I'm not sure how it was setup but I'm enjoying every bit of the new sound!

The answer to that is yes and no. This is based on your own perception of sound.

With the Stealthbox you will finally hear the lower frequencies and a richer bass sound that does not get drowned out and lost with the stock. The factory DSP for the sub cut off is estimated in the area of 55-65hz which will work pretty good with the Stealthbox. Yes, this is an improvement here.

Now, with the lows changed out you might find the front door setup becomes even weaker. Again, this is based on your own perception of sound. Many here have swapped out both stock front door speakers for new ones and went with a 6.5 driver as opposed to a 6x9. A few posts up are links to the difference between the drivers.

Tweeter selection is based mostly on the type of music you like. Focal tweeters have a metal based sound that is tinny and bright. That is good for club music, pop, hip-hop, some rock. The other type of tweeters are a soft dome type of material that gives you a more natural sound. A few posts back is some references on the types of tweeters to help you determine what best for you.

IMHO, the factor here depends on how long is your lease for and does it pay to invest in the upgrade. Also, another key point is how much time do you spend in the JGC listening to the music. They way I would approach this is by changing swapping out the front door speaker first and after a month or so when the speakers break in, determine if that is all you need. Figure for this first step to spend around $350.00 for speakers plus the install. Then after that you want the bass, then go for the Stealthbox.

If read the various threads and posts, to correct the Alpine system does require spending some major Benny's to correct it.

Best for now.
Are you saying running the stealthbox off the factory amp. Cause I was looking to see if that was possible.

Greetings,

The post that I was replying to was for both the Stealthbox and the aftermarket amp in a leasing situation.

With regards to your question running the Stealthbox off the factory amp, you will get sound out of it, but the impact that is was designed for will be totally missing. Some of us believe the amp is pushing around 100 watts total power at 2 ohms into the factory sub. Personally, I would not recommend this approach. Any Class D mono amp that can push over 300 watts rms at 2 ohms is the best bet. At 500 watts rms, you will be in heaven.

Best for now.

Today I installed the Stealthbox with JL Audio 500 watt mono amp. If you are looking for powerful crisp base this is an awesome mod. I was blown away by the improvement with sound that compliments my focal front and rear plus Polk Audio center speaker. The custom design of the Stealthbox looks like it is right off the factory floor.

Congrats! how easy/hard was the installation of the Stealthbox + Amp?
I know it's not easy as replacing door speakers but what kind of work it requires? What part/panels of the interior must be removed and if any extra wiring/electrical work required?

Back door: Alpine SPR-60
Amp: JL Audio XD700/5v2
Summing Device: PDLC81 Pac 8-Channel Digital Line Output Converter - PDLC81
Sub: JL Audio CP110LG-TW1 JL Audio CP110LG-TW1 MicroSub™ ported enclosure with one 10" TW1 subwoofer at Crutchfield.com

Very happy with the quality! These Alpines sound way better than the Focals.
Quick question. Did you install SPR-60c or 50C. The link is for 50C??

Also I want simplicity and am considering the focal ISS-690 but don't want a harsh sound from the tweeter. I have no plan on installing an AMP. Does anyone else have any recommendations for just a pure stock swap that will be noticeably better?

I installed the ISS 690s into my Altitude (standard 4 speaker stereo) and found the replacement to be wonderful. With the low sensitivity rating, I believe that 95% of people would be perfectly content with just replacing the speakers without installing an external amp. The lows are strong and tight, (Killing Strangers from Marilyn Manson shakes the outside mirrors even after dynamatting the doors), the mids are very good, and the highs...can be a little strong, but are very crisp and bring out details I never heard in songs. I do have the treble set at -2 also, with mid flat and bass at +1. You do have to turn the stereo up to about 15 though to start getting decent bass response. I had considered going with a silk or soft dome, but I'm afraid of losing the detail and crispness.

It is also nice that they bolt right up without custom spacers or other hoopla.

Also, after installing the speakers you really get an idea of how crappy Sirius/XM music reproduction really is compared to songs from a SD card. Sounds like they are playing the songs through mud.

I have a JL 700/5v2 and Infiniti sub that I'm installing during some time off at the end of this week.

What does anyone think about pairing the Polk DB351 center channel to the Polk MM6501 component speakers in the front doors. The speakers are factory replacements for the Alpine stereo in a 2014 Durango RT. Thanks for the feedback.

Re: Focals ISS 690, ISC 165 & Polk db351 install tutorial with pics

Greetings,

Both Polk's for the tweeter's have a soft dome material for a more natural sound. They will be pretty much even in terms of tonal respondence.

Best for now.

I will take pictures tomorrow. And hopefully some sound clips as well. I had the geeks at Best Buy install the sub with amp. The amp is under the driver seat. I installed all the other speakers.
