dcromero Posted September 14, 2005 Report Share Posted September 14, 2005 I have a bose system. I replaced the headunit and added a amp and sub. I used the Pac adaptors mentioned on the site including the box to retain the door chimes. Now when I turn on the stereo I could hear the engine through the left front speaker. It's going the drive me nuts I think the problem is that I hooked the amp power wire to the bolt in the red box by the motor instead of the battery. Could that be the problem or is it something else?

fox_forma Posted September 14, 2005 Report Share Posted September 14, 2005 i believe it has to do with something not being grounded correctly somewhere. But where is the question????...... Quote Link to comment Share on other sites More sharing options...
dcromero Posted September 14, 2005 Author Report Share Posted September 14, 2005 I get a constant loud buzzing sound of the engine in the speakers. Why would that happen? that is the question. Is it a ground? power wire? and why would it effect the regular speakers? Quote Link to comment Share on other sites More sharing options...
6.0ss Posted September 14, 2005 Report Share Posted September 14, 2005 You have connected the Pac Audio unit up to your factory head unit, That part intercepts the singnal to the Bose amplifier so you are obtaining noise throught that thing. First try just disconnecting the pac unit and plugging in the bose system the normal way. if it goes away you know it is the pac or the rear amp. How to get rid of it. First. Make sure your Power Wire for the amp and the RCA cables from the pac unit are not run on the same side of the car. This causes noise and might make its way back into the pac unit and into the bose amp. if that does not work. try moving the Grounding point for the pac unit. Move the Grounding point for the amplifier. Having your power wire from the red box is not going to do anything for engine noise. If none of that changes it. try a noise suppressor on the pac unit power wire Quote Link to comment Share on other sites More sharing options...
dcromero Posted September 15, 2005 Author Report Share Posted September 15, 2005 "UPDATE" I moved the RCA cables and that didn't work. all the grounds were ok. I changed the mounting location of the amp power wire to the battery and that didn't work either. I have a kenwood MP3 hu with a Pac adaptor OS-2 bose with cm-1 (chime module). the amp has a AOEM-GM24 or OEM-1. Has anyone else have the same problem and what did you do about it?

6.0ss Posted September 15, 2005 Report Share Posted September 15, 2005 Ohh I missed that it was an aftermarket deck.. Im sorry. Does the Wine Change Pictch with the engine RPM? R the Factory bose speakers being used? R they powered by the aftermarket headunit or the stock bose amp? Is there any wine that comes from the right side speaker? Ill check back in a little bit to see if you have answered. Quote Link to comment Share on other sites More sharing options...
Jonmalibuss Posted September 15, 2005 Report Share Posted September 15, 2005 I have not done anything to my factory sound system and I get a high pitched whine through the speakers once in a while. It also goes up and down with RPM Quote Link to comment Share on other sites More sharing options...
dcromero Posted September 15, 2005 Author Report Share Posted September 15, 2005 the whine does change pitch with the gas pedal and trans shifting but stays at the same volume, It doesn't go up with the volume. yes the factory bose speakers and amp are used. Im just adding another amp and 8" bass tube. the sound only comes from the left door speaker. I did find something about using 1k ohm resistors inline with the negative speaker leads from the hu to the pac module. Quote Link to comment Share on other sites More sharing options...
6.0ss Posted September 15, 2005 Report Share Posted September 15, 2005 The real trouble shooter here is.. if you put the factory deck back in does it still make the sound? If it does then take it to the dealer. If it does not, then you know that the sound is generated from the PAC unit. Trouble shooting from there can be easy. Put a noise suppressor on the power wire going into the PAC 10$ at radio shack. Your PAC unit could also be deffective. Something to look into as well. The Last thought is that the Headunit is picking up some kind of interference, but that is not likely. Quote Link to comment Share on other sites More sharing options...
dcromero Posted September 15, 2005 Author Report Share Posted September 15, 2005 I've been running the kenwood headunit for about 9 months without any problem. All I did was install the amp and sub with the recommended pac module in the center console near the factory amp. I"ll have to double check the connections and mess with it a little more. If I have to I'll get the noise suppressor. I've never had problems with a car stereo install as I do with this truck. or I'll just wire the remote wire and rca cables from the deck inself, the old way.

6.0ss Posted September 16, 2005 Report Share Posted September 16, 2005 That old way you are talking about,, is the correct way to do it. If you can bypass the pac unit and just use the RCA from the deck to the Amp do it. The subs will sound better as well. Cleaner signal.

dcromero Posted September 19, 2005 Author Report Share Posted September 19, 2005 "update" Well I bypassed the pac unit and hooked it straight from the headunit. the noise is gone. sounds real good now. Quote Link to comment Share on other sites More sharing options...
