Subtle Overland Sound System Upgrade

Is it possible to substitute the equivalent speakers in a 14' Overland with those from the HK sound system found in the Summit/SRT?

Re: Subtle Overland Sound System Upgrade

Greetings,

That is a good question.

The Alpine amp for the mid bass and other speakers is a 4 ohm load. If the speakers in the HK are geared for 2 ohms, you be having a lost of power with the Alpine system and increasing the volume to compensate. You are better off getting aftermarket speakers that has better sensitive rating of 90+ db. Many here have done this straight swap with excellent results.

Here is an interesting thread regrading the factory frequency response of the factory Alpine OE system. This might help you in selecting speakers. As far as I know, nobody here has done the same of the HK.

Factory Frequency Response

Best for now.

Re: Subtle Overland Sound System Upgrade

Greetings,

Based upon the latest information from the thread From the horses mouth on the Harman Kardon System the speakers are most likely 4 ohms. The problem I see swapping them into Alpine system is their enough power to drive them. The HK speakers are match to that amp.

If you decide to do the swap and it not working out, you can always add a multi channel amp to the speakers that you want to drive louder.

Best for now.

You can do much better with replacement aftermarket speakers as an upgrade to your OEM stereo system. Those Kickers may be of slightly better quality than the OEM Alpine speakers but are not anywhere as good as some the Hat, Focal or Polk alternative replacement speaker choices out there.

These 6X9 Focal components drop right in the front door speaker cavities, and are an excellent upgrade for WK2 front door speakers;

Focal Integration ISS 690 6" x 9" component speaker system at Crutchfield.com

And the included component tweeters will drop right in to the OEM tweeter mounting points on the front doors, completely plug and play. The Kicker 6X9 front door component speakers you linked too don't appear to be able to mount correctly in the OEM WK2 tweeter location.

For the rear doors many have tried these;

Focal Integration ISC 165 6-3/4" 2-way car speakers at Crutchfield.com

Or these if you want to spend a little less;

Polk Audio db651s 6-1/2" 2-way shallow-mount car speakers at Crutchfield.com

Re: Subtle Overland Sound System Upgrade

Greetings,

The difference between the Focal and the rest of the speakers in the list come down to the material of the tweeter. Focal and others use a metal based material in the tweeter dome. The others use a soft material such as silk or another type of textile.

Tweeters come in different types of dome material to replicate the sound and this is were you come in. A Focal tweeter that comes with the component sets has a metal or tinny sound and it has more of a bright sound that sounds harsh to some. Best example for this, if what to replicated a dance club sound or the modern hip-hop, electric and various similar types. The other type of tweeter is a soft tweeter that has some sort of fabric such as silk or something similar. The sound is a more natural and very crisp. Music like Rock, Soft rock, easy listening and jazz are excellent choices for this type of tweeter.

Now remember, we all hear differently. So what excellent for me might not be good for you and visa verser. Pop into a local BestBuy and do a comparison test between the different tweeters that come with the component set.

Best for now.

Re: Subtle Overland Sound System Upgrade

Awesome advice everyone. Thank you very much.

I will likely go down the aftermarket route, though, for my personal understanding if I were able to get the HK amp along with the speakers would that be plug-n-play as well? I know of someone locally that might be upgrading their SRT HK .

Greetings,

First, make sure that person lets you spend some quality time listening to the HK system with your own source material. If they do not have the CD player, the next best thing is the USB stick with you own source material loaded onto to it.

Here is a check list question to make sure you the HK system is for you. Do I want a traditional front/rear/sub or a surround sound system?


The following 2 wiring diagrams should be reviewed to make sure that all the pinout from 8.4 headunit that is matched for the HK. You must physical review the wiring. In the past, some diagrams did not match the color coding that was physical within the GC. So in theory, it should be a very close match.

Re: Subtle Overland Sound System Upgrade

I test drove a '14 Summit extensively and I was more than satisfied with the HK sound, even from my less than optimal sources. In fact it exceeded my expectations of what a factory sound system should deliver. While doing comparison drives with competing models in that price range, it was one of the best if not the best to my ear.

If I had chose the Summit, audio would not be on the radar but I liked the looks of the Overland trim better and going in I knew that the I would want to address the sound quality at some point. If I can keep the upgrade cost at less than or equal to half the difference in the price of the two trim levels while retaining the stock look then I would consider it a win. That sets my budget ceiling to $2K.

I am no audiophile but it seems to me in this day and age the amount of wattage the stock amp pumps out should be enough to fill such a small space with crisp clear sounds. I do not care for excessively loud music, but I do enjoy hearing every detail that is meant to be heard. I never cared for going to a concert to have my hearing numbed for the next couple of days. I appreciate listening to bluegrass, alternative and classical sounds where I can picture the individual instruments being played.

If I can get the stock system out of the mud then I'll be good to go. I will likely replace the center speaker with the popular Polk offering, DB351, unless there is a Focal or HAT equivalent. Not sure if the center adds much to the overall sound stage, I've read varying reports from other members on the matter. I have also read that an application of Dynamat will do wonders and I'm sure that will take the install from being plug-n-play to an undertaking.

Again, I thank everyone for the great advice.

Thanks for the link. I was surprised at the reasonable looking results since they don't match what my ears tell me which is the whole thing sounds muddy.

Greetings,

Anytime.

Four problems with the Alpine system:
  1. Chrysler gave Alpine the specs to follow.
  2. As I have been saying, the DSP is setup just to get by with the masses and you picked up what many here complain about. The muddiness.
  3. The speakers are nothing to write home about. Off-axis response is not present and it is critical in the interior shape of the JGC. For us who are into real sound quality, forget about it.
  4. All of the above.

When I was doing my install, we put all the new speakers in connect to the factory amp. It did not sound that bad, what really came to light was how bad it was crossover at and the delays. Of course with my up level speakers, amplification is needed to make them sing.

Depending on how you want to upgrade the surround sound system, their are many paths you can take.

Best for now.

Re: Subtle Overland Sound System Upgrade

When I traded my Jeep in, I removed my aftermarket center speaker (only one changed), and put the stock one back in. I immediately noticed a significant change (for the worse). I didn't even tell the wife, and she noticed it also (and she typically does not care, or have a clue about SQ). It's a very quick, inexpensive upgrade, and the only easy one.
