If you have a soft top it won't sound as good as a car with less. I have a Kennwood deck and Polk audio speakers. My power out put is about the same as yours. I have the same speaker configuration as you want. That is why I bought my sub console for just a little out of sight bass. But now I have to figure out where to put my amp at.

With 5.25" and 6.5" you should have pretty good sound. The stock sub is a 6.5", though that size is crappy for a subwoofer more like a regular woofer. You need to get speakers that support more wattage than the output of the head unit, and make sure you look at RMS wattage and not peak. I would go with speakers with 50watt RMS, that way you could turn it up all the way and you would kill your head unit before the speakers. You would be hard pressed to find a 6.5" speaker that had a RMS of 25w that cost more that $10 bucks. If you want good sound, get good speakers(you get what you paid for). If they are quality speakers they will be able to take anything your radio can put out. Also you will want to get baffles for the speakers because in a wrangler there is nothing blocking the sound coming from the back of the speakers. Crutchfield sells them pretty cheap, or you could just get some cotton padding and stuff your sound bar and dash with that stuff like I did.

Hope that helps.

This unit has sw input already, i just do not want to waste any space as there is not much in these Wranglers. What amp? Didn't you say you have similar stereo unit? If it is, you won't need an amp right?

Sorry for my ignorance if I get you wrong.

I will help when i fully understand you

so for soundbar speakers I am looking to get 6.5 inch ones, what is the max power I can get those? 50watts each max?

Also just bought 5.25 kickers (70watts I think), should I move them to the console, or should I dump them and get something else?

Sorry for my sound ignorance.
And thank you all for your time, keep them coming

Yes I do have a similar speaker set up. The amp would be for the sub in my console that I don't have in yet. My Jeep is a 97' SE it didn't come with a sub console or a soundbar. I put them in. Sorry for the confusion.

I wasn't mentioning putting in a sub, I was just stating that using 6.5" speakers would sound better than having the stock subwoofer. You shouldn't need an amp, looks like a good unit and adding an amp is a hassle. You would need to route wires and find a place for your amp.

You have to do a little modding to put 6 1/2" in your soundbar. But not much. Are you sure you are going to put a set of 5 1/4" in your console? And not in your dash.

Someone told me to hook up the speaker with 1 screw first, and mark the other future holes and drill... Sounds like a no hassle mod to me. Am I wrong?

Also 5 1/4s will go to where 4x6s are, is it console or dash? That's what I meant

THanks

If you're wanting to drive the speakers off of just the head unit, one important thing to look at is the speaker's sensitivity. This is a measure of how much sound the speaker is able to produce with the amount of power. You're not going to get top quality sound out of just the head unit, so you just want to try to get good volume w/ out having to crank the receiver to it's highest output and cause distortion.

Ok... That sounds intelligent. So according to specs above, what type of speakers do you recommend? That's exactly what I want. Speakers that can handle the power of the head unit.

Thanks

The best thing for you to do would get a copy of a Crutchfield catalog, or go to their site, and look for what's in your budget, and then get the best quality speaker w/ the highest sensitivity within your budget.

I believe I only need 6.5 inches for the soundbar. My question is: what power is recommended max for speakers If I put the 70watt 5.25 speakers in dash.

Thank you

Here is the confusing part for me: in the link below, it shows what the power limit of those speakers example:
5-60 watts RMS power range (260 watts peak)
2-60 watts RMS power range
2-50 watts RMS power range
6-50 watts RMS power range
2-80 watts RMS power range

http://www.crutchfield.com/g_52000/6...ers.html?tp=95


I want to get speakers that can handle the head unit, nothing more nothing less.
Thank you guys

This will answer all your questions.

Go to this website. It will teach you everything you care to know about car audio. I have an electrical engineering background and everything on this website is accurate and checks out.

Car Audio Book - Free Car Audio Information

Now, for adding a subwoofer that is better then the stock that doesn't take up much space.

Check out a Boss Bass600 or Boss Bass1200

These are 8 and 10 inch subs respectively and they are enclosed in a box with a built in amplifier that puts out 100 watts and 165 watts RMS.(The subwoofer itself is rated much higher which is where they get their RMS and peak values from, but ignore that) These amplified subwoofer enclosers are extremely thin! The Bass600 will fit underneath your front seat and I currently have one being shipped to me and will attempt to fit in into the center counsel(I may have to cut a corner off the box if it is possible...) I will let you know how that goes and post a picture.

I have also seen these subs mounted flat against the tailgate and also under the rear seat as well.


Also, make sure that the Ohm rating on the speaker isn't too low(the lower the number, the bigger the load on the head unit will be). If you try and connect a 2 ohm load to your factor head unit you will burn up your head unit and even risk starting a fire in your front dash!!

Also note that the factory sub will NOT work with an aftermarket stereo, that is why I am picking up a Bass600 from Boss Audio and trying to mount it inside of that counsel. It's going to be a very tight fit and I will let you all know how it goes in about a week here. If it doesn't fit then I am putting it underneath my seat.

Islandmonkey,

This is going to be the easiest thing for you to do:

Call Crutchfield directly: 1-888-955-6000
Talk with an Adviser, and tell him exactly what you want to do.
I'm sure he will be familiar with your HU, just let him know it's a couple years old.
He will then be able to match up the type of speakers that you will need for your HU.
Crutchfield Adviser's know there stuff when it comes to specs.
However, I don't think there very in tune with putting 6.5" in the soundbar and 5.25" in the dash, so they might question that.
Don't worry about it, it makes NO difference.
Just tell them you need a set of 6.5" and a set of 5.25" to be matched up correctly with your HU.

As I said before:
If you run a soft top or are topless alot, you might need an amp to be able to crank the volume and clean up your sound.
A 300watt 4-channel should work just fine.
Ask the Adviser about this.

Baffles:
Imo, they are useless in a Jeep.
#1. You would NEVER use a baffle in a soundbar.
#2. Using a baffle in the dash just deadens the sound, and doesn't allow your speaker to sound full. I've tried it. It makes the speaker sound flat and dead.
But try them if you want.
Crutchfield will let you return them.

When your ready to purchase your speakers:
Here is a code that will give you $20 off your purchase: p2fsx-a8dv1-ij5c0
Just give it to the Adviser when you're getting ready to pay,
or enter it in the provided box if you're buying online.

Man...I thought I was deaf...but I run topless every nice day I get and I have absolutely no problems hearing my stock speakers with my Pioneer headunit. And even my sub has a nice little thump to it.

Normally I hate stock setups...my last vehicle had components in the doors (6 1/2" mids with coax mounted tweeters) and two 10" subs and sounded pretty slick...so for me to like the stock Jeep speakers is surprising.

Now of course, if you speakers are shot...or you have a crappy headunit, by all means...replace your speakers. I'm definitely not against it. Just making an observation that apparently most of you all are apparently more deaf than I am (and I'm pretty deaf...lol).
