i bought a 07 ss and the stock sub in the back doesn't work idk if i need an amp or what does anyone have any idea y it doesn't work?

 

ohm it out with a meter , if no reading it is blown. does it smell like burnt rubber in the trunk?

 

naw it doesn't smell burnt or anything, shouldnt it have an amp to work?

 

yeah if its factory it has an amp to run it!, i bought just the sub enclosure and sub , running it off my own amp!

 

Check to make sure the plug on the top is in correct.
If not maybe the leads inside are off but chances are its blown.

To replace it find a shallow mount subwoofer that runs dual 2ohm voice coils
I didn't look that hard but heres an example (I am in no way shape or form saying to get this peticular sub, just giving an example)

your stock amp should still be in the car, it isnt in the trunk, it's near or behind the headunit I believe but I may be wrong.

 

If you didn't have the stock Pioneer amp, your other speakers wouldn't work either (The front compoents, tweeters, and rear 6x9's). The OEM amp in GM vehicles is usually under the dash somewhere on the passenger side.

It is likely that either the sub itself is blown, there is something wrong with the wiring from the amp to the sub (or possibly the connector), or the amp itself has lost the subwoofer channel.

Also check the Eq just to make sure you don't have the subs turned off.

 

how big is the stock amp?

 

Not that big. Pretty sure it's on the driver's side.

 

wud it be under the seat?

 

Unlikely... there isn't room for it under there with the rear HVAC vents.

As I said, in GM vehicles it's usually behind the dash somewhere... likely the Passenger side (If someone here is a GM Tech or has access to the Helm Manual/Alldata, please clarify this)... You'd probably have to tear the dash apart to find it. Again, its much easier to test the sub first to make sure it isn't blown. If the sub is blown, it isn't difficult to unbolt it and replace it.

If you have the Pioneer 7 speaker system (You will have tweeters on the triangular piece at the top of the door... its behind where the mirror mounts) and your non-sub speakers work, then you do have the amp.

 

how would i test the sub?

 

As ctc said above, you would need to hook it up to a meter to see if it reads 0 Ohms. If it reads 0 ohms, its blown. I'd say take it to a car audio shop and have them look at it. There should be a million of them in LV.

 

o alright thx, so theres no way to get to the amp if it isnt by taking something apart? and what if the sub isnt blown?

 

might be an amp or wiring issue!

 

kool thx for the help guys

 

the amp is tucked under the dash on the drivers side about 6 inches from the steering column. its a grey box about the size of a vcr tape attached to a black grill looking panel

 

I got subs put in, and now the stock one doesnt work anymore.
I dont know if it would sound bad with it working with the other two tho.
