Since this was a couple years ago, I have since upgraded to components. Main reason was that I was still wanting better front staging with a touch more low end, but nice and tight, plus more volume. They (RKST in Pontiac, Michigan) used 1/2" mdf for the front 6.5", and centered it to boot. With the advent of the Helix P-DSP 8 Channel audio processor, I was finally able to keep the loaded up RER I have and the Boston amp, leave all that intact, and just branch off the rear full range audio outputs from the Boston Amp as inputs to the Heilx. Post Helix, you have full range audio that can be sent to 8 different channels, with up to 31 bands of EQ applied to each channel. Not to mention selectable slope crossovers, time alignment, phase selection, etc. You name it, it does it. Best money I ever spent on audio equipment (other than the dampening material) hands down.
That's a ridic system you have there! I'm probably adding a amp to bypass the factory Boston amp and keep my REC this summer. I'll probably just stock with Fosgate though.

Re: Fitting Infinty Kappa 6x9 in the Front Doors.

Thanks I recommend you get the Helix Processor, no matter what you do. Even if you just add an amp, little of this, little of that at a time. You will always have it after the purchase ('cause it is a bit steep) and it just makes everything sooooooo much easier. Plus, if you ever sell the WK or what ever, you can remove it and take it to the next vehicle you have.

Re: Fitting Infinty Kappa 6x9 in the Front Doors.

Curious on your speaker selection.

What Infinity Kappa models did you purchase?
I noticed that the 6x9 you purchased are two way. Does this not defeat the purpose as the stock Boston amp only sends woofer signals to that speaker, per all that I've read. Is this correct? or if not, does anyone know the actual frequency response of the signal that the BA amp sends to the door speaker channels?

Also, are there any mounting depth issues with 6 1/2" speakers in the rear doors?

And finally, how did you hook the basslink input to the system?

Found the answer to my basslink wiring question @ Sub Install with stock radio!

Where did you locate the basslink in the vehicle (most put them under seats)?

Also, while using a Line Out Converter will get the Basslink going, is there a better newer method (something that plugs into the factory harness behind the radio, and adds in RCAs outputs and, if possible, a remote wire)?

Re: Fitting Infinty Kappa 6x9 in the Front Doors.

Because at that time I could not find a 6x9 component setup where the 6x9 was a dedicated midbass woofer. Not saying there aren't any, I just did not find any at that time. As previously mentioned, the 6.5" components are more than a match for the 6x9's that were in there. Last time I read internet gossip on the subject, the crossover for the front 6x9's in the Boston system were 250Hz LP 12db per octave. Not sure as to the type of filter. Rear doors are full range. Front 3.5" were 250Hz HP 12th order. This of course is just from the internet reading. You'd need to put a scope on the amplifier outputs to really measure it. I never bothered to really find out, since I knew the rear doors were full range, that's what I used to feed the Helix. I hooked the Basslink at that time using the speaker level input instructions from Just For Jeeps in the install of the kicker Sub. I tapped the left front speaker for the signal, just like the instructions for the Kicker system, only instead of their sub, I used a Basslink. After that, just ran power and ground. No need for remote, set the Basslink for autosensing for the turn on. Whole setup sounded good, step up from the factory Boston, for sure. But, as time went on, I saved some cash and wanted to take it up several notches, thus the full house JL setup.

Re: Fitting Infinty Kappa 6x9 in the Front Doors.

Running into the same issue with my ref 6x9 about the 1/2 spacer. Here are some thoughts .Stack a few nuts up and take some speaker tape or a caulk gun and go around the speaker to fill up the 1/2 gap with silicon? Or does anyone else have a suggestion ? Just installed a pioneer Appradio 3 swapped the dash and the rear speakers for infinity refs. Kept the stock Boston amp. Or instead of all this mod work on the front doors to make the 6x9's fit,,,am I better off sticking the 6 1/2 inch refs in with the adaptor plate that fits ? Will I get enough bass up front out of the 6's with the Boston amp? Not looking for rattle your windows base just a well rounded sound.
Or do I just keep the Boston 6x9's in.
This is for a 2008 GC

I did just find this site that has half inch spacers for 6x9 speakers
http://www.car-speaker-adapters.com/...id=spacer_list.
Anyone use these??

Re: Fitting Infinty Kappa 6x9 in the Front Doors.

My opinion is that until you add an amp and/or change the system EQ, I'd keep the factory Boston 6x9.

Re: Fitting Infinty Kappa 6x9 in the Front Doors.

Hmmmm speakers are coming from amazon tomorrow and I ordered that 1/2 spacer this morning. Should I go for it or return the speakers to amazon and just eat the spacers which were only 14 bucks

Re: Fitting Infinty Kappa 6x9 in the Front Doors.

I can tell you that pulling the door panel (to me) is a pain, and therefor I would want to do it as little as possible. I also recommend every time you do it you have new, factory fasteners. No to mention, put some Dynamat (or any good quality sound deading material. Mine was made from company called "Wirez", and the shop showed me that next to Dynamat-same stuff, different name)) down. It doesn't have to cover the entire door like mine, as just a few sheets on the speaker opening and surrounding area will make a noticeable difference. Another option is if you want to keep the Boston amp, and you don't ever anticipate upgrading in amplifier power or system EQ for quite some time, is to replace the Boston 6x9 with the factory Kicker 6x9 upgrade. It's straight up plug and play, has the correct mounting baffle and connector already on it, and it's a straight up mid-bass speaker. Keep in mind the factory Boston amp and the Kicker amp upgrade are all putting out the same power-288 watts. The difference is that the Kicker amp has the Surround Sound, different EQ and the line out for the amplified Kicker sub that went behind the rear seat. Ultimately, you'll have to decided what route you wanna go.

Re: Fitting Infinty Kappa 6x9 in the Front Doors.

OK I looked for just the kicker 6x9 but only found them bundled with the dash speakers. I already got infinity ref dash and rear door speakers. So I guess I will just return the 6x9 speakers and stay with the Boston's in the front door. I have 150k miles on the jeep and hope to upgrade in another 50k. Granted they are mostly highway miles as I drive a lot to Alabama,TN and SC It runs great and no major issues
