To Mods: Apologies if this post is in the wrong section. I wasn’t sure where it best fit, but I genuinely wanted to hear fresh perspectives outside the usual car audio circles. Appreciate your understanding and allow at least to see if it got any responses at all.
I acquired a car with a “professional” audio system already installed. Its Mercedes s600 1995 I know this particular model very well. Despite the fact that the sound system was built according to all the car audio standards, its sound quality is worse than that of the same car in full factory condition with the original amplifier. Front doors have 6.5” audison prima woofers, but its perform worse than factory ones (i just dissasembled one door and returned factory box with factory speakers )
Car audio has become so entrenched in its misconceptions and commercial interests that it’s nearly impossible to find truly professional answers on forums (with all due respect to this one). Truly high-quality installations are extremely rare. I’m conducting an experiment—stepping away from all the traditional rules of building a stereo system in a car. I’m curious what someone who has never done a car installation might suggest. For example, the idea of placing large tweeters under the rear window—why not?
Initial conditions:
• Door volume: 60 liters
• Factory front doors have factory ported plastic enclosures with 4” midbass and 2” tweeters (~2 liters), which can be expanded to 3 liters or removed entirely to use the full door cavity.
• Rear doors have 2–2.5 liter enclosures with 4” speakers from factory
• Dashboard allows tweeters or possibly up to 3” drivers
• Trunk is connected to the cabin through 4 factory speakers in the rear shelf (Mercedes uses non-standard sizes): 4 openings of 5.5 inches. Can favricate box in trunk, like basically build bookshelf at rear, maybe 2x woofers + 2x big twitters?
• A small subwoofer may be placed in the passenger footwell — about 10–12 liters available for a custom enclosure fabrication or maybe passive radiator
All current components will be removed, im not even telling (until someone asked) to keep experiment clean. What setup would you propose, considering the available installation locations and volume constraints?
Ask if any clarifications needed about initial inputs.
I want use dayton speakers, looking at reference or epique series. Most doubts about midrange and tweetera. Skip amplifier suggestions, most interesting is your suggestion abt speaker setup.
Bugdet is infinite (no im not that rich, just wanna see best possible setup as reference)
Thank you everyone!
