Hello,

I drive an 04 acura rsx type s, and resently i have been getting engine whine noise only from two speakers. one is on the left door and the tweeter located on the left in the dash by the windshield. But the weird thing is that it comes and goes. somedays i have the noise some days i dont. i took it to the place were they installed
-pioneer avic z1
-two JL audio 10' subs
-with a JL amp and capacitor.

it and it didnt make noise. then two hours later it starts making the noise.
any idea what can case the problem? by the way am still on stock bose speakers.

 

Take it back to the place that installed it and have them fix it.
