I just put some 6.5 kicker comp vts in the sound bar in place of some 51/4 infinity references. Note: i did have to get out the dremel to make the holes just about 1/8 inch bigger all around. I put polyfill in my sound bar and bought a kicker 300/1 amp for 75 bucks on craiglist (a steal) and put in under my back seat powering both of my kickers in the sound bar! Just these speakers can now officially give me a headache (if i turn them up too loud). Still to add are some tweeters in the sound bar to compliment them. Up front I have infinity reference speakers powered by my head unit, they both have awesome crisp highs but not any mid bass, hence the new 6.5s. In the back I have an alpine 10 inch type r custom reconed with new dual voice coils to handle more power paired with a hifonics Brutus 1200d amp. If you put a setup similar to this in your jeep you will not need any kickpanels, and your jeep will become a more than worthy sound system at any farm party or tailgate.
(for a great budget head unit check out kenwood cde, got mine for 85 bucks and love it because I can plug in the iPhone via USB and control the music directly on it or push a button and let whoever else is riding with control the music directly on it all with my charging cord)
-- under the head unit is my 7 band equalizer for easier control over my whole system, had to modify dash to fit it in.
Forgot to mention to power all this I only needed to put in a sears diehard platinum battery, not a H.O. Alternator. (before the battery upgrade my electrical system took a beating, lights dimming etc)
And I know everyone on here is dying to know, and the answer is yes, you can fit a case in the trunk on top of the amp! I'm in the process of building this area into a plexiglass cooler with locking lid (so when I tailgate GO CHIEFS I don't even have to open the trunk)
I guess I had not thought of making the speaker opening larger in the sound bar. I guss I could also add tweaters there too. Might be a good place for a nice component set-up. 300W is way too much for me. Was just going to get something in the 60 to 100W range.
My front speakers are infinity reference model 6422cfp 4x6s. To get them to fit to the jeeps strange sized front speakers I used a saw and cut the stock speakers out and used the surrounding material left as a bracket. But I would highly suggest looking around for jeep front speaker brackets for a 5 1/4 speaker, (about $11) they are more powerful and balanced with the rest of the system and i plan on switching mine out pretty soon. In that scenario you could take the speakers out of your soundbar and use them in the front, put some good 6.5s in your sound bar (not every 6.5 in speaker will require you to make the hole bigger) and I would certainly recommend that you get an amp. For aftermarket speakers in cars these day even aftermarket head units are not enough power. They put out generally at best 22 watts rms to each speaker. The 300 watts rms that my Kicker amp outputs is really not that much, and is divided into each speaker at 150 which can make them load but really gives them a chance to have some responsive punch and 300 watts will not drain your electrical system at all if wired correctly. It is important to know what the rms watts rating are on the speakers you buy and match with an amplifier or amplifiers that are rated with the same or close to the same output power AT THE SAME OHMs of the speakers. If you don't know about wiring speakers and plan to do it yourself do yourself a favor and find someone to talk to who does so you buy the right things and dont literally blow your money away. My kicker 6.5s are also classified as small subwoofers (they are not) which means they should have a larger magnet, sturdier cone, and more power handling capabilities to reproduce better high-mids to mid-lows. Don't add more speakers, do yourself a favor and spend the money to get ones that can handle some power, then amplify them. If you want to keep the kickers 5 1/4s in your sound bar find another of the same set, put them in your front with the brackets and buy a 4 channel amp to power all of them. The question is now what kind of a system do you want to build. I personally am extremely happy with mine, am going to put in a two channel amp for my front components under the back seat eventually. (3 amps is only too many if they take up too much space)
Amping your current aftermarket speakers will definitely be the way to go since you already have all that in place.
I went with the q-logic kickpanels with a component set in them and an amp and it sounds pretty awesome! Really surprised at how much imaging and staging I was able to get in a Jeep, though, I wouldn't recommend them to everyone. Since you already have the aftermarkets in place, just amp them and you'll notice a huge improvement as long as you match up ohm loads and power ratings as well as set gains and EQ properly.
One more thing, 6x9 speakers are crap and do not last. The 6.5 kickers I have sound better than any 6x9 I've heard and fit in the sound bar. (and I used to have 6x9s in back)
Can you get a 5 1/4 to fit in the dash? If so, what needs to be done?
Also, how exactly did you get 6.5's to fit in the sound bar?
I like the idea of tossing the 4" I have up front and repalcing with my 5 1/4's. Then, upgrade the sound bar speakers with something that can handle a amp. If that si not enough, then I will just add a 2 channle amp for the sound bar.
To make them fit you will need to use a dremel or another thin metal cutting tool with a cutting disc, and cut about 3/8" bigger all the way around on each speaker hole in the sound bar for a total of a 3/4" bigger hole. You will also need to use a drill to drill new holes for the mounting screws. It really isn't that bad to wire them either get the 4ohm version and wire the pos and neg from one through the sound bar to the pos and neg of the other. Then from that same speaker run another wire to the pos neg on the amp. (just drill a small hole in the soundbar and run the speaker out the side) This will give you a 2ohm load and give the speakers the perfect amount of power. Also go to Walmart and get some polyfill in te crafts section to stuff in your sound bar when youre done cutting, really improves the sound depth.
Here is what I decided to do. I found a bracket on ebay so i could move the 5.25's to the front. That sould help some. My Crutchfield rep talked me out of 6.5's and instead, I went with a KS series Kickers (5.25) for the sound bar. The reason is because of my powered sub and he thought the mid and highs would be better with the smaller diameter speaker. Once I get them all moved around, I see how it goes and then devide on an amp.
