Audio build for beginner: Advice needed

Hi guys,
The time has come for my 2011 Jeep’s audio system to be upgraded. To put it mildly I am not quite knowledgeable about this stuff so I would really appreciate your comments here.
The proposed set up is as follows:
Front doors: Hertz HSK 165
Back doors: Focal IC 165
Amp: Alpine PDX-v9
Sub; JL Stealthbox or custom made enclosure with one of slim line Phoenix Gold subs (I have not decided which way to go yet.
I do not have any experience in this field so the installation works will be done for me. The guys I contacted with this request suggested installing PAC SOEM-4 4-Channel Premium Line-Out Converter. I am not quite sure if it is really needed as I have not seen that anybody mentioned this thing here. On the other hand the installers are one of the best in town and obviously know their trade. I also read a ton of woeful reviews for this converter with complaints about adding noise etc. So, I am a bit lost here if it is really needed and if yes what should be used instead of this particular model.

The guys also suggested doing doors deadening which I guess should improve sound quality. Could anybody please tell if the results of the deadening are really worth it?

Finally, I am wondering if anybody ever dealt with Phoenix subs. I understand that they are inferior to JL. However, it may be possible that in custom made enclosure it will be possible to go with 12” slimline sub which may bring sound to a better level. Just a thought…

Could please anybody help me with this questions? It looks like the project is going to blow a hole in our budget of almost $4K so I do not have room for mistakes.

PS I have Laredo with basic 6 speakers (no sub or Alpine gear) and factory 430 unit which I am going to keep.

My set up is very similar to yours; I have Hertz Hi Energy comps in the front running active with 75 rms watts each, Hertz Energy coax in the back, Hertz Energy coax in the dash, JL Stealthbox, JL and Alpine amps and the Rockford Fosgate 3Sixty.3.

In general I am very happy with my setup; however its been a month and half already since my install and I am still working on tuning the system.

You have top-notch parts in your vehicle. My suggestion for you, before changing components, is to find a good tuner that helps you in setting up your audition dap right. I think that is the key for you. A good tuner will many times use an RTA to ensure accurate calibration and eq tuning.

Just my 2 cents.
