POP when turning car off

[Partagas 10+ year member]

I looked through the threads but can't seem to find what I am looking for so I hope someone can help me with this.

I just installed a soundstream 1700 watt amp with 0 gage wire running to a block and then 4 gage going to a 5 farad cap then back to the amp.

When I turn off the stereo (or car) my subs have the loud popping sound like a big current or something goes through them. Is this caused by the ground? and if so then do I need to change my ground block to another location.

Thanks

from reading about caps in the other threads I will pull mine out to see if it makes a difference but I don't think that it will stop the pop when turning the stereo off

more often than not its a bad amp ground. where is your ground?

i had a pop everytime i turned my car stereo on. it was because i had my comp amp hooked to the fuse box instead of the remote wire on the stereo.

try re-grounding the amp, make sure that it is clean bare metal.

I have the amp grounded about 12 inches away on a block the only thing I can think of is that it is right next to the transmission and in the area of the parking break. Also because it is 0/1 gage wire I had to getto rig it by using a bunch of ring connectors. I really don't hink that makes any difference but I'll have to change it later. I'll put a pic of it up in a few to see if anyone can see something wrong

I left the cap out

them are kinda BIG. Well anyway as you can see the amp is not very far away and it goes right to the ground block. I guess I can ground each individually to a seat post hole, but I have an amp under both front two seats and a cap also.

My remote turn on comes from the stereo power att/remote and it is split between both amps I do have it next to the ground and I can move it that should be easy.

nice amp......



take a dmm and check the resistance from the amp to the chasis. and the chasis to bat-.

Soundstream makes good amps i can't compalin there...unless mine is bad and thats why its popping //content.invisioncic.com/y282845/emoticons/furious.gif.fc81ca146dbff91fede3ed290dbc4f4c.gif

My Big 3 upgrade that I did a while ago...all 0/1 gage wire...still popping after that

I'll go ohm the thing out now...

00.3 ohms thats **** good for a ground

Well its more like a thumping than a popping, like an extra bass beat. just thought I would clear that up.

Do you think that it can be caused by a bad deck? I bought a Alpine CDA-9855 to see if that fixes it
