    so to further curiousity, or maybe just to pin the tail on the donkey, i removed all speaker wires, and the amp is a go(light is green) when i hook the sub up to the rear i get a pop sound then deadening of the amp(red light)
    however i did try placing the rear output of the stereo to the front in the amp, and placed the sub on the front outputs, and ti seamed to work.........(crappy since its highpass filter not rear speakers) is this conclusive that the amp rear output might be fried?

If the protection Light is on thats an indication thats to tell you that theres something wrong with the amp. Or the speaker. Try to first with the amp off!! Disconnect all the speakers to the amp. Turn on the amp. Is the light still on?? If it is then that tells ya theres a short in the outputs or the driver section of the amp circuit and needs to be serviced. If the light goes off then check the speakers for shorts and the speaker wires for a pinched wire running to the speakers from the amp. I must have found hundrens of pinches during my hay days of troubleshooting vehicle systems. If your not a tech Im sorry theres not much I can assit you with the repairing of the amp as there are no user serviceable parts inside and you need special equipment to fix them. your gonna need to seek a pro to assist in the repair of the amp. Good Luck

How to hookup a bose 321 to a toshiba 58l7300 tv

The Bose system does not appear to have HDMI output. The best-quality method would be to use Component (RGB) cables with analog audio. One RCA pair will be for audio and these are often RED & WHITE connectors, but don't have to be. Any RCA pair will work. Connect these to the Bose RED/WHITE jacks found in the "TV" labeling. Connect the other ends to the Toshiba's RED/WHITE jacks on the bottom row, first two jacks.

Now you need a Component cable. This has three RCA connectors at each end and are traditionally RED, GREEN, and BLUE. Again, colors do not matter as long as you connect the ends so they match. Under the "Component" labeling on the Bose, you will find the three colored jacks. Connect these to the Toshiba's same-colored jacks which are next to the RED/WHITE ones you used previously. These three connectors carry the video signals. They will transfer Hi-Def 1080i signals, not 1080p, but you wouldn't be able to tell the difference.

Switch the input on your TV to "Component".

The three picture cords (red/blue/green) often are a little larger around than the sound cords (red/white). If they are they same size, they are often grouped separate by picture and sound. Double check to verify if you have the "red" cords correct. Good luck.

I want to switch the power on my car cd player away from the starter, so that i have to turn it on and off myself, rather than when i turn the key. how??

Surely you mean that your cd player is connected to the accessory power and not the starter. If you want your cd player to receive constant power then locate the accessory power wire of the cd player(the one that receives power when the key is on) and connect it to a FUSED constant power source(battery). Usually, if it's a three wire hookup it will be yellow, red and black. Yellow (constant power), red (switched power) and black is ground. If this is the hook up then the red needs constant power. If it's a two wire hook up, red (switched) and black(ground), then the red needs constant power.

I have two amps one for my speakers and the other for my subs it was working fine but recently one of them turned off. I thought was a short circuit and bought a new one but still doesn't work. Its looped...

When running multiple amps you need a relay most of the time for the remote wire off the radio this is because the radio was built to power one not multiples. one 12 volt relay may help .check local car audio store. also when hooking up relay it has to have a 12 volt power wire connected to it usually the center pin on the relay is your connection for the power wire the you connect your remote wire from the radio to the relay then connect each amp independently to the relay. Hope this helps write back if not . and if so leave feedback

New cd player made in china

The yellow wire does not get used unless you have a power antenna to hook it to. The red wire is suppose to be hooked to the wire that was used as power for the stock stereo, so it turns on and off with the key. If you have it hooked to constant power, it has power coming to it even when it's turned off. That and the fact that you may need a better ground is most likely the reason you're getting the moise even when turned off. You may also want to check your speaker connections.

No power to subs

I think the blue wire is a standby "on" to be hooked to separate or system switch. Without knowing how you have system wired, I can' offer much. A bit of caution; having a thousand watt amp hooked to 6x9 dooms their fate

Amp is on but nothing coming out of Sub

If one amp works inthe same place same wiring same hookup, and the other one dosent, It got to be a bad amp or the way its being hooked up. Make sure the standby is hooked up properly. Get the wiring diagram for instalation for both amps and look at them side by side. If the dead amp is supose to work then Im sure by comparing hookup your gonna say "AAAWWWWW I See Now!!" Good Luck
