Ive got a 2014 e63s amg and replacing all 13 speakers in factory locations with the hertz mille legend line up. im going for maximum bass output ,clear, warm and loud. Mosconi 130.4 for the tweeters and midrange (wouldnt mind changing up if im not sacrificing power or sq since they are 900usd a piece). Salt 200.4 for mid-bass 6.5s for max bass. Sundown xv4 10 in 2.5cuf tuned to 33 on a taramps big boss 3k Running through a alpine pxe x09 16 channel dsp. I know i need a toslink adapter to keep oem headunit so i will be going with the MOBRIDGE DA-G2.STANDARD MOST150 OPTICAL MERCEDES PREAMP to retain all steering wheel buttons gps voicing and other assists. will upgrade my under hood battery to a strong agm and put 2 glowe voltage series 2 in the trunk. 390amp alt from singer alt is being built atm as well. rip out the interior sound deadener everything get baffle rings whole 9 yards. Again i am going for maximum bass but still want to be clear af and loud af but warm not bright sounding. if there are other speaker options that have more bass more clarity more loudness for around the same price please let me know. this is my first full sound system and tbh have only installed subwoofers in 2 cars prior to this. any feedback, suggestions and advice would be much appreciated.

 

So you just bought the E63S very recently ?
If so, I suggest you spend your $$ on mechanicals, its an aging 11 years old car with very expensive M157 engine.

I rather listen to the roar of M157 engine and exhaust ( even stock ones) than any sound system....cause me older now 50+
I would listen to music properly in a proper sound treated room, but no more loud music, but quality music with good imaging on DSD media

Give it some thoughts and love, them mechanicals..... if you want to keep the car say 5 more years............

 

ive owned my car for well over 3 years its in top condition and everything is taken care of. i am talking about upgrading the sound system not the engine. please stick to the topic thank you!

 

That is good news, on the mechanical side.
I can't advice on sound system , I stop doing audio for cars ever since stock set-up is decent already, like since 2011.

I can help take a specification look at your 390 amps custom alternator............ get its power curve at cool 25C and 80-100C hot temperature, based on ENGINE ( not alternator) brake hold idle speed of 550 RPM and to 2,000 RPM.
My Valeo 200AMPS in the tropics, when heat soaked already, at idle and brake hold 550RPM , can not produce more than 60 amps and I could be in deficit mode. if 650 RPM and up OK.
The problem is high power consumption at idle, because alternator needs ALTERNATOR 3,000 RPM for maximum power.
If your car uses EPS electric power steering, that is up to 80AMPS sucker at high degree turn, say a U turn or similar.

Becareful where you will take the extra power demand/source from.
At 10.5V or below, many modules may declare under-voltage DTC if the occurence stays for a few seconds, but the DTC could also be weird ones not stating low voltage.

Good luck on ur audio improvement.....

 

You have the system speakers and interfaces very well planned out with great gear selection.

You'll need to rewire all the speakers with proper copper gauge to pass the PEAK current specially your base spikes with low impedance losses. Speakers are 2.Ohms, right?

You want plenty of strong clean base calls for high currents.
As it is these cars are built to be really voltage sensitive.
The car CAN network may not tolerate the unstable voltage riples. Look for weird random faults.


How about one of those Farad capacitors?


> POWER SUPPLY IMPEDANCE....
Lastly about not overlooking the return side to ALT. MB uses a single economy GND strap mounted all the way low near exhaust line.

What current flows out of (+) must come back on (-) side. The impedance of power supply integrate the GND return.

I would add TWO more straps between chassis and engine.

The voltage ripples are created by high peak spikes from power supply + wiring impedance.
Less ripples is from lower impedance of every item in the power delivery.

 

That looks like a solid plan and really good system. Check out PSSounds on Youtube. One of Peter's demo vehicles is an S550, and while it is not an E63, there is some universal Mercedes info to be learned from him. As for speakers, there are many quality brands out there you can't really go wrong with. I would go with speakers that I could listen to in person. If I can't hear them in person then I would buy the ones with the best support in case they don't sound like you want. Maybe another option, instead of replacing all 13 speakers, you could take the money you planned for all 13 and put that into a higher end 3-way front stage and keep the rear factory speakers as-is.
