Greetings,

You can try this model and it is a good price point:

Polk Audio db6501 6-1/2" component speaker system also fit 6-3/4" openings at Crutchfield.com

If you want to step up into the $250 - $400 range, look into the Helix, Infinity or even Rockford Fosgate. The tonal response is not that different. Just remember, you have no ability to properly control the front stage with the factory DSP/Amp.
It will work and meet your requirements for now.

Best for now.

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

Hey man, just wanted to stop by and say thanks for this write up. Was a huge help. I finally got mine installed and shared my feedback HERE: Alpine 9 speaker system Speaker Only Upgrade results
Figured i'll post it here as well for others to see different people's opinions. Keep in mind my system was the 6 speaker stock setup on the '15 JGC Limited. Thanks


At first I was way disappointed. They sounded just as bad as the stock speakers as far as clarity. Luckily from reading up, i figure I'd let them do their "Break in" and glad i did.

Start with the Install:
Install was a breeze using one of the other forum topics that showed step by step and pictures to go along. The worst part was putting the molding around the door. For the tweeters, it did take a very little bit of sanding to get the Focal's in, but it wasnt enough to break the stock tweeters from going back if needed which is what i wanted in the event i wanted to reverse the setup.

SQ:
After install as i said, they sounded bad. After some time to break-in however, i am really happy how loud and clear this set is. I'm assuming based on the high 92+DB sensitivity rating that it made it possible to sound louder then stock. Of course the type of music and source you're playing will make a difference. Some source or songs will sound low, while others are thumping.

Bass:
Gotta say, i thought the stock bass hit decent. Moving to these i would say slightly improved with maybe more quality. I can't really say however if the bass is actually stronger or not. But either way i am happy with it. (I'm still planning on adding my sub to the system later on if that says anything haha )

Tweeters:
OK so here is my complaint on this set. First let me say, clear as day. The quality is there. The problem i have with this set as i have heard this throughout the forum is the "Brightness" of these tweeters. I mean i like my music loud, but the brightness of the tweeters in certain songs actually hurts my ears! Even at lower volumes it can still bug you. This is where i heard people chime in about Silk Dome tweeters. I wish i had a way to test different sets, but not that simple. Will i return the set because of this? So far no, and probably won't, but it's been on my mind.

Overall:
Well, i can't say i'm not happy. The speakers do sound nice, and it has improved my audio experience. Am i saying i can leave it as-is? No. Everyday i been looking at amps and signal kits because the SQ still needs work. I wish there was an easier way to update the EQ part of these systems to improve the SQ only, but not the case. Would i buy these speakers again at their pricey price tag? Honestly I can't answer that. I wish i would have been able to test other speakers to truly see the difference. Because of this i cant answer that question. I purchased mine from Crutchfield which does offer a return policy. But since i cant see the effort being worth while and returning something i've been using i am not going that route. All i will say is I did think it was worth replacing the speakers though

So that's my take. Feel free to ask questions. My music type mostly is Dance, Club, Techno, etc.. A lot of Dance style music. Of course i listen to others as well. This is probably why the tweeters are not a great fit for me but oh well... Happy listening.

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

Really appreciate this thread. Wanted to clean up the muddy stock system for my wife's GC without going overboard. I started with the ISS 690s up front, huge difference. They were pretty bright so I tweaked down the treble. I didn't think the rear door speakers would do much, was surprised how much of a difference the ISC 165s made.

Next I replaced the rear D pillars with DB351s, ouch, way to bright. Not sure if they had compensated with higher level highs because the stock speakers had bad response, but the highs were too much and not impacted by the equalizer. I ended up cutting the tweeters out and problem solved. I would not recommend replacing these.

I replaced the center speaker with the DB351 and it helped a little. Seems the center speaker is used even with surround off, it impacts separation so wish it could be disabled. The sound was now much clearer and very bright, it was actually painfully bright after some full volume songs. I replaced the Focal tweeters up front with Polk DB1001s, the sound is now perfect and the wife is very happy!

It's not a window rattling, super loud system, but it is decent and is night and day from the stock speakers. For those with a lease or not wanting to spend a huge amount on audio, I highly recommend this setup.

Also keep in mind as others have mentioned, Sirius radio is not the best quality music in any vehicle, probably due to the compression. You'll need an iPod or MP3 player to get the most out of the stereo.

Greetings and welcome,

The rear pillar in the OE system should have been setup as a band-pass crossover point. Instead, the use a full range speaker with a lower high frequency range. I am not sure where, but ideally anything under 16k hz makes a big difference.

Even through you cut everything off from the upper midrange to the high's, it perfectly fine with OE Factory DSP setting. Your method help balance out the rear door.

The main thing, if it works for you and your happy, then smile and drive while listening to the tunes.

Best for now.

There seem to be 2 versions of the ISS 690, one single way, another 2 way. any cons to the 2 way ?

Component speakers usually sound better and also you have more control over the placement of each speaker/frequency. If the car is setup with component sets (for example front of jeep has woffer in door and tweeter higher part of the door) this is where the component setup works better. But for the stock 6 speaker setup for example where the rear doors are the only speaker location, the link you provided would provide an easier install since you wouldn't have to mount the tweeter in a custom location. (These would not fit in the rear, just an example)

I'm still learning a lot about this so hopefully some others will add their comments as well.

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

BTW the focal tweeters are so bright in the ISS 690 component set, that it might be a good idea to stay away from installing a second set in the rear. When i'm rdy to upgrade the rear, i might look into a set where its more of a driver for MID range or a full range speaker with less higher frequencies ranges. IDK i need to do more research

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

Greetings,

Rear door and Rear D-Pillar would be to bright if you have the Alpine Premium System. For the stock 6 speaker some say it also to bright. But if you find a cap to it, you can cut off some of the real top end of it.

Wide band full range speaker or a mid range drivers are the best for the d-pillar. IMHO, if you do not want to run a club system, the wide band full range for the rear door works very nicely.

The speaker configuration for the Alpine and stock (if you need the sub, then you have to throw it in) is the correct design. However, the OE specifications for speakers is another story.

Best for now.

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

Hi all,

Has anyone added an amp and sub to their stock 6 speaker systems?
I'm looking to add my old JL 500/1 and Type R sub for a little more kick. Does anyone have pics and a step by step i can follow? Thanks

I kind of have a question on this as well. Those that put in an amp for a sub/stealthbox, did you tap in to the subwoofer amplified signal (between amp and speaker, connector D3804B Pins 3 and 6) or a full range amplified signal(between amp and speaker, doesn't matter which)? Or did you tap in before the amp on a full range speaker and use a cutoff frequency on the amp? Also, for mounting underneath the seat...where did you tap in to the harness? Back by the sub? Where the amp is? In fact...I don't even know where the factory amp is located. HAHA

I dont have the AMP, but tapped into both front speakers right after the radio. Word of advise, yank the plastic around the radio from the bottom if you do this.
