What did you do to / for your E53 today??

In sound reproduction what sounds bad may actually be good, but incomplete. And that’s what the problem is with the factory DSP. There is plenty of high end frequency. The low end on the other hand is incomplete which creates inconsistent sound i.e. awful sound. You can’t look at it as just, oh he simply added a SUB. I added the missing frequencies, and then tuned them in completely recreating a new sound field. So if you were to hear it, it won’t sound like anything you heard before, because it’s not. It’s been reconstructed.

The factory DSP amp and speakers are more than sufficient. It goes loud enough with out distortion to be unhealthy for your ears. So imo, no need for upgrading. However, I wouldn’t mind getting my hands on a pristine pre LCI DSP amp! Also, I am intrigued by the fact it is a 8 ohm system, and not 4. Car audio is usually 4 ohms.

We'll have to agree to disagree on this one. Fill in the bass frequencies and you're still left with a system that has pretty underperforming mid and treble, IMO.

I 100% agree that adding a sub is the biggest bang for buck improvement that you can get in most stereo systems, I just do not agree that the rest of the DSP system is up to par.

I think you’ll be pleased with the stealth box. You will need an additional SUB amplifier to power the driver in the stealth box though. The DSP amp will not power a 10” driver properly and could damage the amp.

The factory SUB is awful when solely relied on for low end frequency. Mine is still active, but it’s been tuned for 200Hz - 500Hz. Before it was trying to produce 20Hz - 500Hz. All I can say is, Good Luck With That! LoL..

Yeah, 20-500 is just dumb. No other way to put it.

TIL the rest of this board takes their stereo system way more seriously than I do

Agreed.

However I noticed in your profile that you have an ‘04 E53. There was a change in audio equipment from the original build E53’s. The schematics show a completely re-engineered harness for LCI. So quality my have changed one way or the other. That may be a factor as well.

The treble on mine is ear splitting! No problem there. It was the Mid range that took hours to balance out. But once I got it, I was left with a solid sound field.

So where I agree to disagree is that the equipment imo is not sub par, but poorly tuned and lacking a complete range of frequencies to produce a balanced and quality sound field.

Yeah Pops though it was a wise idea to convert his 8 year old son into an audiophile. I’m not mad, but definitely gained some unneeded ocd.

I currently have in the truck
-Kicker CX800.1 mono amp for the sub
-Kicker CX360.4 for the front and rear speakers
-Wavtech link8 LOC
-Infinity Kappa speakers front and rear
-SkarAudio 1" tweeters
-Earthquake SWS 6.5inch shallow woofers in the OEM DSP box

*Not all the highest end stuff but the previous owner did a lot to make this work without upgrading the head unit. Some quick changes should prove worth it.

Unfortunately this is all run through the OEM stereo, I just ordered the Dynavin D8 Pro head unit today & will run RCA cables directly to the amps & Sub. I should probably do that first before the JL Stealthbox but I get a little ansty.

That factory sub enclosure is definitely holding you back. You’ll definitely gain sound improvement with the stealth box install. Most likely even running the factory head unit.

I'm somewhat of an audiophile myself - which is why I don't bother with stereos in cars. Cars are a "sub-optimal listening environment"!

For seriously listening pleasure, I sit at home in front of Magnepan speakers driven by Perreaux mono-blocks.

With the lights off. And the phone on silent. And everyone out of the house.

That's OCD!
