So If I want to run an aftermarket unit, do I just omit the step that deals with the Ven4 and just run RCA cables to the amp from the new head unit?
Here are the components I have:
1 alpine 4 channel amp, to drive front woofer and tweeter (mbquart component) through channel 1 and 2. Channel 3 and 4 for the rears.
1 alpine 2 channel amp for one sub.

So let me get this right....I'm in the process of installing now...I already got the head unit installed and the rca cable routed to the trunk.

cut and connect appropriate wires for the front woofer and tweeter from the oem amp and run those through my crossovers and then to the amp.

Do the same for the rears, but they are not components so just wire them directly to the amp and connect to channel 3 and 4...

Wire appropriate wires for the amp...throw away the stock amp...and here's is where I need your help fanatics!!!

It seems like your on target. If you wanted to make all of your connections in one place and not have to hide speaker wire running to the rear speakers, you could tap all of your speakers off of the factory harness. You're correct, though, in that you don't have to. Basically, ignore anything having to do with the SVEN4 or RCAs, and you're good. One note, you'll need to tap a remote turn on lead for your amplifiers, even with an aftermarket head.

My Ride: 2001 BMW 330CI
Can someone please help me on this; I'm a little confused.

I want to upgrade the sound system in my 2001 bmw 330ci (non H&K) and here are the components I already own:

(1) 2-channel amp w/ built-in crossover, one 12" sub and a capacitor (all Rockford Fosgate).

What I want to accomplish is:
- Use my already own 2-channel amp with the 12" sub for a deeper bass
- Upgrade the front and rear speakers and tweeters (for a cleaner sound)
- Get a new aftermarket 4-channel amp w/ build-in crossover to drive the front and rear speakers.
- Retain my OEM head unit.

I understand that I will need a Peripheral Vendetta 4 to convert the outputs from the OEM head unit to standard RCA.

So if I got this right I'll use channel 1 and 2 from the 4-channel amp for the front speakers and channel 3 and 4 for the rear speakers (high pass only). The configuration would be as follow: OEM Head unit speaker outputs -> ven4 -> aftermarket 4-channel amp -> front and rear speakers

My question is how do I setup the 2-channel amp to the sub? Which wire would I use from the OEM head unit to the 2-channel amp to drive the sub and would I need another ven4 to convert the cable to RCA?

You're better off skipping the SVEN4, and getting an AudioControl crossover that provides 6 output channels. If you don't mind losing fader (front/back) control, one of their less expensive 2 channel inputs/6 channel outputs will work for you. This will replace the SVEN4 in the above write-up. I'm not too familiar with the entire AudioControl line, but there are guys on this board who are. Good luck.

Can anyone advise on the above thread? Which model would I need from AudioControl to achieve this setup, and how would it work?

I visited the AudioControl website and noticed that the LC6 might be the one I need.

Items I would need to complete this set up are:
(1) 2-channel amp w/ built-in crossover to drive the 12" sub (set a low pass) [already own]
(1) Pair of new front and rear speakers
(1) 4-channel amp w/ built-in crossover to drive the front and rear speakers (set at high pass)
(1) LC6 to convert the output signals from the OEM headunit

Can someone please let me know if this setup is correct and would I get a decent sound from it?

Thanks to William and Seth!!

I just wanted to say thanks to the original author, William Quiles, and to Seth for posting this flawless DIY. I've made use of the wiring diagram and front door mounting ideas to upgrade my 2005 330ci with similar a/d/s/ equipment. I'll post a new thread with pictures of my equipment board and additional information.

For now, I wanted to add my contribution to the wiring portion by posting a diagram I made that maps the pins from the connectors on the harness to the internal connections of the amp. I purchased a used non-HK amp from a 1999 E46 sedan and removed the guts except for the small PC board the connector is attached to. The board has six mini connectors on it that are straight-thru signals.

I used 24ga phone wire, solid core, as "pins" to insert into these connectors and mapped the appropriate pins to terminal strips like the ones William used in his original DIY. Viola! A connector for the harness without cutting the harness!

Attached are two pics of how my "connector" turned out, and the pin mapping diagram.

BTW, I made one mistake when I created this. I ran the +12v remote-on wire along with the pre-amp connections. This has resulted in a low level buzzing noise since this wire has power while the stereo is on. So, I've re-routed the wire to alleviate the problem.

I came back here to answer a PM and noticed that this thread wasn't sticky anymore. Does a sponsor not want others to have this information for free? Just curious. See you guys in another year.

Great post. I am definately going to install my own stuff now. Any tips on which line converter to get for a install with 4 channels plus a sub? Also, what is the difference between the "cheap" converters and something like the jl cleansweep or fosgate 3sixty2?

Can we use this to bypass the amp and no cut the wires?? Im more just interested in the connector part and could care less of the ability to convert the signal since i'm getting an Audiocontrol EQS but I don't want to cut the wires.

Thanks

Eddie

It was a "sticky" at the top until Bavarian Soundwerks sponsored the forum. Strange.

What a great post, thanks for taking the time to compile everything!

Like the fella above, I just want to hook up my amp and sub for now. Would it be best to just tap the rear left & right out wires (before amp, leaving the OEM harness in its original setup) into a SVEN and feeding the amp? I've actually already purchased the SVEN4 and I assume that I can just use one pair of channels, is this correct?

Many thanks for any help.

By far one of the best threads I've read here! Allowed me to transfer my amp+sub setup from my E36 into my E46 with ease. Was completed in i'd say an hour max. This should hold me over till I can get my custom setup going.
