How is the bass with the stock sub and an aftermarket amp signal, any better?

Xpresion

its stacks better!, it took me a while to fine tune the stock stub as it produces nice bass and can be overpowered very easily and starts to bottom out. but it gives very nice deep base when tuned properly. better then any boot setup. i even tried putting a sub in the boot and facing it though the arm rest at the back seat (i made an opening there) and the bass still sounded horrid as compared to the stock sub.

outside the car with the stock sub i cannot hear a single rattle, yet inside the car it sounded so nice.

With another sub in the boot, outside the car everything rattles, and inside the car it doesn't sound that great.

Hi,

Bad news. Radio arrived. Was missing transport screws and radio is completely dead.
Will raise dispute through AliExpress tomorrow and keep you posted.
Not 100% sure if it is the harness or the radio itself. but suspect its the radio as the transport screws were missing.

So you need an aftermarket amp to power this head unit? You cant just use the stock amp with the aftermarket head unit? I thought these were more just plug and play solutions.

NubyIz

Quick update, raised a dispute with AliExpress with video and photo evidence.
Will keep you posted on how the seller handles the dispute.

Sneers please read the first post entirely. Answers to your question lye there.

Xpresion

wow that's unfortunate NubyIz

you can bench test the radio with 12v supply with at least 2 Amps.

Connect the positive to the yellow cable and negative to the black, you will also have a red cable, this needs to be connected to the positive as well. (this red cable also runs to the CANBUS box. so make sure that the box is also getting that 12v positive . this should cause the unit to power up like it would in the car. if not then the unit is busted.

try this with the long cable and from memory the unit comes with other plugs for cars without optical fiber. so you can try it on that short cable as well. I hope this makes sense?

Hi,

Thank you for your assistance.
Raised a dispute with AliExpress and want to wait what they tell me or ask me to do to (if anything).

Hello,
Thank you for collecting all this valuable informations.

Do you think this cable can be used instead of the 2 you specify:
http://www.aliexpress.com/store/prod...977911542.html

I'm scared to disassemble all my SLK to pass these cables.

Xpresion

are you sure your SLK has amp etc? I thought the SLK did not come out with external amplifier? Also the GPS cable for the SLK is located behind the original unit. so you don't need a 6m cable. (this is going by the fact that i don't believe the SLK had an optical fiber amplifier setup).

I found another Alpine amp with more power and great reviews. It consistently tests at around 4x120, 1x585 rms.
Would this work and allow me to use "surround sound"? I guess it would be:

channel 1: front left speakers
channel 2: front right speakers
channel 3: back left speakers
channel 4: back right speakers
channel 5: center and rears next to sub
channel 1x500: sub

Also, probably a dumb question but did you have to run new speaker wire to all speakers in the car with the new amp, or did you just use the existing wiring?

My unit is supposed to arrive tomorrow!

Xpresion

that's a very nice find, if my amp dies i will certainly look into this one.

The existing wiring is thick enough. you wont need to run new cables.

You made a mistake with the distribution.

CH1 Front Left
CH2 Front Right
CH3 Rear Left
CH4 Rear Right
CH5 Sub woofer only as you will set this to Low pass frequency (30-100hz).


If you try to run the center and rear parcel shelf speakers of the subwoofer output, you will blow up your small speakers straight away)

As for the center and rear parcel shelf speakers, you will need crossover to remove the bass (low freq), as they will distort VERY easily. Even if you run them with the door speakers, they will distort because the door speakers are component speakers and are designed to accept and produce low freq.

in order to get the center and parcel shelf speakers going, so you will need a crossover box to filter out the low frequency from them.


Alternatively. you can run this setup. and avoid the crossover box.

CH1 Front left + Rear Left
CH2 Rear Right + Rear left
CH4 Center front (crossover set to hi freq)
CH4 2 rear parcel shelf speakers (crossover set to high freq)
CH5 Subwoofer.

Hi.
I'm pretty sure that my SLK got an AMP. I have a COMAND APS NTG with Nav.
Nav unit is in the trunk, certainly connect with fiber optic.

I bougth (and not yet received) this S160 product :
http://www.aliexpress.com/item/Andro...379131688.html

The seller made me buy this cable to bypass amp :



Thank you for the information about GPS cable.

Does anyone know this product :
https://navtv.com/products/NTV-KIT42...mb-opti-1.html

It replace the bypass cable, and allow to use orginial AMP and fiber optic.

Xpresion

ah because yours is the pre facelift. sorry.

The SLK post face lift had the newer COMAND NTG2 i think? it was an all in one unit.

Yes you will need the 6M long cable. and in this case the 6m long GPS cable.

The MOST module you linked is the same as the one on AVIN website for $130.

you can give it a shot, however i was not happy with the sound quality / sound level when i tested it a few years ago.

Silly question. How do you set the time once u have the android heat unit in? The old was setting the clock in instrument cluster via the original headunit. Are their any other function you might potentially loose?

Xpresion

That's Fine mate, if your not comfortable doing it, its a good idea to get someone else to do it for you.

Xpresion

Using the steering wheel control, you can navigate to a menu in the cluster that shows says Date/Time In that menu there is a setting that goes along the lines of sync clock with COMAND unit. if you set that to NO, then it will take you to a time setting screen. after you set the time push the needle that resets the Kms to acknowledge the time / date.

Xpresion, please spoil us with some more videos... Google Maps using Wi-fi or 3G tether, Spotify or Pandora, etc.

I'm still waiting for 2 more wires to arrive. in the meantime I found this youtube video. I'm pretty sure this is the HU...


Gotta love that music!

I'm glad this thread is recent because I found out last weekend that my Comand Unit is bad and it's not covered under extended warranty, so I'm trying to figure out my options. Easiest, but more expensive option, would be to purchase a repalcement OEM comand. I've got a 2009 E350 SS w/ the HK system and Sirius Radio. Just trying to figure out if this will work for me.

I've heard that the 2009 has more limitations than older model w211's on MOST, so if anybody has a "quick and easy" answer for me, that'd be great. I'd have to have a shop install, as stereo install wouldn't be my strong suit.

Hi,
Back in the game.
The original seller and I still have an open dispute.
Order a new headunit from a second seller, better rating and better price delivered.
Strongly suspect the first head unit is dead.
Connect to 12V and its dead, nothing.
Checked with voltmeter 12V is arriving but its not reacting.
Should arrive end of next week.

Cheers, will take some videos

Awvince

Hi,

Can you tell me if the unit works with the instrument cluster, does the radio, navigation instructions and such get sent to the instrument cluster display?

das eighty

Any updates on this fellas?

MeezyAMG

Is there a way to get the cd changer to open after you remove the comand? Would be nice to remove the cd changer and use that space as a hidden compartment. Also did you have to connect the "key1" cable from the harness somewhere? For some reason everything works fine except the steering wheel controls.
