help with mounting polk DB5251 Tweeter Crossovers

My wife and I recently helped my oldest daughter get her first jeep. An 06 LJ Rubicon. One of the first things she wanted to do was upgrade the sound system. I did a bunch of research on here and the jeep forum and after a bunch of research I decided we should upgrade the speakers first. We started out with acquiring a set of Polk DB651's for the rear sound bar. stuffed the cavity with poly fill and got some speaker wire adapters and make quick work of that. We then purchased a set of Polk DB5251's for the front. I bought the select increments speaker pods for the 5 1/4's and installed them along with some additional speaker wire adapters. So far all easy installs with the aid of countless article on here and other places along with youtube. I ordered some of Nalin's tweeter mounts but had to wait to get in touch with him to determine the correct size. the specs on the Polk tweeters said the cut out was 2 1/16" yet Nalin's site didn't list it. I knew there was something strange since he also sold the Polk DB5251's on his site. After speaking with Andrew he advised me that Polk had incorrectly stated the cutout size and it should be 2". I have been wanting to mount the tweeters and crossovers and have not been able to find anything listed on where best to mount the crossovers on the driver and passenger side and was hoping someone on here may have already done this and may be able to help with some suggestions and or pictures.

I appreciate any responses with suggestions or pictures on where to mount the crossovers. The tweeter mounts should be easy looking at the Nalin brackets and the two bolts they attach to on the door bracket.

On another note, we started looking at head units/stereos and after doing some review and looking at some we decided on a kenwood KDC-x700 as my daughter wanted the ability to connect to her iPhone and play music. The place we physically looked at it said they could mount it on the spot for $60. I was planning on doing it but she said she was willing to pay and wanted it done. 30 minutes later were in business. she quickly wanted to connect her phone and play music. we switched to the radio and realized we had little to no reception. The place said aftermarkets have poor reception and said they location sucked and suggested we go on a ride. when we autoscanned for stations we could only pick up one station. We went back and they switched out the antenna adapter which only seemed to help a bit. We were both a little upset to say the least with the purchase. Now I am back to searching the internet for hours on poor radio reception with aftermarket radios and saw some post about troubleshooting the antenna or upgrading the antenna and possibly getting a booster. When I was about to give up and take the jeep back to have them look at it one more time I found an article on some jeeps having a split antenna cable behind the glove box and sometimes it comes lose when folks are either removing or installing a radio. I quickly pulled the glove box and was happy to see the antenna cable did have two metal connectors staring at me and they were disconnected. I connected them back and turned on the radio and to my amazement we now had good reception.

Once we get the tweeters and crossovers, we will eventually get the subwoofer upgraded and then eventually get an amp. I read some reviews about the amp mount to the steering column by skinny pedal products. After calling the various numbers listed on here I saw a post that they may be available at Cobalt trucks in Idaho. I got luck calling them as they said they have very few left.

All in all the stereo and sound is much better than the factory unit and speakers and we are enjoying some quality sound with the soft top driving down the road.
