Yes.

A 2008 model probably has The mygig system. You need to find a mygig with the nav integrated- I believe it's the RER. Keep in mind that if it's an earlier stock nav such as the REC it will not interface. In other words make sure you look for the mygig nav unit.

When wired correctly the speaker cone will move outward when it hits. If it is wired backwards, the cone moves inward when it hits. This greatly cuts down on sound volume and quality, "a hell of a lost less than optimal". When the installer says it will still work, I guess, technically he's right.

The installer was correct, and there is nothing wrong with the direction
the speaker moves. The idea around creating sound is to move the air.
Unless you have a poorly made speaker, it should be able to create sound
properly regardless of polarity.

The one thing you MUST be certain of is that all speakers are wired with
the SAME relative polarity.

there are some exceptions, however. In a high end competition system,
sometimes the installer will wire certain speakers (say a pillar mounted mid)
in opposite polarity during the tuning phase in an effort to try and get
the sound stage set up properly.

2 questions i have on a 300 srt8

1 where do you find the Reverse back up wireing ? im doing a camera in rear

2 where do you find the parking sencer wire ?

also color codes would help alot too.

any one know or have done this install on a after market set up


O btw if you want to check the polarity of your speakers (See If there hooke up corectley + to + and -to -) from head unit to speakers.......theres a simple test IF you can get to the speaker wires AFTER amp or NON amped system .

useing a 9 volt battery and touch the pos of battery to pos of speaker wire and neg of battery to neg of speaker wire for a brief sec you will see the speaker suck in or pop out the correct way to have it set up on a system is pop out.

I replaced my head unit, as well as the speakers of course, and now I have an alternator hum at about 3 KHz. I think the head unit contained some circuitry that suppressed alternator hum. Any suggestions on getting rid of the hum?
