Just wondering, do you HAVE to have an aftermarket head unit for upgraded speakers to still sound good?

Exactly! That solved TWO problems. Let me explain.

.... I wrote technical manuals for a living, so GIGO instructions and errors are a particular sore spot with me. Folks, the complete answer is, "Connect the remote wire from the radio harness to the power antenna wire of the vehicle harness". :crash:

Now, a peculiar side effect was that the four speakers came alive like never before. If you look at the hokey way this thing is wired, the speaker signal is split between the speakers and the amp - my theory is that if the amp isn't turned on, half the circuit is open, and the speakers are getting half the wattage.

No 10" subs, no external amp; just a change of one wire. Sounds phenomenal. What a difference a few words and one wire make.:doh:
SO.... here's a question.
(first, I have a 2004 Wrangler)
Just got a new head unit (Alpine cda-105) front and soundbar Infinity reference speakers (4" and 5-1/4") and I am having a similar problem... they sound a little weak.... they highs sound great but the lows are a little lackluster. To be expected from 5-1/4" speakers so I'm not too worried....

HOWEVER... I will be adding a kicker solobaric L7 10" subwoofer and a 500-watt Kicker amp later this week when it arrives....

My factory console-sub has never worked for me with the factory radio installed. It still does not work with the new head-unit.

My question is this.... How would I bypass the factory sub(amp?) completely and which wire on the head unit am I connecting the remote wire from the Kicker amp to?

I connected the blue wire from the Crutchfield Chrysler adapter to the blue/white Alpine adapter wire, (or was that Vice Versa...?) as advised by Crutchfield. Is this is what you were talking about doing in the quoted text above?

Ok.... that was long and confusing but I hope someone can help...

Thanks! :punk:

2006 wrangler stock cd player

Im hooking up my amp and 2 subs in the jeep tomorrow. I previously had them in my Cherokee with an aftermarket cd player. The wrangler has the stock cd player. I havnt had the dash apart yet but im tearing into it tomorrow. Should I need any type of patch cord? Does the stock cd player have RCA outlets on the back of the unit?

Any advice or input is appreciated

I am preparing to install a aftermarket head unit in my Jeep and currently working on the wiring harness.

Two areas of uncertainty with the wiring harness:
The adapter harness has 2 yellow and 2 black wires. The pioneer harness only has one of each. Is it ok to connect the 2 into the matching 1?

It appears the OP did in the pic he posted but I wanted to be sure.

Thanks

The wiring diagram showed them as the same thing. I wired the 2 constant power and 2 ground wires together and have had no problems. As long as your wiring diagram shows them as the same thing it should be fine to connect them.

Hey, you said you bought your stuff from crutchfield. Was the installation kit the one they gave for free when buying a radio? I'm looking to purchase my entire audio from them and wanted to know how well the installation kit looks and performs with the aftermarket stereo.

Yea, I bought the radio and the 2 pairs of speakers from them and all the plugs and adapters came free. It works great a year later.

Almost forgot I got the security cover for christmas last year.. of '09. The cheap lock broke off all on it's own just a few months later but I remove the faceplate most of the time and I think the lazy thieves will just find an easier target when they see it. I also like the little spot right below the radio. Perfect space for my charging phone.

Just installed an Alpine receiver (AM/FM, iPod, no CD). Console subwoofer works with radio but not with iPod. Any ideas what's wrong?:confused:

The reason for that is you have your sub amp turn on wire connected to the alpines remote power antenna wire instead of the remote amplifier turn on wire, one is blue, the other is blue with a white stripe, switch to the other wire and your sub should work with the ipod no problem.

UPDATES AND CHANGES!!
Bold and red to get your attention.


I've had a few PM's about the same issue so I'm going to post it here. Maybe I can get the mods to add this into the original post.

I have been getting questions on what to do with the 2 power wires and 2 ground wires that are on the jeep harness when they on have one for each on the stereo harness. I wired both jeep power wires to the one radio power wire, and both jeep ground wires to the one ground power wire. It has been working fine.

Another question asked is about having an amp installed and having it not on when playing cd's/mp3's/ipod. The simple switch of one wire is required. There is an antenna power wire and an amp power wire. Necromancer_tat answered this above, but for people who skimmed this thread may overlook it.
your sub amp turn on wire connected to the [radio] remote power antenna wire instead of the remote amplifier turn on wire, one is blue, the other is blue with a white stripe, switch to the other wire and your sub should work with the ipod no problem.
If the mods do read this and put it in the original post can you also add that the bolt behind the radio is either 10mm or 3/8" in size.

What is the wire connected to the bolt that goes through the security bracket into the stock stereo? If you bend the bracket out of the way, what did you do with the wire? Where did you connect your ground wire?

Thanks....great write up that keeps on helping !!!

Sorry about not getting back to you in time. But seems like you figured it out. A ground wire can really go anywhere there is bare metal, the thicker/more the better. You could use essentially any metal bolt that goes into metal, either wrap the wire around it or use a ring terminal.
