5.25 or 6.5 speakers? HELP!
 
So I am thinking about updating my sound system in my 2003 Wrangler. I am biased towards polk audio so whatever speakers I decide will probably be by them. Anyways, I heard that 6.5 speakers fit in the roll bar but is this hard to do? If its a pain then maybe its not worth it, but if its something simple then I would like to do it cuz from what I have heard 6.5 sound way better then 5.25 speakers.

Here are links to the two different sets of speakers.

5.25 --
Polk Audio db5251 5-1/4" component speaker system at Crutchfield.com

6.5--
Polk Audio db6501 6-1/2" component speaker system also fit 6-3/4" openings at Crutchfield.com

Anyone with experience or advice is much appreciated! thanks from a fellow jeeper! Dont forget to wave

Don't know about the Polk's, but with my Kicker 6.5's I only had to make new mounting holes. I'd say it's worth it, then you can upgrade the dash speakers to 5.25's.

jeepwayoflife 06-08-2013 11:32 AM

Yes the Polk DB651's will fit in the sound bar after you drill new screw holes. As suggested above, get the mounting plates and put 5.25" speakers in the front dash. That will be a huge improvement over the 4x6" cardboard speakers

Jerry Bransford 06-08-2013 11:42 AM

It's hard to beat those Polks, that's what I would go with too. Polk's DB series of speakers have a high >90 dB Sensitivity rating which means they sound good without requiring a lot of power to drive them. That's what you need if you don't have an aux amplifier.

I got a pair of 5.25 Polks at Bestbuy for around $80 a couple years ago. They sound great with the stock stereo.

JRoweMDN 06-08-2013 01:56 PM

I just added 5.25 components to the dash with Nalin adapters. I have 5.25 in the sound bar and I am pushing them with the RF 4x75 amp. They sound really good. The 6.5 did not seem like an easy change. They did not line up and cover the hole very well so I kept the 5.25. Since there is no real bottom end I modified the console and added an 8" polk sub with another RF 300x1 amp. With the addition of the sub I have great all around sound. Without the sub it is a little too bright.

lildrummaboy16 06-08-2013 10:11 PM

So you had the polk 6.5 speakers in your roll bar but then realized they didn't fit well? I have read a couple reviews where guys have gotten them to fit but they just had to re drill a few holes and that the stock speaker cover wouldn't fit anymore. But if that's true it's doesnt really bother me cuz polk gives you a speaker cover anyway.

lildrummaboy16 06-08-2013 10:11 PM

By the way Thanks for all the insight guys! Super helpful stuff keep it coming!

JRoweMDN 06-12-2013 09:34 PM

No I never installed the 6.5's because they did not line up very well. I may still go back and try them. I am pretty happy with the sound I have now but it definitely needs the sub to fill in. I am still playing with the settings to get the best sound.

eboven 06-13-2013 12:00 PM

If you have the factory full length soundbar (97-02), 6.5" speakers will fit just fine; just drill new mounting holes and use the grille's that the new speakers come with. If you have the factory sound pods on either end (03-06), they won't fit quite as nicely, but should still work without too much trouble.

The big upgrade in sound will come from upgrading the fronts from a 4x6 to a 5.25 with the Nalin MFG brackets. I went with the component plate set with separate tweeters in my TJ and couldn't be happier with the sound difference. Check out my TJ Audio build thread for some more ideas and information.

n00g7 06-13-2013 12:17 PM

Waste of money without an amplifier, and excessive with. The pods can't even handle a 5 1/4 speaker, let alone a 6 1/2. If you do a component set, I wouldn't bother with the tweeters in the back.
I have 4 of these Amazon.com: Infinity 529I 165W (Peak) 5-1/4 -Inch Two-Way Speakers (Pair): Car Electronics paired with a sub, which are more than loud enough to get a ticket.

I completely disagree, especially since the size of the speaker has little to no bearing on how much power it requires to be properly driven so it sounds good. Some 5.25" speakers require more power to be driven properly than some 6.5" speakers do. With even the stock head unit, going with a better speaker like Polk's DB6521 will produce noticeably better sound. VERY noticeably better. I did that for my previous TJ & was very pleased with the results. Looking at the speaker's Sensitivity rating as I described above will help to select a speaker that will work well for the stock head unit's relatively low power output.

And I have more than a few years involved in building and selecting audio gear. I built my first high-quality stereo amplifier from scratch in the 60's and also built my own high-end acoustic suspension speakers and wired my own crossover circuits starting back then too.

So while yes, you can make a better sounding stereo for a Wrangler with a more powerful aux amplifier & speakers capable of handling that higher power, that isn't to say you can't get dramatically better sound by simply installing better quality speakers. Such as the above mentioned Polk DB6521 that don't require more power to be properly driven than the stock head unit can provide.

I used Pioneer 6.5's in my overhead bar and didn't have to change a thing. The factory bolt holes lined up perfectly.

Sure, but I was referring to the fact that putting any bass whatsoever to the pods sounds like crap. I have the HPF set pretty high for mids and highs only.

However, $400 worth of Tier 1 speakers is unnecessary to run without an amplifier, let alone an OEM head unit. The speakers I noted are very good mid-range speakers, which have a 94dB sensitivity rating, from a highly reputable brand. The difference between $400 of polk and $160 of those infinity's on a stock HU and no amplification, none. Even with amplification, the crappiness of what we've been provided for acoustics in the jeep negates any appreciable advantage of the polks.

