Putting in a alpine deck into my cirrus

The deck might be damaged. In order to accommodate that kind of layout, there should be a cross over, and a separate 2 channel amplifier for the subs. Without that it's easy to fry the deck!

go to alpine site and download the installation manual for your model

Check your speakers and speaker wires to make sure you have no shorts or grounds. Not knowing what vehicle you are putting the amp in, there is also a possibility that there may be a stock amp in the vehicle. If this is the case, you may have to rewire the speakers and bypass the stock amp.

You need to:

Wire the low level output from the new 'deck' into the stock amp input.

Or replace the stock amp with an aftermarket amp.

I would put things back to stock and see if they now work. If they dont you may of shorted out a solder joint and ruined the cluster which would have to be replaced as a whole. If after you get it bact to stock and everything works I would be hooking up to a different power source. Also its always a good Idea to run an extra ground wire from engine to body when you add a more steroo system or accessories. This prevents electrolisis in the radiator which could eat thru the heater core or radiator.

My homie had the same problem with his escalade they adapted an rca line adapter from the factory wiring to geta signal to his amplifier and it just wasnt hitting like it should so we installed a new deck and plugged the rca cords right into it and boomboom pow it was hittin like a champ-we figured that the stock premium system that was incoprporated into the truck had some sort of an onboard amp that was filtering the bass from the door speakers and which was limiting the bass output to the rca adapter and thus on down the line to the amplifier- so maybe ya might want to look into getting an aftermarket deck and see if that helps your cause-good luck

What you have been told is correct, these proprietary systems are great for the manufacturer, but when they start to have issues (and they will) they leave you 2 options: pay through the nose to stay original or replace the amps with new ones....the upside of this is aftermarket amps are soooo mugh better than stock that it is lauhgable.

You will only need to connect the door speakers to the MRA-F350. In short, the connections will be as follows:

Deck---->MRA-F350 amp---->Door speakers
...................................\---->Sub amp---->Sub(s)

Just make sure you use the optical digital output of the deck to connect to the optical digital input of the MRA-F350 amp, not the RCA preamp connections.

What kind of car did you install this in? Did it have a factory radio in it? If I had to take a guess I would think that there is a factory amp that you may have hooked the blue wire from the alpine deck to. If this is the case when you switch to CD the alpine deck turns off the power to the power antenna lead(blue wire) and thus your factory amp. If this is the case hook the factory amp turn on to the blue and white wire and you should be good to go. The same goes if your have an aftermarket amp driving your speakers.
