OEM intergration

Does anyone have any opions on the Alpine PXE-H650 or the Audio control LC8 as an OEM intergration foundation?

Also I found this site that if you don't want to go all out they have a plug and play system that replaces your factory standard/premium speakers used with current factory amp with an additional RF amp to push a sub enclosure that fits into the factory "spare tire well".
Has anyone looked into this? http://www.bavariansoundwerks.com/ca...eaker-Packages

What is your OEM audio system?

The LC6i can be used instead of the LC8 as what is needed is only the front and underseat woofers OEM amp outputs to create a low level, full range signal. The LC8 has an 8-channel input which is excessive for this implementation.

You can use instead of any Audiocontrol active LOC, the Cleansweep and its summing device, which in addition of summing signals to create a full range signal and ouputting a low level signal, it can also flatten the signal response of the OEM amp.

You need to sum and low level convert the very high level OEM amp outputs (up to 40V peak) before any downstream amp or processor.

The H650 is a nice processor, however it is the kind of procesor that you either have to like what it does or simply don't, as there is a extremely limited set of manual adjustments; the full tuning is done thru their microphone in real time and that's it, just manual bass, mid and treble adjustments. In other words, you will be going from the Enhanced Premium Audio system way to the Alpine Imprint way of how your music should sound. It is not going to be fully your way.

This is pretty much what I want to do: Front: pair of MB Quart's or Focal components. Center: need to delete, or use factory amp to power center. Rear: smaller MB Quart's or Focal components for rear fill. Subs: pair of JL 12W6. I have a PPI PCX 4125 and PCX 2200 that I would like to use. Would you still recommend the LC6i with what I’m interested in?
I get what you’re saying about the H650, I've read a lot of mixed reviews. They love it or hate it as far as adjustability. I do believe they all have stated that what it does for the sound stage is worth the money.

If you are going to get the H650 then you need to get the Cleansweep and its summing device, just for two particular reasons: first, the H650 "de-EQ" only high level signals, and you cannot input those 40V peak directly into this device. Second, if you use the AUX input then you can use the OEM volume more freely than using the high level inputs, which specifically are set to be left at a certain volume all the time to accomplish the "de-EQ".

Thus, if you set the H650 to accept an already low level, "de-EQ", and full range signal thru its AUX input you are allowing the H650 to do its Imprint processing more effectively and you will be keeping the OEM control of the volume, instead of using the H650 remote control.

The problem with leaving the center channel driven by the OEM amp is that it could cause strange effects in your Imprint processing -remember, you will be using a live microphone to perform this processing, so if the center channel cannot be tuned completely by the Imprint (as its being tuned by the DIRAC processing in the OEM amp) then the results could be shaky, so say the least.

IMO, either leave the center channel disconnected from the OEM amp or simply get the CDT CS-256 module and wire the center channel in series with the front speakers like I did in my system. Then the Imprint will have full control of that speaker response as it will be part of the new full range, "de-EQ" signal that you are inputting into it.

Technic,
I was just reading an old post of your where you went to the Audison bit 1. Do you still have that in use? How do you like it. I also notice you don't have the traditional set up of subs in the trunk. You are using the factory locations under the seat. How well does that work out?

The bit one.1 really improved the sound quality of the Premium Audio, with a lot of manual tuning abilities and great soundstage. The only OEM speakers that I replaced in my Premium Audio system are the underseat woofers with SWS-8. They really fool people in thinking that there is a small sub somewhere in the car. However, if what you are looking for is the big "boom boom boom" you have to have a dedicated trunk sub.

these are the amps that I want to use. They are huge, but I think if I take out the plastic incert I will be able to build an amp rack to house them.

Anybody know what's under the plastic insert. I understodd there was nothing under there as in you can see through to the ground if you take that out.

You’re right, there is nothing but the heat shield for the mufflers. I will have take out the plastic insert and see if I can fabricate a fiberglass rack that would be deep enough to hold the amps.
