to a standing position and open my eyes. It helps me get through my day. The only problem is if the shower curtain sticks to my terminator leg. It sorta ruins the fantasy.

E a r t h Posted October 4, 2007 Report Share Posted October 4, 2007 Are the RCAs routed close to the amp power wire? That can induce noise into the system Link to comment Share on other sites More sharing options...
