TJ - Front Speaker Improvements ?

Hello.

I have some 5.25" speakers in the front of my TJ. But they don't sound very good. The same speakers in a friends car sound way better. He said that's because of my open speakers and a missing baffle.

How could I improve the speakers?
Does a small box fit there behind the speakers?
Any other idea?

Thanks for your help!
Nicolas-Eric

I'm still saying the Q-forms kickpanel enclosures are going to be your best bet at getting good sound with imaging and staging in the Jeep!!

Outside of that, you could try some of those plastic/foam speaker cups.. I think you can get them from crutchfield or some other online source..


And your friend is right. The dash speaker locations suck cause it's basically a free-air speaker. No enclosure around/behind it.

I recently did a stereo install with polk 5.25 speakers in the dash and sound bar. speakers sounded ok but ones in soundbar sounded quite a bit better than the dash speakers. I ordered a set a of foam Metra speaker baffles from ebay and am very pleased how much better the dash speakers sound now. Baffles were only about $12 bucks delivered.

Get the baffles its about the only way. Amazon sells them for like $5 plus shipping so that $12 sounds about right. If you have a large piece of foam you could make your own, like old seat cushions or something like that. All you really need to do is separate the rear of the speaker from the front of the speaker and the sound will improve greatly. Dont forget to put some poly-fill in that sound bar too. much better sound!

Fill the Voids behind the Speakers with PolyFil for a NOTICABLE improvement of
night & day.

That's what I was talking about! Will make a noticeable improvement!

Like LilYeller said, it's all about separating the rear of the cone from the front of the cone.. Will minimize cancellation and improve low frequency response..

the baffles work good when used for the front speakers, almost makes it a sealed enclosure for better sound and they are cheep

Ok thanks!

Now I only have to find these baffles here in Germany.
Or will polyfill do the same?

poly fill wont work in the front. there is nothing to hold it in place. if you cant get amazon to send you the baffles then I would go the foam route.

Can't I use some tape for the polyfill?

What kind of foam so I need?
Shipping the baffles to Germany costs 45$...

You can use any type of foam from an old seat cushion out of a vehicle or old sofa anything like that would work. just scoop out the foam enough to let the speaker sit in there and cut it to fit. thats the best way I can describe. I might be making some for my TJ this weekend so I can post up some pics if you need more info.

Post up the pictures. I just ordered some 6.5 Infinity references for the soundbar and 5.25 references for the front too. I need to order that bracket for the 5.25's now. Where can I get this bracket?
Thanks

Not sure if seat foam is the best idea. If the speaker gets hot it could melt the foam or cause a small fire. Polyfill is made not to burn under high heat

I dont think your speaker wont get hot enough to burn foam. not to mention that the foam will not even be close to anything that would get hot tnough to melt it. All you are doing is building a "box" out of the foam the only thing touching the foam will be the speakers magnet and the cage around the back. Tho I can appreciate your concern

Poyfil works just fine in the front and it doesn't fall out. Cost 3$ for a bag at Hobby Lobby.

Not trying to hijack the thread, but here's a question someone on here may know; my Jeep came with the seven speaker stereo system. The dash speakers are actually a 4" mounted in a ~ 4"x6" plastic shell and a tweeter mounted on the exterior of the plastic shell. It appears that a 4"x6" speaker would go in the plastic shell if the 4" round hole was elongated to 4"x6". The plastic shell would act as an enclosure for the 4x6 speaker. I would use a two way or three way speaker so I wouldn't lose my tweeters. Has anyone ever tried to use the plastic enclosures for a larger speaker than the stock 4"?

Go on eBay and order speaker brackets for ur TJ. It's 7 bucks a pair and they work awesome. It turns ur 4x6 into a 5.25 which have more speaker options and are just a better all around speaker. Just did mine and they sound amazing.

Sounds like a nice set up, let me know how they work out, I've heard lots of good things about Infinity speakers. BTW, how are you fitting the 6.5 Infinitys in the sound bar?

Sounds like 5.25 with polyfill is the best option for the dash. Anyone have any other speaker brands they recommend? Still trying to decide how I want to upgrade the sound system in my 06 TJ

I have all infinity components. The 4x6 6412 CFp. Reference. And the 5 1/4. Component 5010 Reference. The 4x6 are in the stock dash And the 5 1/4 are in the sound bar. all have the custom baffles for them . And the 1.5 inch tweeters are in the corner of the roll bar padding of the inside rear. Also I run a pioneer 12 with a 300 x 1 phoenix gold amp. All of it is ran by a pioneer head unit

The most popular speakers in my experience have been Polk DB521's. Also take into consideration that they are marine rated in case your Jeep gets wet.

Awesome thanks! For anyone else interested, I found them on the cheap at amazon: (About $50 less than Crutchfield)

Thanks !!

I used polyfill behind the front speakers and they sound so much better now.


I also installed a new amplilfier with 150W RMS for each speaker and that sounds also much better and louder than the old amp with only 70W RMS.

Btw the speakers have only 70W RMS / 120W Max but they can handle the 150W without any problem.



My actual setup:

2x 5.25" Audio System M 165 Plus speakers in the front 120 Hz - 20 kHz
1X 8" Audio System HX8SQ kickbass speaker in the center console in a MDF housing - 60 Hz-120 Hz
1x 10" Audio System HX10SQ in a ported MDF box - 20-60 Hz.

1x Impulse SD-700 amp with 2x 155W RMS for the front speakers and 1x 250W RMS for the kickbass.
1x Impulse SD-500 amp with 1x 585W RMS for the subwoofer.


My dad said that sounds wy better than the 8.000 Euro sound system in his Mercedes S500.

And its that loud... When Im inside the Jeep more than 50-60% begins to hurt...




BTW. I disconnected the rear speakers. With speakers only in the front the sound is more clear and better.

if your considering the foam speaker baffles use poly fill as well, i made a a test to see how they sound and now im needing poly fill too,
video i made in foam baffles -
and a thread to help me justify using both - http://www.jeepforum.com/forum/f20/s...33/%20https://

also i might be resurrecting this thread but im sure it gets read enough being one of the first threads on google.
