need advice

[YukonJ]

OK so a few months ago I replaced my 4 door speakers. Everything sounded fine up until about 2 weeks ago. Here is what is going on:

I only get sound from the RF, LR and sometimes LF. IF the volume is low there is no sound from the LF but if I turn the volume up it comes back. For a while sound came and went when I hit a bump, but only when the sound was low. I thought it might be the connections but it hasn't been affected by bumps in the last few days.

Could my amp be going bad, the headunit itself be bad? Everything is stock except the 4 door speakers. MY sub is blown and I get a little sound from the far rear pillars.

Oh yeah, it's a 2001 Yukon XL.

Thanks, J

my guess would be head unit.. do u still have ur stock speakers layin around? id try swapping those back in to see if there is any change... what kind of speakers did u upgrade to? also is it the bose system? do u have onstar?

Stock speakers were blown so no I dot have them. I put in kickers. It doesn't say bose anywhere but I do have onstar.

sounds like amp.

I'm assuming its the amp behind the glove box correct?

Anyone have a spare factory amp they aren't using after installing a new system? Want to sell it cheap or donate it to a great cause? (cause i don't have any sound, lol)
