Re: Upgrade stock 6 speaker system on 2015 JGC Limited

1stjeep-really appreciate the advice. Put the alpine spa-610c in the front and already sounds so much better. Working on the back tomorrow. Oh how did I miss the silk dome tweeters! Man, the stock speakers are absolute junk. Planning to add the kickers in the back. Will take some pics and post soon.

Re: Upgrade stock 6 speaker system on 2015 JGC Limited

Installed JBL GX602 6.5's in the back based on some feedback that they provide good bass. Not getting any bass at all from the rear, nothing even close to the punch I'm getting from the Alpine sps-610c in the front. Took one out and installed a Polk DXI-651 (suggestion from Best Buy) and still the same, no bass from the rear. Stumped?

Also, looking to add the Alpine PDR-V75 amp to power the 4 speakers and JL Audio stealthbox sub. Heard good things about this amp and think it will fit well in the spare tire compartment (taking out one of the storage boxes). I want to catch everything at the radio (speaker output to the amp and amp output back to the speakers). I'm trying to find a m/f harness to go between the radio connector and the radio so that I don't have to cut into the factory harness. Metra, etc. does not have one for the 52-pin harness. The closest thing I found was: Metra Online but this is only the male side and I also need the female. I also found this company: iCarKits - V8-AVICH-03 for the 2015 JEEP GRAND CHEROKEE. which is an unlock for nav, etc. Reaching out to them to see if I can buy just the harness.

Any thoughts?

Re: Upgrade stock 6 speaker system on 2015 JGC Limited

Not getting any bass from the rear door speakers probably has to do more with the door enclosure than with the speaker. I didn't get much bass from my 2004 GC rear doors when I upgraded the amps and speakers. Also, my factory speakers in the rear of my '15 GC don't throw out any bass what so ever. Rear door speakers are usually just for sound fill. Use the fronts for mid-bass and a rear sub for lows.

Re: Upgrade stock 6 speaker system on 2015 JGC Limited

Hello!

I'm not looking to dredge up old stuff, but I am looking for some clarification, as I've read different responses, in different forums.

I very recently purchased a 2015 GC Limited, with the 6 speaker set-up. Years ago, yes, I used to add outboard amps, big speakers, etc, but I'm getting a little too old to be on my back, straining to reach obscure wires under the dash, and these days the radios are way too integrated into the vehicles' controls, so you can't swap them out anyway.

I listen primarily to classic rock, don't really need a "sub", and would like to do a few minor upgrades to my OE speakers, so that's why I'm here. I've read that there are "Chrysler, Kicker" upgraded speakers, "Kicker, Kicker" speakers that are similar to the Chrysler upgrades, as well as other brands. One question that popped up while reading various discussions, is that the Kicker speakers that are sold through normal stereo sources, are a higher quality speaker, than the MoPar Kickers. Does anyone know that to be true? If so, are the dimensions of the two speakers (6x9) the same? In other words, will they fit in the front doors of a GC?

Secondly, do the Kicker tweeters directly replace the OE tweeters that are mounted in the "pods" on the upper portion of the doors?


Thanks for any information that you guys can provide!

Upgrade stock 6 speaker system on 2015 JGC Limited

Any upgrade you make to the stock speakers will be better. I've put Alpine sps610c in the front and 610 in the rear. They sound much better than stock speakers. The component tweeter fits inside the existing pillar, no modification other than put some hot glue to secure if needed. Not sure if kicker components fit, think I read on one of the posts that they fit great (or maybe these were the focals)?

Taking the front/rear panels off fairly easy. Panel removal instructions are all over the board or check wk2jeeps.com.

You will probably want to add sub. There is one oem-like option which is the jl audio sub box. It fits in the rear right quarter panel and looks stock. The downside is it's $700, and you still need to add an amp. I'm working on a cheaper solution for the sub/box now and hopefully will have it complete soon.

