im trying to hook up my alpine headunit...but its not working...the power goes on and everything....but no sound comes out of the speakers....is their something im over looking?....also my sub amp which gets its signal from the factory amp...turns on whenever the radio tuner is on..but then turns off when i switch to cd...

any suggestions?...im pretty sure the wires from the headuniot to the metra harness match..thanx

 

I would check the speaker wires for sure. Should be like green, green/black, white, white/black, purple, purple/black, grey and grey/black. If you have power, thats about the only thing to look at.

As for the sub amp, I think you hooked up the blue/white wire from your Alpine and it should be blue. The blue/white is for power antenae and will only work with the radio on.

Double check your wires and let us know.

 

One other thing I just remembered. If you are using the Alpine's internal amp, you need to check in the system settings for the internal power. I forget what it is called exactly but, it is a feature that allows shutting down the internal amp if you have external amps. It reduces heat within the head unit. Make sure it is set to on. It might be like "IC POWER" or something like that.

 

wow..thanx..your a genius..that worked....

ok...now my question is how do i get the sub amp to turn off for all of the sources...not just radio?

 

Not sure what you mean. Do you mean sometimes, you do not want the sub on with the stereo on or just how does the sub amp turn off?

 

bassicaly i want to know how to get my aftermarket sub amp to turn on and wrok with my headunit....and also my subs...what cables do i have to buy...or what do i need to hook up?

 

Once you have power hooked up to your sub amp, you need to hook the remote wire up to the blue wire on the Alpine. Not the blue/white. That will provide the remote signal whenever the head unit is on. When the head unit is off, the amp should be off too. The sub just needs speaker wire from the amp to the sub. I am not sure how much of this you are asking. Be a little more specific on what you have done and we can help alot better.

 

bascially to reiterate what you have done, and what AcuraX2 has said, you hooked the antenna wire up to the factory remote turn on. in the alpine the ant. wire loses power any time you put in a cd so the factory amp obviously would in turn lose power. just switch the wire from the blue to the wlue with white (i might have that backwards, so which ever you don't have wired now, wire it up in place of the one you have wired.)

 

got it...thanx guys

 

that is a nice list of equipment. do you have any pics of the install?

 

yeah...i'll post pcis when im done..should be soon...the screen and headunit i got from shawhite....so you've probably seen it in...i'll post pics of the rest of it...altho it might be kinds messy...ive decided to only flush mount my navi unit...im to lazy to flush in the cd changer with the wall in my trunk...maybe later...

bassically tho....all this was jsut so i could get navi
