whine noise from subs

86ranger4x4owner · Oct 14, 2011

Ok i have two 12 duals and i get a whining noise from them and it gets louder as rpms increase.i have all my amp wiring beside each other.So can it be cause of all the wires are together i heard it could be or what else could i try?I also found out on the amp if i cange the x over or crossover to lpf it clears up all the way but when i put in on full it whines and whines more when i turn on the lights or rev the rpms up.the amp is spx pro audio anyone know where i can get an online mauel at and the truck is a 1988 ranger super cab with the 2.9l.thanks for the help

Sounds like its interference from your wiring. Try moving your signal wires from your receiver away from the power and ground. About a foot and a half should do.

what kind of RCA wires are you using?

86ranger4x4owner · Oct 15, 2011

Idk the wires were in there when i bought the truck i think scoshse though but i boght a scoshe amp hook up kit and didnt use the new rcas just the olds ones but it only whines whdn u change the x over but when u put in on lpf where the subs just hit it works fine but on full where it hits and plays music it whines

what you should do is run the new rca's down the other side of the cab as the power wire (for example, if your power wire runs down the drivers side, put the new rca's on the passengers side) this fixed it for me, and mine did the same thing, it would.scream like a banshee, i just got the 11$ scoshe shielded rca's at walmart and it works fine now

also, do you have a good ground on your amp? thick enough cable? scrape the paint back from where you hooked it to they body/frame?

new rca's ran opposite side of the power wires usually fix this. check all your grounds tho. battery, radio, amp, hood ground strap... yeah, it makes my amp whine when that hood strap broke... idk, lol

or get quality cables. i have a 20 foot insulated monster cable ran right next to my 4ga and 8ga power wires with no interference at all. but the powers are tsunami wires too... so idk. and one set of my rca's arnt even insulated at all, infact there from a dvd player.....

i had dvd player cables in mine one time... hearing and feeling my turn signals bothered me. haha

It's your ground wire.. If u wire your amp wire and your cd deck wire need to be the same ground and that won't happen

86ranger4x4owner · Oct 17, 2011

Okay but I don't understand why it only happens on two settings and not the other one and it's not really loud but u can hear the whine.

86ranger4x4owner · Oct 17, 2011

ok i changed the speakers wires going to the subs from the amp,changed the ground location and moved the remote wire and rca cables away from the power wire still no luck.and it doesnt whine when the truck is off just when it runs if you listen really closley to the subs u can hear the truck running so would a power wire filter stop this?

check your rcas in the back of your deck... maybe there loose.

nope there not loose either.If you listen to the speakers closely on full you can hear the engine running when its on lpf it is clear but on lpf it only hits and on full it hits and plays music.And other ideas?could it be a bad amp?Can you get a filter to put on the power wire to clear the noise up?

mind putting pictures up of how everythings hooked up to the amp? that might help us source out some problems. try moving your amp to a different spot.

I dont know how to add pictures on here but i can tell you how i got it hooked up.Ok i got my power wire on the positive terminal bolt and ran through the drivers side firewall and down the kickpanel and under the carpet to behind the drivers seat.the rcas are ran from.the radio down the dirvers side with the power wire and so is the remote wire.the ground is on a screw near the drivers side and the amp is under the drivers side seat.
