Ephry73 With the PAC I have CHR3 and the 445u I think my needs are covered. I even bought a Hideaway Kicker setup to put under the passenger seat. I can always unplug it if I take the doors off or go mudding.

tlminh does the amp get hot while sitting in the glove box? I put all my important documents/tire pressure gauge/sway bar disconnects in sandwich baggies that go into the glove box. Dont want to start a fire hazard

Ephry73 Thanks for the reply. I do not have the premium, just the base 130n with Uconnect. I purchased the PAC and it basically connects to stock radio and wiring while giving me front and rear RCA outputs. This is what I will use to connect the Alpine Amp.

You will splice... no PAC will help unless you only have the base stereo and not the premium. If you have the premium, you will have to splice into the wires leaving the amp (not the radio) and heading to the speakers.

I found this on the 'bay and wanted to know if anyone has tried this, or something similar to tie the system together.
I have the version of this amp that plugs and plays with an alpine HU. Love it. Provides just enough of a boost. Sits on the shelf just below the glove box.

7ekken I actually installed one of these on a customer's vehicle a few days ago and I can tell you it is a quality amplifier.

It can be used as a high level (or speaker level input), or a low level input (RCA). I don't recommend using a factory radio with the amplifier but it IS able to be done and mounted directly behind the factory radio. I do recommend running a 12 or 14ga constant wire for this amplifier as it can draw up to 15amps of current. I wouldn't recommend wiring this into the factory radio harness 12v wire as it could overload that circuit and blow a fuse.

If you install this amplifier please do yourself a favor and read the huge poster sized pamphlet it comes with about tuning this thing. The proper way and the way they want you to do it is to turn the gain all the way down on the amplifier. Then turn up the volume on the radio being used to the point it starts to distort and then back it off a little so it is clear. After that is done, then turn up the gain on this new amplifier to the point of distortion and then back it off a bit.

The customer I installed this for was in an 05 Civic with Polk DXi 6.5" speakers... so I cannot speak for how it sounds in a Jeep. The sound quality and volume was very good. I am recommending this module to all of my customers if they are looking for an inexpensive way to upgrade their sound.

igf101 From my understanding, this amp is designed to plug and play with factory HUs. I did read about the complications with the factory HU limiting the soundbar...even with the frequency cutoffs, I'm wondering if the boosted power would at least make the speakers serviceable.

3TimeOwner ummm depends on what you are trying to do. You can't just plug the amp in and off you go.

have a look a these threads, there will be other parts necessary

Alpine KTP-445U

Has anyone bought Alpine's new KTP-445u amp? I bought my 2012 JK two Fridays ago, and I'm looking to upgrade the sound system (Sport S, base sound system), but I really want to keep the factory HU. I'm also looking at the Polk DXi 650s and 6500 for the soundbar and front.

With the KTP-445u, keeping the factory HU seems like a doable option. Thoughts?
