I bought a 7 inch dvd player/GPS touchscreen and was wondering what the best way to install it would be. It is too big to install in the stock deck & I heard i would have to order a new dash bezel for my 2005 chrysler 300 in order for it to fit. Any idea’s?
Grant, you do require a new dash bezel, dash kit or custom installation to make it fit properly. Hope this helps. Good luck.
I just bought a sound system for my 300 and the car don’t have a remote cable. from where can I get power to my remote on my amp?
Emilio, technically you could connect your amplifier turn on wire to the radio switched 12v+ wire. That way your amplifier is on whenever the car is on and off whenever your car is off. Just make sure to run an in-line fuse holder with a 1-amp fuse on the amplifier turn on wire. Hope this helps. Good Luck.
i got an 05 chrysler 300 and need to know what speakers to hook the line out convertor to. some say hook it up to factory sub in back dash, others say use the 6x9s in the back dash. kinda lost here.
Cody, it really depends on what you’re using your line out converter for. If you need the line out converter for an amp that’s powering a subwoofer then use the factory sub wires. If you need the line out converter for an amplifier that’s powering full range speakers then use the 6″ x 9″ speakers in the rear dash. Hope this helps. Good luck.
I want to install a dash flip screen,but it seems like the harness coming from the Chrysler 300 don’t have a accessory wire. i bought a harness plug that plugs directly to car harness it has one. Just want to know how should i hook up the flip screen to harness. Also where do i hook up the the brake ground so that screen comes on.
Max, run a primary wire to the fuse box and use a wire that is only on when your key in the ignition for your radio accessory wire. For ground, just use the car chassis and you should be fine. Hope this helps. Good luck.
Hey i just got an amp and some subs for my chrysler 300. I was wondering what would i hook the audio to for the amp if i want to use the stock deck in the car? I know I can use RCA’s for an aftermarket deck, but i want to just use my stock deck? What do i use to connect my amp?
Matthew, yes you can hook up an amp and subs but it will take a little mobile installation experience. To use your stock radio you will require a line out converter. This device takes two speaker wires and converts them to RCA outputs so you can provide an audio signal to your amp. Here is the Line-Out Converter you need:
Scosche 2-Channel Speaker to RCA Line Out Converter
If you’ve never installed car audio before, we advise you to take your car to an experienced mobile audio installer. Hope this helps. Good luck.
Where would the best place be to run a Power cable (+) from the battery to the amp in the trunk for my subs?. For example is there somewhere down the middle of the car i can run the cable or do i need to run it down the side bye the bottoms of the doors?
Mathew, most installers will run the power cable from the battery, through the firewall, under the carpet (near the door sill) and to your amplifier location for hook up. Just make sure you zip tie the cable down so it does not move. Also, make sure when you run the cable through the firewall that you use a rubber grommet to protect the power cable from rubbing on any bare metal. Hope this helps. Good luck.
ok so i got a amp wire kit but now i dnt know where to connect my amp remote wire too. for my chrysler 300 factory radio still. plz heip me
Lunatic, technically you could connect the amplifier turn on wire to the radio switched 12v+ wire. That way your amplifier is on whenever your 2005 Chrysler 300 is on and off whenever your 2005 Chrysler 300 is off. Just make sure to run an in-line fuse holder with a 1-amp fuse on the amplifier turn on wire. Hope this helps. Good Luck.
i need to locate my factory amplifier on my 2005 crystler 300 if any to install a r.c.a converter before it. can you please help me?
so i got a harness and found out that the accessory wire for the stereo isnt connectin to anything. so where in the fuse box do i run that wire to?
Why do you need to run an in-line 1 amp fuse to your remote for the amplifier?
This is off the subject but what size speakers are in the dash and the doors? I have a 2005 Chrysler 300 (limited)
Issa, the in-line 1 amp fuse is just to safe guard against any shorts. Hope this helps. Good luck with your stereo installation.
I need to replace the knob for my GPS in my 2005 Chrysler 300, can I do it myself based on the wiring inside or does it have to be soldered by a trained technician?
I just bought a beautiful preowned 2005 chrysler 300C, and it won’t load the 6 CDs, it will only load one CD. I have read and repeated all scenarios in the owners manual, but i’m not able to load any additional CD’s. The LED on the dash behind the steering will says disk 1, and then the track #….but no matter what I try, i can’t get the other 5 loaded. What am i doing wrong, thank you so much!
I bought a screen deck for my Chrysler. I hooked up a harness to it but I don’t have any sound coming through my speakers. What’s the problem here, if you don’t mind?
Marcos, first double check ALL your fuses and make sure ALL your fuses are good. You can do this by using an Automotive Fuse Tester and making sure all of your fuses are not blown. If all of your fuses are good, your 2005 Chrysler 300 may have a factory amplifier that needs to be turned on by your after market radio. The car stereo amplifier trigger wire has to be wired up to turn on your factory amplifier to output sound from your speakers. Unfortunately, we do not have this information but maybe someone from the Modified Life community can post that information here. Hope this points you in the right direction. Good luck with your 2005 Chrysler 300 stereo installation.
2005 Chrysler 300 Touring. I just installed a punch 500 a.2 with one lanzar 12″ Sub and it pounds. I don’t have a center sub in my car, that spot is empty so I sliced the speaker wires and connected a wire to the high input on my amp. I have the remote hooked up to a fuse in the fuse panel but I am having one problem. If the car is running and I turn the stereo off I get humming sound or distortion from the sub and if I turn the car off nothing because no power is being supplied to the remote wire at that time. Where can I connect the remote wire to avoid this problem or what else can I do? I have added a switch for now but would like the amp to turn on and off with the stereo or atleast not make the sound from the sub when the car is running but stereo is off.

