rear 6x9 bass noise

rear 6x9 bass noise

theres a noise coming from my 6x9s when theres bass that hits hard it sounds like hte cone is kind of hitting something, do u think its possible that when i was putting my rear deck back together after installing them that the insullation stuff thats in between the metal part of hte deck and the plastic part that i put it over the speakers instead of lining up where the wholes are for the speakers?

is it a vibration noise or a poppin noise.
If its vibration, you might want turn up ur music and go back there and see what is vibrating. I never really took a close look at the rear pannel so I dont know what can cause the problem.

If its poppin noise when you hit a strong bass note than your speaker are pushed too far and cant handle it.

poppin noise, wudu i do about hte poppin noise do i need an amp or just keep the bass level a little lower?

That poppin noise is your speaker clippin. you said you dont have an amp, that is the problem. Im guessing your speakers is around 100wRMS or more. The problem is your HU is not sending enough power to it. Any Hu you buy in the market will give you about 13wRMS or so even though they claim 25wRMS. (except for that panasonic that is 60wRMS which you need an amp kit). You are not sending enuogh clean power to it and your speakers are distroting.

Yes am amp will help, you can turn it up higher and the music will be cleaner.

For you I recommend a 4 channel amp not a 2 channel amp bridged. The reason why is your rear speakers are stronger than your front so if you bridge it, and turn it up, the front speakers will be maxxed out while the rear speakers will be asking for more power. And it is not good to amp the rear only and not the front because that will mess up your whole sound staging.
Get a good 4 channel amp, trust me will sound a lot better. There is a big difference between ampped and no ampped system like day and night.

I have this popping sound problem. It seems like a cone paper is vibrating. It only occurs when I play hard bass songs. Otherwise, the bass it produces is quite good.

the pioneer 6x9s are 40 rms

Re: rear 6x9 bass noise

Does the problem go away if you fold the rear seats down or if you disable the sub?

ill try that but why would that do anything? air pressure in the trunk?

Exactly. When the sub hits, it pushes the cone of the 6 by 9 - since they are low power drivers, they will have a limited range of travel and they may be getting pushed enough to bottom out.

whats the solution to this? makeing a spacer for my seats???

The first thing you have to do is make sure that that is the problem.

that is the problem i drove a while with the seat down and it sounded fine.

What you want to do is accoustically isolate the rear speakers from the sub. Build boxes that fit underneath the rear deck and seal off the rear speakers so the subs don't push them. This will affect the acoustic properties of the rear drivers (the "Q" will increase), so they may sound a little different, but at least they won't bottom out.

The other option is to replace the rear drivers with something a little more substantial.

can i just make a spacer between my back seats?

You can do whatever you want.

i decided im going to use passive crossovers to eliminate hte bass from the speakers becasue thats when it is happening. i dont need the bass from these speakers anyways because i have 2 12" subs.

That might work - it's not tha cause of all of the problem, but some of it. If you use a passive crossover, it's cheapest and best for the amp to put it between the head unit and the amp, not between the amp and the crossover. That way you'll only need a very small capacitor.
