Installed Polk 650 Dxi in dash, Wow

I now have Polk 650 Dxi in the soundbar and dash. Wow, what a huge difference. I did Polyfil the speaker pods very tight. They came out too punchy, so I ported the Pod in 2 spots with a fairly large drill bit, one on top, and one on bottom, can someone say semi band-pass. That itself was a huge improvement, (I highly recommend this if you are getting too much punching bass and woofer seems to pop at you). I pointed the Polk tweet that is mounted in cone upward, and could immediately hear a lot more highs. I even went so far as to disconnect the factory dash tweeters, as they were ruining the sweet sound.

Needless to say, I am glad I did not get the infinity upgrade. I have 200 invested in 4 speakers, and I actually have a lot of bass now. Clean bass at that.

I did bring home the Polk 6500, which is there component set. After a lot of thinking with dash out, and tweets out. I couldn't make the tweeter sit in the factory spot, would have been way too much work. Aside from that, trying to figure out how to mount the crossover with very little wire, I gave up. I even thought about mounting to soundbar instead, and putting the tweeters in the angle that would face directly at your heads in front seat. After looking at the soundbar again, and mounting hardware, I headed back to return it. Needless to say, I am happy now.

Audio Done.
Suspension Done.

I had a buddy at Best Buy install my front componets and had him polyfill the speaker boxes. The way you explain the punchy bass is exactly what i am getting. Did you remove the polyfill completly and drill holes? or leave it in? How big was the bit? Very interested! Thanks!

Hey, ya it sounded really bad, lol. I packed too much poly fil and was not about to remove all that crap again. The drill bit was between the sizes of a penny and nickel. I put one on the angled part at top of pod, and one on the lower section. Both holes face the door part on Jeep, so you have an idea. I did leave the poly fil in, and pulled out very little from the holes a I drilled. Definitely took some punch out. Let me know if it works for you, I don't want to be responsible for bad results! LoL

I installed these same speakers two weeks ago. Mine are speaking from a JVC Nav head. I got a Polk Audio amp sitting under the driver's seat and the wire set laying on the work bench waiting for the time to run them.

They sound great but have you ever noticed any distortion/clipping at elevated levels when a deep base sound hits? It's my understanding that more power from the amp will take care of that plus kick those speakers into overdrive with sound quality. You don't plan to amp?

Yes, that is why I drilled holes and pulled some poly out of them. They were hitting way too hard. I could still see how very deep bass will distort them, but I blame the crappy pod they sit in. The speakers don't seal right against them due to warped plastic, etc...

Nope, sure don't plan on amps. I need my battery to not die if I leave radio playing at the beach all day, ha.

Hey that reminds me and sorry for this is off topic but,
When I leave my key on accessory for listening to the radio I hear relays cycling on and off about every few minutes. Does yours or anyone else hear this?

I think there was another post about this and the best example was a "ejecting CD" sound...I get it when just opening the passenger door without the key in and sounds like its behind the glove box

This is funny, when you remove your glove box, you can see this white roller looking thing rotating back and forth every few moments. Possibly some type of filter.

I highly recommend buying some xtc speaker baffles. I got mine from Amazon for $12 shipped. If you're happy with the sound now, you'll be blown away when you have a tight seal.

I just finished my system and I'm amazed. I have the Polk dxi 6500 components up front and db 650s in the soundbar. I'm powering them with the Alpine ktp-445u amp. The sound is just incredible.

So I just finished the Polk install, coax in sound bar and components up front. Basically the front woofers have some reverb/vibration when there is deep bass/loud volume. I used Dynamat in the sound bar and those sound pretty nice. Didn't Dynamat the front, kind of had to rush the front install and will see how to improve it. Inspecting the pods, the distortion doesn't seem to come from vibration in the pod, but from the speaker itself. I'm just wondering whether drilling the holes in the pod might be the cure for this or whether Dynamat and a bit more polyfill will cut back the vibration. Any insight?

My basic 130 radio distorts when the volume is 30 at 100 Hz -5dB. So maybe the volume level was too high? I installed an amp and don't need the volume level that high to be loud now.

Pulled out the speakers and installed some Dynamat and a polyfilled as well. Also noticed at higher volumes the horizontal frame the speaker sits on was vibrating and causing some of the distortion. So just placed a piece of Dynamat between the speaker and the bar to pad it a bit. All together, great install. Crutchfield directions weren't the best, mostly just "here's how to get to your speaker box. See manufacturer directions for anything else." Mounting frames need to be adapted as well. So a bit overpriced to just get simplistic directions from Crutchfield, but as far as the speakers go....love them. Great little upgrade and not too difficult in the end. Can't wait to locate an Alpine amp and give them a bit more power.

Today I installed Polk db651 speakers in the front and the sound bar. They sound awesome! I had to mod the mounting plate a little to get them to work. I was able to fit the factory covers back on the sound bar. Next step is to replace the stock HU!

When you say mod the mounting plate, what exactly did you do to it? I have mine on order and will do an install soon. By the way I got mine from Frys electronics for $49 + tax.
