Hey guys,

I just bought this car used.

I'm not sure if it came factory, but the head unit is an RNS-E MMI.

• 6 CD changer
• 10 speakers
• factory amp
• NO AUX
• NO BT
• NO IPOD

The only working speakers are the front driver and passenger.

The rear doors do nothing.
And the rear speaker (6" sub?) located under the amp in the wagon, puts out a very distorted crunch on every bass kick.

We're under lockdown so I can't take it to anyone to look at.

Can someone tell me where to start.
Fuses, connections, loose wires etc.
Any resources would be appreciated too.

Also I don't have any head unit keys to pull the deck out safely and without damage so, until I get some I can't get behind the head unit.

​​​​​​​Cheers.
