2011 WK2 - Upgrading factory 9 alpine system

Copied and pasted into new thread for my own application.

Today, you can choose from the Alpine Unit which will give you a 5.1 system or the JBL MS-8 with it's 7.1 capabilities which matches the design of your system. So, here, the question you have to ask your self is, do I want to retain the surround or go with a traditional front/rear/sub system. With traditional, the 2 headunits you mentioned will be fine for you unless you require a lot of fine tuning.

The 2nd category is how much fine tuning you want. For that, I recommend to figure out your speaker first. Then you can ask your self how much to I want to improve the sound, I am in the audiophile category where I have to have each speaker time aligned.

The question of overkill is really depending upon your perfection you want to achieve. And no worries, you did not hijack anything.

Keep us updated.

Best for now.
Thank you for your knowledgeable response. I have spent a few days reading from this forum and your insight shows vast quantities of depth. I appreciate your opinion.

Having read all the updates completed successfully on the WK2 grand Cherokee, I've decided to take the path of least resistance and decided to do a traditional setup. Considering the lackluster application of surround sound in the stock alpine system, I am not expecting to notice a substantial difference when going traditional. You can correct me if I am wrong in my assumption.

Having said that, here is my proposed setup.
-Head unit : Kenwood or Pioneer aftermarket. (Still deciding on which model... DNN's or NEX's) Must have Nav, DVD and decent EQ with Xover.

-Amp : Alpine PDX-V9 5-channel. After research, I've noticed quite a few happy enthusiasts that like this amp. It will provide a good base for component fronts, rears and provide sub setup with adequate power. A lot of the research options seemed to pull information from back to 2011 and beyond, so if there is another option that might be better for sound, I am all ears.

-Sub : JL stealth box. Again, having read reviews and other builds, there is a lot of positive responses on this sub setup for sound and space saving. Beyond this option, I may look into fabricating a custom spare tire application and add a larger or better sub in the future to that location.

-Front speakers : Research on this site has shown a lot of positive feedback regarding the Focal line in the ISS690 components. I can only seem to find one location that sells these, but they seem to be a good option for factory installation. Alternatives would include a retrofit Focal 6.5" component application. I'm all ears again, if these are not a good option anymore.

-Rear speakers : Looking at Focal lines, ISS165 which shows listed as 6.75", but actual size is dictated closer to the 6.5". There are a few people that have listed these as good for this application, and that is the direction I am looking at.

-Steering/Factory retention : Going to go with the idatalink rr maestro direction. With subsequent components, It looks like I will retain all my current factory options with no issues.

-Center speaker : Looking to find a replacement for this location, but leave it connected to factory amp. Not sure if this will allow me to keep a good clean sound for phone chatting. I am still unsure which will work best for retaining my voice calling sound.

With your input given above, I think my system will be decent without the need of an external DSP. I believe as long as I go with a really good head unit, the need of external DSP would be a waste of resources in my application.

Also, most likely add a backup battery or cap to keep strong power to the Alpine amp. Research dictates that as power to amp trails off, so does the rated power output to speakers.

Anyhow, thanks for your input and I look forward to anyone else's input regarding a better or more efficient direction to go with my system.

Re: 2011 WK2 - Upgrading factory 9 alpine system

Greetings,

Your welcome and anytime.

If you are going with the traditional system, do not both with the center channel speaker. You are not getting any benefits with it. To truly appreciate it, you do need to have a better external DSP. Moreover, since you have the ability to change the headunit out, run a straight clean path to the amps.

As for the speakers, the Focals are an excellent speaker. The differences is in the tweeter which you a metal material. This will result in a more harsher and bright sound. Thing of a Club system. If this best suites your taste in music, only you know that answer. The other material that is commonly uses as well for tweeter is a soft dome. Silk is the most popular and then their is other fabrics. This gives a more natural sound. Go to a local Best Buy and listen between speakers with both materials. If there is a good shop that is setup with a proper sound board, try that.

Best for now.

Re: 2011 WK2 - Upgrading factory 9 alpine system

Ok, got my stuff ordered. Here is a list of what I have on the way for my build.

-Head unit- Kenwood Excelon DNN991HD
Kenwood Excelon DNN991HD Navigation receiver with Wi-Fi® at Crutchfield.com

-Factory Retention- iDatalink Maestro ADS-MRR
iDatalink Maestro ADS-MRR Interface Module Connect a new stereo and retain the steering wheel audio controls and factory amps in select 2006-up Ford, GM, Chrysler, and VW vehicles at Crutchfield.com

-Front door- Focal Integration ISS 690. 6x9 components.
Focal Integration ISS 690 6" x 9" component speaker system at Crutchfield.com

-Rear door- Focal Performance PC 165. Went with these so I wouldn't have to pull cargo tweets.
Focal Performance PC 165 6-3/4" 2-way car speakers at Crutchfield.com

-Cargo tweets/speakers- Might upgrade with unit and passive xover in future, otherwise not important.

-Dashboard speaker- Disconnected probably per advice.

