Help choosing between two speakers

So obviously I can measure after work today, but how do I know if a 6.5 will fit up too? If I remember correctly, the 5.25 was fairly tight.

The 6.5"s are not a direct fit, very close but no cigar. I'll post a couple pictures late tonight of what it looks like. Looks clean IMO. My pods are currently in my basement waiting to be installed.
 
A guy on another forum put 6.5's in the dash but it required cutting of some of the bracketry and other mods to the dash. Too much work for not much return. A better bet would be to run separates so the tweeters are better positioned to the listener. That along with an amplifier with 75w/channel or more.

I am doing something like this. I am going fully active, connecting the tweeters to the A pillar and putting a 5.25" mid driver in the front dash. Then adding the two 6.5" wooofers to the speaker pods.

For the tweeters, got an idea to use a PCV cap, ball joint and steel nipple.
 
I always go and listen to speakers before I buy them now. Bought some speakers several years ago because the Spec's look good and hated the way they sounded. Go to a Best Buy or local car audio store and listen to different speakers. Even two models from from the same manufacturer can sound totally different.

And of course add a good size amp.
 
I’m referring to the roll bar... I have a 2004. Not sure if it accepts a 6.5

Here are some pics of a 6.5" Polk installed.

i dont have pic sof my 6.5 in my speaker pods but mine came out awesome. im not to thrilled with the 5.25 but maybe I need to tune some still then again i havent faded to the front to hear just the 5.25s
 
I’m looking to upgrade the speakers in my TJ. I’m deciding between Alpine Type Rs and Polk MM1s. I’m looking for solid sound with clear bass at higher volumes. I do not want to rattle the glass, I only want clear audio at higher volumes, topless on the highway sort of thing. I have upgraded speakers in there now, but when I have the volume on higher levels, the bass is distorted....even with the bass turned down low. The Polk’s have a higher sensitivity, but I’m thinking the Alpine’s will handle deeper tones better. Both are similar in price at $200 a pair.

Adding an amp is an option I’m considering,but adding a subwoofer is not. Thanks in advance for any input.

Hello tapatalk,
Im in the exact situation you are. I always like to listen to my faves on the radio but the speakers in my roll bar offend my ears so I never use the radio when driving my Jeep.I just want a good set of speakers. I don't blast but like good sound other than these tinny sounding things that are now here. I hope you find what you are looking for and would appreciate you telling me what you got. Im a 69 year old guy and love my classic rock, but won't listen to it thru shit speakers. Thanks brother and good luck finding what you're looking for.
 
Johnny -

The Alpine Rs are power hungry, and only sound good when fed power.

The Polks are a higher sensitivity, so they will be "louder" with the stock stereo / no amp.
I had the Polk DXI series... they were a bit too harsh for me- so I replaced them with the Alpine Rs... all four.

As for an amp and keeping the top down... me too... so I got one of the "brick" amps.... an MB Quart.... Pioneer makes them, Kenwood makes them... etc. and mounted it under the steering wheel, behind the knee panel. It fits fine, and is close to the head unit. I send out 80 watts x 4. Further the amp is marine rated amp anyway. (you are looking at under $150 delivered). It's an easy install...

My Rs have a fuller sound than the Polks. I also lined the soundbar inside and stuffed some polyfill. That will also help...
 
The more sensitive speaker will go you relatively more sound output as they are more efficient. An increase of 3db can give you a pronounced difference in sound pressure levels, so sensitivity is key. As far as sound quality, each speaker will list it's frequency response. The broader the response the more broad the sound spectrum. So if you're listening to Beethoven as you rock crawl, a broader frequency response will make all of the instrument sounds more defined.So i'd consider doing a comparison between both speakers that you are considering, and of course the relative cost. I am considering doing this myself so look forward to hearing about your results.
 
There are two ways you can achieve what you are after: read the post about enclosures. If cruchfield sells boxes for the front speakers get them. If you can seal the roll at speakers do so as well. Also use polyfill. More importantly, don’t use the base setting to reduce base but a small passive crossover to cut frequencies below 100HZ to the front and 80HZ to the rear speakers. Then you will save some midbass which coupled with the enclosures and the polyfill should cut the distortion.

I would prefer the polk as speakers for some reason. But it’s been a good while since I have listened to them. Will be upgrading mine soon, we will see.

Hope this helps!

So I ended up getting a pair of 6.5s for overhead. Obviously the mounting holes don’t line up, but I can’t mount all four screws in the plastic surround either. The diameter is just a little bit too small. Do I have to buy or make an adapting plate?

You have to get a bit creative. I had to use long screws and mount the cover and speaker at the same time. It worked but is kind of a pain. In hindsight I should have gone 5.25 because they really don't do much better anyway.

Did you get the Polk 652s? As you saw in my pics, what I did was attached the 6.5" speaker ring to the speaker pods holes, which lines up perfectly. Then I drilled new holes to attach the speaker cover.

I’ve had both the previous generation Polk mm series and db series in my boat. A boat has the same acoustic challenges as the Jeep (open and loud). I prefer the db series, better bass. I currently have the db 651 in my Jeep and Wetsounds xs650 in the boat. The Wetsounds produce a surprising level of bass from a 6.5” speaker because they float the tweeter over the woofer vs a traditional pole mount tweeter. Kicker marine also offers a similar design (had those in my old boat). The Wetsounds and kickers will require you to open the hole in the pod about 1/4”

Good Power will help too. I run a high power Sony indash unit that makes as much power as the little outboard brick amps. The Sony mex xb100bt delivers a true 40watts x 4. You can also power 4 speakers and a sub from the deck if they are all 4 ohm speakers.
 
I ended up getting a pair of JBLs (GX600C).

I tested quite a few out and I like these the best. They don’t hit like a woofer, but didn’t sound like they were suffocating at higher volume.

If the speaker ring's mounting holes are not lining up with the speaker pod's mounting holes then it could be that these JBLs holes are not in the same spot.

You can improvise if want, possibly add new holes or angle the screws into place.
