Hi William, I'm glad to help!

William, before running after another cluster I'd make certain that the fuse was not blown during the stereo installation. Check all fuses first with a test light just to make sure. Hope this helps and have an awesome day William.

I just installed boss bv7340 in my car and it wont turn on i checked the ingition wire and ground to see if i was get 12 volts and i was i dont understand

From what ive seen alot of boss audio equipment are defect. You can try checking the fuses and if not return it and get another. Or another way is connecting it straight too the battery of your car (red and yellow together/positive) (black/ground) if it deos not turn on its your stereo.

I hook up a amp with red and black wire from the car stereo, then the stereo stopped turning on, why?

You probably blew a fuse. The power wires for a stereo can not handle the current an amp needs. An amp has to get it's power directly off the battery. Get an amp kit that has the power wire, ground wire, turn on lead, and fuse w/fuse holder. fuse the power no less than 12" from the battery.

You could get a stereo installation kit for your year, make & model, that comes with a pigtail plug that would plug right into the existing harness plug and prevent you from having to hack up your original wiring harness.

If not....

Car Radio memory Constant 12v+ Wire: Orange
Car Radio Accessory Switched 12v+ Wire: The radio harness does not provide a switched power source. Run a wire to the fusebox for switched power.
Car Radio Ground Wire: Black/White
Car Radio Illumination Wire: Gray
Car Stereo Dimmer Wire: Brown
Car Stereo Antenna Trigger Wire: Pink
Car Stereo Amp Trigger Wire: N/A
Left Front Speaker Positive Wire (+): Tan
Left Front Speaker Negative Wire (-): Gray
Right Front Speaker Positive Wire (+): Light Green
Right Front Speaker Negative Wire (-): Dark Green
Left Rear Speaker Positive Wire (+): Brown
Left Rear Speaker Negative Wire (-): Yellow
Right Rear Speaker Positive Wire (+): Dark Blue
Right Rear Speaker Negative Wire (-): Light Blue

Good luck
