 Subject: Sub "pops" when radio is turned on
IP: Logged
Message:
I installed a pair of 8" subs in the tool tray under the left rear passenger seat in my 1997 Dakota Extended Cab. I also have a 400 watt amplifier underneath the driver's seat running the 8's. This setup won't win any competitions, but it does round off the sound nicely.
Here's my question... the sub is now "popping" when I turn the radio on and off. It seems to only have started since I have re-arranged the wires to make things look neater. I have since put the wires back to where they were and it is still "popping". Do you think that I am just getting noise through a wire somehow or does it sound like I messed up the amplifier? This thing's got me stumped... Thanx

Well sometimes the stock cd player will make the subs do that,but if you upgraded its more than likly a bad ground somewhere so check the wires to make sure where there grounded that theres no paint or anything there breaking a good ground.If that doesnt help and they still do that you could look into a ground loop isolater.

are you using the remote wire or a key-on wire to power up the amp? If you use a key-on wire (which means that the amp will be on whenever the car is running) then you might get a pop noise when you turn the radio on and off.
Using the remote wire (Which turns the amp on and off with the radio) avoids this since the amp usually has a small turn-on delay.

Thanks Guys,
I have an aftermarket Pioneer MP3 deck. The amp turn-on wire is connected directly to the deck so it turns on and off with the radio. I wonder if the radio has some sort of delay setting??? will have to check the manual.
Since the remote turn-one wire is a cause of noise sometimes, maybe I damaged the insulation on one of the wires when I was moving stuff around... I'll check to make sure those wires and connections look okay.
Also, what is a ground loop isolator and how does that work?

It just stops some of the noises like road noise from a bad set of rca's or from a bad ground,but yes like JIM said...i almost forgot about that i've had that problem too.Watch your little light on the amp when your turning the radio on and off it should come on a split second after the decks powered on if its coming on befor the deck the subs will pop...or my problem is because of the eclipses 8 volt preouts not working with the amp so to make mine not pop i have to turn the deck off before killing the dakota

Do you have your amp wire running down the same side as your signal wires? This might be the problem.

just check your RCA's first. go buy a good set of RCAs if you hear any funny noises from your actual subs. redo your ground, make sure you sand away all paint, tightly secure it down to a seat bolt or something with a good ground (dont just drill a hole) use good wiring for the power and ground and upgrade your remote wire to a bigger gauge. this sends the signal a bit faster, will def. make your system work and sound better and will probably fix the noise. probably about 30$ worth of wiring and an hours worth of actually redoing the wiring right. you wont be sorry.

If you have poping or road noise check your ground wire. If it is good and tight you will need to find a better spot for it because its not providing a good enough ground. I have also had this problem and I talked to some pro's and thats what they told me.

I checked the ground and it's pretty solid. There's a 2000 watt power inverter on the same ground as the amp. The inverter will get the 4awg power wires hot, but the connection to the frame stays nice and cool.
Sounds like it may be narrowed down to the RCA's. They're routed away from the power wire, but are the cheap ones that came in the Scoche wiring kit from Wal-mart. After listening real close, the sub is not only picking up noise form the turn-on wire, it's getting some engine noise and noise when lights are turned on and off.
I gotta stop buying that cheap stuff from China :) Thanks everybody for the input!

Yea, its probably the rca's and i would recomend IXOS wires and there not cheap but are good.

i have a slight suggestion to your problem. It sounds like to me you may have to many watts running to yours subs cause you said you have a 2000 watt powwer inverter and a 400 watt amp and how many watts are the subs rated for.

so try un hooking the power inverter from the system and hook it up without is and see if that doesn't solve your problem cause it sounds like to me it may be trying to blow the subs.

The inverter has absolutely nothing to do with the subs. Inverters are those devices you use to get 115 VAC from your vehicle's ~12 VDC supply.

A ground loop isolator is just a bandaid. ground your deck to the same place your inverter/amp is grounded. make sure the ground cable from your amp is not longer than 18 inches, which is I believe the leingth of the ground wire which comes with the wal mart kit. and make sure your grounded to a part of the immediate frame, or something which is directly welded to it, not just some random metal pannel. your inverter is puting way too much interferance into your electrical system and especially if you still have a ground loop it's gonna go right in to your sound system.