I have a new stereo that I am about to put in. Is there a factory amplifier in theis model? I just now thought if there was it might be blown and copuld be the problem. I have looked in the back dash and in the trunk next to the fender wells.
Hey. I want to put a new stereo deck in my 05 Chrysler 300 Touring to add Aux and USB input. I went to two different audio shops in town, and they are telling me different things. One shop is telling me I need a $300 harness with a chip in it so I do not lose functionality on some of my cars features, while the other shop is telling me I just need a standard harness. If someone could provide a little insight on this it would be greatly appreciated.
Hello, I want to listen to my iPhone through my car speakers (2005 Chrysler 300 Touring). I don’t have an auxiliary cord input.. just the car lighter deal. What’s my best bet? An email would be appreciated. Sorry that I am not well versed in car audio. Thanks!

can i use the rear speaker of my 05 chrysler 300 for a RCA Line Out Converter to run a monoblock amp? ive been told the rear speakers are crossed over through the stock amp and i need to use the front speakers for a full range input. anyone? thanks.
I have a 2005 Chrysler 300C with a boston sound system that was stock from the factory. The boston system doesn’t have an aux input, therefore I cannot use my Ipod to enjoy music. I only have a 6 cd changer, but who the hell has CD’s anymore? HAHA! Anyways I got a buddy that had an aux input put through the back of his system that ran to the glove box, and he was able to plug his Ipod to that. Is there something like that available for my car? Thanks, James.

Hey I have couple questions. I have a 2005 chrysler 300c and I have 2 amplifiers one is class D monoblok for the subs. The other one is 2000 watts for 4 speakers 6×9 and I want to use the factory car stereo because has gps but the question is I need to use Line out converter for the monoblock amplifier? Or the both amps?
Claudio, you can install one line out converter and split the audio signal to feed both of your amplifiers. Here are the components you will need:
(1) Scosche 2-Channel Speaker to RCA Line Out Converter
(2) RCA 2 Female to 1 Male Cable Splitters
(2) RCA Cables
When splicing in the RCA Line Out Converter, tap your factory rear speaker wires to get a full range audio source. We suggest you invest in some solid wire taps that wont come loose. These wire tap connectors will allow you to tap into wires without cutting and installs in seconds by hand with no crimping or tools required. If you install a line out converter, your rear speakers will still work properly. If you’ve never installed car audio before, we advise you to take your car to an experienced mobile audio installer. Hope this helps. Good luck with your 2005 Chrysler 300C amplifier installation.
I have a 2005 Chrysler 300 Touring Edition and purchased the wiring harness on amazon for my car. The factory radio has two connectors on it and the one I received has one. Where does the small connector go to and after hooking up the power wires to the wire harness my new radio won’t come on. Any help would be nice.
have a 2005 chrysler 300 radio and only the left side speakers works. any suggestions?
Kevin, double check ALL your fuses using an Automotive Fuse Tester because certain vehicles may have a wire tied into another circuit not labeled as car radio. You may have additional fuse boxes by the driver side of the dash, passenger side of the dash, driver kick panel, passenger kick panel, under the steering column or under the hood. If all of your fuses are good, your 2005 Chrysler 300 factory amplifier (if equipped) may be faulty. We suggest you take your car to an experienced audio installer and have them troubleshoot your problem. Hope this helps. Good luck with your 2005 Chrysler 300 radio troubleshooting.
