I am starting this post to help others trying who are trying to upgrade their factory 10 speaker Alpine RER system, but keep the factory deck.

After doing TONS of research on this horrible sounding (in my opinion) stereo system. I decided to upgrade.

I had originally tried to add just a Bazooka BTA8100 tube via the high level inputs taken from the sub (it sounded like crap) I then upgraded the speakers (Boston pro50SE's in the front and Focal 690CV's in the rear) That mod actually made a huge difference in sound. If you only wanted to upgrade your dash/door speakers and didn't really care about bass, some nice 6x9s and 3.5s it would be well worth it.

For me though...this was not enough. It still lacked bass and I couldn't use the tweeters in my component speakers unless I wanted to put them in the dash where the 3.5" speakers were. Ive read that several people have tried that and it sounded crappy and echoed off the windshield. TIME TO UPGRADE AGAIN!

Ordered a Peripheral PCH8 summing/line output converter and an Alpine PDX-5 amplifier. **I had originally planned on using the PDX's 5th channel (300w) to run two 12" subs in a custom box, but after hearing how the factory sub sounded with some nuts behind it and the 8" Bazooka, I felt it was more than enough bass (plus it doesn't really take up any space and I get to keep the floor storage compartments.)
If i had to do it over again I probably would have bought an Alpine PDX-4.150 and ran two sets of Boston Acoustics components Pro60SE's for the rear and Pro50SE's for the front in conjunction with a Bazooka BTA8250D**

Already had these installed.

3. Boston Acoustics Pro50SE 5.25" Component speakers. (front)
4. Focal 690 CV 6x9 speakers (rear)
5. Bazooka BTA8100 amplified bass tube.

I work at a salvage yard and we had a 2009 Ram crew 1500 with the Alpine RER system that came in wrecked in the front. I was lucky enough to be able to dissect and check the polarities on ALL the speakers/amp so I didn't have to tear my truck apart.

Mounting the speakers in the rear doors, I needed 1/2" spacers for the 6x9s and in the front doors mounted the 1" tweeters in the upper door trim panel triangle in the front doors.

I left the headliner speakers and the center dash speaker stock. Took the LH and RH dash speaker leads, all four door speakers leads and sub leads (coming OUT of the factory amp) and ran them into the PCH8.

High level (speaker wires) input of the PCH8:
channel 1 was the rear door speakers (which were the closest to full range frequencies that I could tell)
channel 2 was the front door speakers (low to mid frequencies only)
channel 3 was the dash LH and RH (high frequencies)
channel 4 was the subs LH and RH (low frequencies)

Low level (RCA's) output of the PCH8:
channel 1 went to the PDX5 front high pass
channel 2 went to the bazooka low level inputs.
channel 3 went to the PDX5 rear high pass
channel 4 went to the PDX5 sub channel (I used this channel for the factory sub because the PCH8 has a remote level control on it which is nice for controlling the bass, and the Bazooka already had its own remote level control)

Just for now I left the summing levels at 50% gain until I can get someone to help me professionally tune it in.

Let me just tell you, it sounds incredible! Even better than I had hoped for. :)

I hope this helps anyone out there looking to do this. I will post the wiring colors/polarities and photos if anyone is interested.

There are 2 plugs that come out of the "alpine" amp (even though it says Chrysler right on it) One is a 22 pin white plug and the other is a 16 pin black plug.

Great write up and looks like a very clean install from the pics. :rep:
 
#4 · (Edited)
can you post pic of the 8 inch tube. I want to see where you put it. Does it fit in a quad? Also so you actually ran 6 speaker wire from under the drive side to the amp? Where did you hook up the dash speaker wire to and what is powering it? from what i know that amp is a 5 channel amp

im curious , is the 2011 the same? I have some JL Audio 6 x 9 i want to use in the rear doors, mounting depth id between 3.5 and 4 ". If I need spacers, where can I get them, any advice would be great...also, I am going to add a JL audio amp, any good mounting locations? im good at installing everything, would love to put it under the driver seat, but how... any assistance would be great..thanks

Does anyone know if should hook up my audiocontrol lc6 the same way as this??

But all i want to hook up is my front & rear doors plus sub.