I know you know a lot, but it doesn't mean the rest of are dunces, or my recommendation that OP save $240 in scratch on speakers that make just as much sense in a jeep isn't an equally good route. And as an electrical engineer, I've derived plenty of transfer functions in my day for those and other circuits such as power converters.

We have pods.

The Polk DB651 6.5" speakers I recommended can easily be found for $65/pair in many retail outlets. So I sure don't know where you came up with your $400 for the recommended Polk speakers. And let's not lose sight of the fact the OP doesn't want anything but simple replacement speakers and simply asked if Polk speakers would be a good choice.

JRoweMDN 06-13-2013 03:01 PM

I will say that a stock "22w" head unit does not push enough power through the polks to hear at highway speeds with no top. Maybe I like my music louder than some but It needs the amp to be clear at higher volumes too. They are good for town but they really need a small amp. The Fosgate PBR 300x4 can be had for around $150. With all the fuses and wiring needed to install it and 4 new Polks should still be less than $350 and will be worlds better and for the $175 it is money well spent. I also highly recommend putting some polyfill in the soundbars and buying some $6 Boom Mats for the fronts, the sound difference was definitely worth the effort and small cost.

If anyone has some photos of the installation of the 6.5's in a 05 sound bar and how you lined them up I would like to see them. I just did not feel like there was enough bite to put the screws in the lip around the stock openings.

Sorry Jerry, I didn't catch that you were talking about the DB651 -- OP posted up the DB6501 and DB5201, which are near $200.

I bought the polks (DB521/DB651) initially but switched to the 529i/629i infinities for the +/- 3dB setting, but it's really a wash.

BurlySoldier 06-13-2013 04:30 PM

Swapping in 6.5's is a piece of cake and well worth it. Epsecially a nice brand like Polk. Do that and the 5.25's in the dash- Good to go!

I installed car audio professionally for over 7 years, and installed countless Infinity and Polk speaker setups; there is virtually no difference between the two brands. Polk advertises that their speakers are marine rated, while Infinity seems to push their lower nominal impedance and high sensitivity. Really, after installing them for so long, it seemed to me that they were made in the same factory and then just slapped the brand name on there; same baskets, motor, cone design... slightly different sound, but to the average listener it was hard to pick that difference out.

The bottom line is what the OP really wants - if you only want to swap speakers and do nothing else, go with the Polk's or Infinity's... it really does't matter which you choose. They both will sound the louder than many other speakers out there when running them on the limited power a headunit will provide. You will be able to hear your music more clearly and it will probably sound a bit louder, but as someone already said, if your top is off and you're cruising at 60MPH, it probably won't be keeping up.

If you decide to go with an external amp, there are tons of better choices for speakers than Polk or Infinity. If you are actually providing the speaker the power it wants (RMS watts) you will really see a difference in sound. I run a 5-channel amp mounted under my dash so it doesn't take up any precious space. It provides close to 50 watts RMS to each dash and soundbar speaker (over double what any headunit alone would provide) and allows my speakers to stay clear at louder volumes. I have no issue hearing my radio at any speed, even when topless/doorless.

Gixxer86g 06-13-2013 05:44 PM

Like many have already said, the Polks are great.

But you can really get a sweet system for a fairly low amount of cash.

I went with the Polk dbs. 5.25 in the dash, 6.5 in the soundbar. The dash speakers have baffles. The soundbar is stuffed with poly.

I use a Sony amp that provides 50w RMS to all four speakers. I run a Sound Ordnance B-8pt under the rear seat.

None of this stuff was expensive, and I'm quite satisfied with the sound.

NalinMFG 06-13-2013 05:52 PM

+1 for Polk. :thumb:

JRoweMDN 06-17-2013 09:17 PM

+1 for the Nalin mounts. The stuff is well made and makes install a breeze.

Rendell 06-18-2013 02:25 PM

Not sure why no one in this thread answered your question directly. If you have pods on the roll bar like I do (2006) then 6.5" don't mount right up. I think they did in older sound bars.

I have alpine 5.25"s in my pods, and I ran the factory grills until they started to come apart. So then I got the Alpine grills, and had to dremel them down on the outside a bit to make them fit in the recessed lip.

That said, I have the fade turned almost all the way to the front where I have the same set of Alpine's in an adapter bracket.

I have the pods also and my 6.5's mounted in with no problems, just made new mounting holes.

03, pods, with 6.5

The best thing I ever did for my tj stereo was build a custom bar for massive audio rk 6 components and 2 massive audio m8b and put a alpine mrx-65 on it but now 2 10" subs won't keep up with the mids and highs so I'm working in a custom sub box would give picture but can't figure out how

ChasUGC 08-05-2013 08:33 PM

I wouldn't combine 5.25 and 6.5 for the best sound. I would use 5.25 all around by the same manufacturer. Also, Polks are 45wattsRMS, Infinity 55watts RMS. If you run an amp through any of those speakers, they will blow. I blew my Infinity's and they are rated higher than the Polks.

BruteOutdoors 08-05-2013 09:36 PM

I bought the slim Polk 6.5" speakers and have been extremely impressed with them. Didn't even have to drill new speaker holes. They screwed right in with no issues whatsoever. They sound significantly better than the 5.25 components I have up front so I'd highly recommend them. It took about 5 minutes and sounds great.

Mixing sizes is not going to affect sound quality.
