Question about Car Audio & Video
Each time when a new song start to plays, a loud noise seems to be appeared from the sub woofer and also speakers. Btw my I'm using pre amp with usb .What's is my problem actually?
The problem is that you dont have proper earthing on the amp so that is why you will get a engine idling noise. you may need to put in a device called a supresser which will connect to the amp, or try using a 8 to 10mm earth cable from amp to the booth body for earthing. also make sure that you are not taking the earth from your car battery cause that will cause the noise aswell. hope this helps you.

sounds like you need another amp, if the amp has a speaker already connected to each channel, you have no open channel to connect a sub-woofer.
Some years ago I seen an amplifier that was designed to use 3 speakers on 2 channels. what they did was had a speaker on each channel and then they bridged the 3rd speaker across it. That amplifier was designed for this configuration, unless you have an amplifier like that you should not try it. It may result in smoke from the amp.

If the amp produces no boom with no signal input cables connected, I'd suggest using an LOC.
Let me know if you have any other questions.

At the Onkyo, check to make sure you have run the speaker setup starting on Page 40. If that doesn't work...
Disconnect the subwoofer pre-out at the Onkyo and move it to the VCR Out, tune an FM station and be ready for some real loud subwoofer output if your sub has no volume control of its own. If you can hear the sub, it works and it's back to the Onkyo. If not, the unnamed sub
