Hi,

My 97 TT Cd player skips over bumps. Is there a way to fix this or do I need to replace it.

Plus I have an amplier hooked through my stock stereo and there is a slight whine noise with the throttle. My stereo installer said its the best he can do due to the stock stereo's sound is being amplified.

Thanks.

Your stereo installer sucks. The whine noise, does it get louder as you accelerate?

If it does it's the ground, it's loose or it's not grounded to the chassis properly.

As for the CD player, it's a factory there's not much you can do. Try removing it and placing some kind of foam underneath it.
As to sorta cushion it a bit. but not too much because you still have to let it breath. If it gets too hot it will F*&^ up.

Hope that helps. Peace.

IF relocating your ground doesn't resove your prob, you will have to take the ground on your head unit, stock amp (if still installed) and the ground on the aftermarket, and groung them to the same point. grind the metal a bit and a nice bolt right into the chassis.

Get a better insatller is step two, don't let some wanna be hero fuck your car!

Lastly you will have to clean the the factory head unit. Try a lense cleaner first, if that doesn't do it just save yourself the trouble and get a aftermarket one. And trust me it is a huge hassle to get the lense cleaned and aligned, in a factory system

Thanks for the input. The whine noise is ever so slight though but does not get louder with acceleration.

Also the installer told me that he had to use the stock amp with my amp in conjunction with the stock head unit. So maybe that is causing the whinning noise? Is there a way to remove the stock amp and work the stock head unit with my own amp?

About skipping I'll try some foam as u said Tito.

Thanks again

Still try relocating your ground, but it sounds like you have noise being induced into your system, most likely the install of the aftermarket amp, with the factory one. What happens here is that the noise floor is lowered significantly b/c of the mix and matching of signal levels and impedance inputs. This is happening b/c the factory amp amplifies factory speaker outputs, not rca lines, where by you are now are amplifying an already amplified signal, by which you lower your noise floor.

That is not true; your installer is feeding you here. To do a nice install job retaining the factory head unit is fairly simple, but a tedious job never the less. Remove your front passenger seat, the factory amp resides there. Now you will have to locate the input side of the speaker wires coming in from the head unit. This is where you will be bypassing the factory amp. Buy an adjustable line level converter, how many of these you will need depends on how many pairs of rcas the aftermarket amp accepts. Two input channels = 1 pair of rcas, left right.

You can bypass this if the aftermarket amp has speaker level inputs, but you will have the highest noise floor if you go the adjustable line level converter route.

Find the input impendence on the amp, and adjust the LLC to match the signals, this way you will get a nicer and cleaner signal to the actual speakers themselves.

Just print this article and give it to your installer or a new one, they will be able to take it form there. Make sure to tape off the factory power wires and to properly fuse your battery line and make sure the factory remote turn on is sufficient for your new amp.
