sub for future reference. so far I just have a JL sub and the stealth box

The sub in the pic directly above yours is the factory unit for E53's so equipped.

No, all of the gear pictured is factory OEM DSP setup. I was just posting for illustration of exactly how many speakers the factory DSP amplifier handles for powering and tuning.

Makes for a very complicated install if going for a full one for one replacement using OEM DSP or BSW type speakers. Hopefully I wasn't confusing anyone. :D

You can get away with less equipment if you are using replacement speakers like Propellerhead is. You can get away with a single 4 channel amplifier if doing that. But you will lose the upper dash speakers if you don't use the head unit's amplification to handle those... and I'm not sure you'd be able to filter the frequencies enough on them, depends what type of Xover settings the head unit offers.

I have upgraded speakers and subwoofer with dedicated amp from BSW. Purchased many years ago. When I installed the Seicane unit I had difficulty with DSP staying on. The 'usual' fixes didn't work so in the end I went to a custom audio shop. We talked about adding an amp for speakers and eliminating DSP amp. I would have needed two amps and the speakers all rewired. Not worth it to me. DSP is now working fine and system sounds great.

Hi beredliner,

I know you solved the dsp issue with your seicane install. Can you share with us how you did that?

It is important to say I am not positive of the proper connections. Also, I think I am the only one here that actually has the Seicane unit installed in a vehicle with DSP. After many attempts at suggested fixes I took it to an audio shop. I had several problems that were interrelated including a failing DSP amp. After replacing the DSP amp they used a $10,000 plus tester to sort the rest out.

However, if I understood what the experts told me, the proper connection is to run a wire from the wire labeled amp or amp control at the Seicane unit connector in the front to the wire labeled amp or amp control on the Seicane harness in the rear. My suggestion is to do a test install over the seats and see if you lose sound after 20 seconds. If so, try this fix.

That seems too easy to believe, bcredliner. I’ll probably be the only other 4.6 owner with dsp to attempt install of the 9” seicAne. I do love the big screen and will look for the newer model with android 8 and 4gb ram. Still their website is not offering official support for dsp models, makes me a bit uneasy about moving forward.
I certainly don’t have a 10,000 dollar trouble shooting machine to assist me if the install goes wrong. :(

Don't expect support from Seicane. I have tried many times. The process is to send an email to China and they don't respond for at least 24 hours. They obviously understand very little english and all questions go to sales then they ask tech and then tech responds to sales and sales interprets what tech said and the resulting answer doesn't have anything to do with the question. Or they ask a question because they misinterpret my question. I would try to find an audio installer familiar with Android based units (all are very similar) for input prior to purchase so if you get stuck you have a go to expert.

Initially, I was sold on the Dynavin unit but went Android based because I can add new apps and updates keeping it from getting obsolete longer. If I hadn't had several other problems that complicated solving the no sound problem I wouldn't have needed help from an installer with high tech equipment.

Sorry for the delay, changed my build. Still Jl audio all the way, but changing my amp selection and adding the fix 86. Its gonna be a couple more weeks. I was rear ended 2 weeks ago on the freeway and my x goes in tomorrow to the shop to start the repair. Figured I should wait til they finish before I install. I did do some sound deadening on my doors though! I'll do the rear end when it's back from the body shop. Updates and pictures should come in a couple weeks. Once again sorry for the delay.

So it took forever, but almost done.
 

2006 4.8is.
I originally got a jl audio fix 86 to correct the signal for my new amp, but that didn't work. For some reason it wouldn't create a full signal. Finally decided to get a new deck. Seicane android 8.0. Unfortunately it didn't come with the canbus so my steering volume controls don't work yet. Seicane has terrible customer service, just an fyi. I replaced my door speakers with jl audio c3 600 components. They fit perfectly into the stock plastic baskets that the original speakers were in. Just some silicone or liquid nails to hold them in place. I ended up putting the crossovers in the doors with double sided tape, gorilla tape. I ran 14 guage wire all the way from the back to each door. The rubber boot from door to frame was tricky, but after some brute strength and cuss words, I figured it out. When you unscrew the boot, there is a large connector. On the top of the connector, there is a small wing pointing upward. I cut that off with snips and that gave enough space for the wire. I used a wire worm, got it from Crutchfield. Taped the wire to it, slathered it in hand soap for lubrication, and it slipped right through. Big pain because there weren't any videos on rewiring door speakers or how to take apart the trim to run wires so I just cussed alot and got through it. As for the tweeters, they were part of the components, 1" tweeters. The factory location is larger so I used foam water line insulation. Bought a piece, cut 1" pieces that fit right around the speaker, then double sided tape on the outside to keep them from moving. They didn't really need the tape, just squeezing the foam tight and stuffing it in should do the trick.
I pretty much copied the amp location from bavarian sound. I fit a jl audio xd700 5v2 5 channel amp. It has enough power to run my speakers at peak rms. I'm still waiting on the jl audio stealth box to arrive so for now I'm using a ported jl audio 10w6 until it arrives.
It sounds Amazing! Compared to stock anyways. I may in the future upgrade the jl audio c2 to a c3 or c5, but they're pretty expensive. I have not yet installed the fro t and rear cameras, or the tv tuner. I'm taking a break til the sub enclosure shows up. I will post a few pictures of the wiring through the door and the tweeter install after I get the sub installed. Oh, also put sound deadened in the doors, you can barely hear anything outside the truck while inside its thumping! No rattles. Windows dow. You can hear it down the block.