6.5 alpine type-r comps for front doors
6.5 rockford fosgate p1 coax rear doors
2 10" mtx thunderform enclosure
kicker 650.4 amp for front & rear doors
Audiopipe 1300 mini for subs

Going off of what was previously provided for the 8 channel:
channel 1 was the rear door speakers (which were the closest to full range frequencies that I could tell)
channel 2 was the front door speakers (low to mid frequencies only)
channel 3 was the dash LH and RH (high frequencies)
channel 4 was the subs LH and RH (low frequencies)

On your LC6 I would sum everything together with your Font doors & dash speakers + the sub. The was I see this is you are getting the full spectrum of sound into your LC6.
I originally was considering installing the LC8i, but the more I think about it I have no use for the Aux input it offers nor see the need for 4 inputs/outputs.

pin 1 gray with purple stripe (LH front door -)
pin 2 gray with yellow stripe (LH front door +)
pin 3 green with purple stripe (RH front door -)
pin 4 green with yellow stripe (RH front door +)
pin 5 green with brown stripe (sub +)
pin 6 gray with brown stripe (sub -)
pin 7 gray with dark green stripe (LH rear door +)
pin 8 gray with light green stripe (LH rear door -)
pin 9 green with yellow stripe (RH rear door -)
pin 10 green with gray stripe (RH rear door +)

So is this all what i need to tap into

I don't see why that wouldn't work either. Front & Rear Doors + sub. All frequencies would be covered. Worst case if something seem to be missing in the sound you could always change the hookup.
I wish I had a solid answer for what works. I'll be finding out myself in a few weeks.

This is exactly what I plan on doing with the lc6i. I will be re-installing my RBZ.

RBZ head unit
lc6i
3.5 JL in dash (built in filters)
5.25 Alpine front doors(built in filters)
6x9 ALpine rear door(built in filters)
10" dvc single Polk sub/sealed box
Fozgate 100 x 4 amp for the dash and front doors
Kenwood Excelon 5ch (3 way mode for 6x9s and the sub)
Disconnecting the factory center channel and headliner speakers

Once I am done, I will be hooking everything to a spectrum analyzer to help tune everything in....never done it before, but I can borrow the equipment from work. Should be pretty interesting by the time I'm done.

Red, keep us posted on your install.

Well i geuss im back to square one again......I took my lc6 to get installed and they said its going to sound like crap because the lc6 dont have no summing feature or eq,so he said i could do the lc6i for the summing but then i have no eq to adjust anything that is lacking sound.....so he suggested the rockford fosgate 3sixty.2 and told me about what it is and what it does,so i said sounds good and then he told me the price 550! i was not willing to pay that much but he said if i want it to sound good this is the route i should go........This sucks!!! All this headache just to keep my factory nav unit.......So i have been looking online for the 3sixty.2 and its either sold out or discontinued everywhere i look.

Is anyone else having this problem?Or what are you using with your factory nav unit?
 
#19 ·
Damn, I feel like an idiot. I assumed you were talking about the LC6i...I didnt know there was such an animal as that. I've been looking at all the information on the lc6i which does have the summing. I apologize if I confused the topic. I am still going with the LC6i, it seems to be the best quality bang for the buck out there. As for hooking up the amp and sub, you can do this with the lc6. Just tap into the factory rear door speakers, or the actual sub output under the rear seat.

Im prolly puting mine under the drivers seat,4 channel is behind the driver side back seat on the wall,Im going to start wiring for the lc6i today since i still have the lc6 plugs that way when the lc6i gets here all i have to do is plug it in,everything else is installed except the tweets for my components(not sure where to put them yet,thinking about taking the dash 3.5's out and making plates out of plastic for the tweets to mount to)

Ok a couple questions now that i have everything apart...

1.My kicker 350.4 is going to be powering the front and rear doors so am i still tapping into the factory amp speaker wires for the front and rear doors,and if so do i still need to run speaker wires from the factory amp harness to the kicker amp or will the rca's send the signal without running the wires?

2.Power,can i just tap into the factory amp harness for power or should i run power from the battery to the audiocontrol?Ground also or just make my own ground?

Geez yesterday i thought i had this all figured out.....lol

Or if someone wants to just call me 734-341-8093.....thanks,im having back surgery wednsday and im trying to get all this done by then......lol