-Subwoofer- JL Audio Single 10" Stealthbox.
JL Audio Single 10" Stealthbox® (Black) Custom-fit enclosure with 10" W3v3 subwoofer — fits 2011-up Jeep Grand Cherokee at Crutchfield.com

-Amplifier- Alpine PDX-V9 5 channel
Alpine PDX-V9 5-channel car amplifier — 100 watts RMS x 4 + 500 watts RMS x 1 at Crutchfield.com


Quick question for those that have used this same alpine amp. I read that a few of you guys that have used this amp put it under a seat. Are there any other places that this amp would fit that you noticed on your builds?

Also, Im assuming that with all the bells and whistles I have in my overland summit, I will need to keep the factory amp connected and in its location. Am I wrong, or could I potentially replace it with the new amp on the left side of cargo opposing the sub?

I haven't pulled my jeep apart yet, so I thought I would pick your brains.

Thanks for your help and consideration!

Re: 2011 WK2 - Upgrading factory 9 alpine system

Greetings,

My factory is seating in my closet. Where the amp was is my 2nd battery for my amps.



So far, no problems and I have had serval update performed by the dealership without any problems as well.


Best for now.

Re: 2011 WK2 - Upgrading factory 9 alpine system

Not to hijack the thread but im doing almost the same thing to my jeep and just wanted to know where I could place two amps without being seen? The only thing I really want showing will be the sub box. Ive seen some people take out their spare tire and mount the gear in that space but Id like to keep it.

MurderME - Did you add the Maestro CH1 also? It retains the stock camera. Or are you using some other aftermarket cam?

Funny... i just finally recieved all my components for my build and am sitting in the jeep now looking at tearing open the dash.

I just today looked at amp locations and found beneathe the front passenger seat to have enough space to accomodate my 5 channel alpine amp. The only issue was low hanging power seat wiring and two metal mounting points that i opted to bend up and away from my amp. I also zip tied the lower hanging factory wires up so they wouldnt drag over the amp in lowest seat setting. This location seems to give the shortest and most convenient power wire run to the battery (battery located in compartment under the same seat). I have the summit version which has the seat cooling and heat. Other models without the seat options might have more room.

As for the camera. I am going to utilize the maestro ch1, avch1 system to retain all my factory controls. I havent hooked it up yet, but i will post results after i do.

Furthermore, i designed a system of relays and sequential switch to integrate a three camera system using the single trigger, single backup camera option on my kenwood head unit. This system will have left and right blind spot as well as backup, all being triggered by respective left turn signal, right turn signal and reverse signal. I will also be adding a 4 channel direct overide so i can switch any view on as desired. My circuit is designed, but parts have not completely arrive, so i will repost with updates once i get this installed.

Good luck on your install, im hoping mine will be event-free.

Re: 2011 WK2 - Upgrading factory 9 alpine system

Thanks for the info. I haven't opened the compartment under the seat yet, but once I have the few things I'm waiting on to arrive I'll be investigating a bit more. Im having my gear installed by a shop that's very reputable in my area. I just want to figure out what exactly I want done and location. If they suggest something better, then it's all gravy.

I would love to see that multi cam set up when and if you post it. It sounds awesome!

Re: 2011 WK2 - Upgrading factory 9 alpine system

I know this thread is old but:

Can I run TWO class D Alpine PDX amps in my 2011 WK2 Overland without adding a battery and cap???

Is anyone doing this without any added electrical components (battery, cap, etc)???

I have a PDX-M6 amp for my subs and I'd like to add another PDX-F4 or PDX-F6 series amp for my 4 other channels. I am planning the entire project and trying to decide if I should go with just one PDX 5 channel amp or two separate ones. I'd really like the extra power of two

If I really need the extra battery and cap (I think that's what I see above) then can someone explain the install? Is it easy? Do you just connect the extra battery to the factory one???

Please chime in if you know anything about this! I have an engineering degree and a basic knowledge of electrical connections but I have never added a battery and cap...

THANKS FOR THE HELP

Re: 2011 WK2 - Upgrading factory 9 alpine system

Greetings,

The questions are how many subs are you running, what size, how hard are you going to drive them and how are they wired up? Typically, sub amps draw the most current as you already know. As for the other amp to drive the other 4 channels that should be fine.

With the right 2 amp wiring kit, it should not be a problem. If you feel that your sub setup is going draw more power that you initial anticipated, a quality cap would be needed for the PDX-M6. Or go the extra margin and get a 2nd battery.

In my setup, I am running 3 amps which comprises of 1 sub amp and 2 other multi channel amps on a secondary battery. The other advantage I have, if I replace an amp and up the power, I know that I am safe.

Best for now.

I am still not sure about the subs. I thought I may try to find a good deal on something used. Either one or two high end 12" woofers. If I can't then I'll probably just run one 12" ported. Either way I think I'd like to have the amp running at 2 Ohms???

If I just wanted to stick with the PDX-M6 and the PDX-F6 setup would running one or two 12" at a total load of 2 ohms be too much? What would be a reasonable limit? Do you think the PDX-M12 and the PDX-F6 would be too much???

Thanks a lot in advance for anyone's input

Greetings,

Based upon your setup, if you are driving the sub loud and hard, then a Cap would be recommended for the PDX-M6. Remember, are still using the factory amp and is still taking power from the electrical system if you are getting the signals on the output side for upgrade and the other speakers not being upgraded. You have to figure your load for 3 amps running all time.

With the PDX-M12 I would for sure put a cap or go with a battery option. As effect as Class D amps are, you do not want to strain other car systems that rely on electrical current.

Best for now.