You probably need this type of a harness:

Re: Upgrade stock 6 speaker system on 2015 JGC Limited

Greetings,

If you have a 2014+ with the 8.4 or 5.0 screen, the Uconnect system is built into the radio itself. On the 8.4, besides the radio functions, you have other functions that the JGC performs on the touch screen display and those data signals travel thru the Hi-Speed CAM Bus via the Uconnect. This is the major problem with these radios to change out to the aftermarket world.

Check with Cruz first and make sure you are compatibly. In this industry, this change quickly, so it hard to keep up to date. If this was the case, it would make cleaning up this system so much easier and user-friendly.

Those who have the 2013 and below have a far easier time.


Best for now.

Re: Upgrade stock 6 speaker system on 2015 JGC Limited

Finished the upgrade to the stock 6-speaker system (at least for now):

F: Alpine SPS-610c
R: Alpine SPS-610
Sub/box: JL Audio 10W1-4 and custom box to fit in spare wheel well
Amp: Alpine PDR-V75
Harness: PAC-CH41

F/R: Installed the F/R speakers as per the many instructions on this forum. Sounds much better than stock speakers! Tweeters fit nicely in stock location using stock grill.

Sub/box: I used the JL Audio 10TW1-4 sub (I think same one they put in the stealthbox). Got it for $185 at Crutchfield, not bad. I didn't want to spend $700 on the stealthbox so I got the idea to build a custom sub box to fit in the full-size spare wheel well in the trunk (see pics). The total interior volume when finished was about .35 cuft (after adjusting for displacement of the sub). This is small but is the approved spec for this sub. Added 1/3lb poly-fill for some assistance. Relocated the jack/tools under the rear drivers side seat. Fits perfect even when seat it down.

Amp: Installed the Amp under the drivers seat, fit very nicely. Power to the amp goes up carpet on drivers right side between seat and center console, through the center console (nice chase once you pop out sides of center console) and down right side center console between it and the passenger seat right to the battery compartment. Ground connected to bare metal screw on left side of center console towards the gas pedal (will see it once you pull off the left side panel of center console).

Connection to radio/speakers: I used the PAC-CH41 interface ($200 on Amazon), not for the NAV unlock features but rather just to get the harness in order to tap into the factory signal coming out of radio and then back to the signal going to the speakers. Expensive for just the harness but I couldn't source both ends anywhere (only could find the female end as posted early) and I DID NOT want to cut into the factory harness. Worth the investment to me.

Haven't done much tuning yet but so far sounds great. Few questions:
- The volume gets really loud at 20-25 volume on the radio. It starts to distort at 30+ and is way too loud. I have the gains on the amp turned to minimum. Should I install a LOC between the radio speaker out and the amp rather than just going speaker level into the amp (which can accept speaker input)? Would this allow me to "clean" the signal a little better so not to distory and also keep from blowing my kids ears out if they accidentally turn it all the way up?

Re: Upgrade stock 6 speaker system on 2015 JGC Limited

Installed a PAC LP7-4 LOC and the the overall volume control sounds much better. The incoming signal to the Alpine PDR was just too hot even with gain all the way down. Volume on the system got too hot at only half the volume level and really distorted at 3/4 volume. Now, volume sounds much better from low to high.

Interesting, I think the HU is cutting off low frequencies to the rear. When I have the PDR using channels 1-2-3-4 for sub input and I fade to back speakers, the sub almost disappears. When I fade back to front, the sub comes to life. Right now, I'm splitting front input to sub. I'm playing with the sub gain and EQ to get it right. I'm impressed so far with the homemade box in the spare wheel well. Really kicks.

The front Alpine SPS-610c's are really harsh. I've cut the treble down to -4 to -6 just to compensate. I am planning to replace these with JL Audio C2-650 components and cut the on-board crossover to -3 since the tweets are at the pillars. Looked at the Image Dynamics CTX-6.5c's but ended up with the JL's after reading on them. Any advice?

Upgrade stock 6 speaker system on 2015 JGC Limited

There is no external amp with the 6 speaker system. You would have to tap into the speaker outs for your LOC.
