40Hz Sinewave of Jl Rd 1000/1

So the sub rca output is clean until after the amp? Where was the rca output measured at deck or at the end of rcas by amp? Did I see any sub amp does this? I can’t remember.. have you tried a different deck ? See if that solves the problem?

The sub amp location is in the trunk. First I took the sub output RCAs out from the amps input socket. And tested both L and R (so for this like you said, I tested the end of the SUB RCA's coming out from the deck). This implies that the deck's output tested through the end of the RCA cable coming into the trunk is clean all the way. With this in mind we have eliminated the headunit as a potential culprit.

 

Next I connected the sub RCAs back to the sub amp's input socket and tested the amp's speaker terminals. This signal however was not clean, as you can observe in the video.

 

I finally swapped the JL amp with a Mosconi one I had. Tested again the speaker outputs in the same conditions. This signal was clean and looked smooth. With this we conclude that the JL amp is somehow not delivering what it should.

 

But even with all of this, even with a clean bass output from Mosconi, I always experience MUFFLED BASS in this car. In my previous post I explain the situation more in depth.

 

I do not want to believe that a car's acoustic properties/inner properties can influence in sucha negative way, can destroy any listening experience.

 

I really want to deny that this is all exactly because of this, of the acoustics.

 

I cannot experience the sub bass like I used to  know it in this car. This car does not like subbass or something else is happening. Either way this whole thing is overwhelming.

 

 

LE: The negative factory battery wire has near its pole connection (on the wire itself) a tiny black rectangular control device, with a small 10A fuse in it. When I suggested the shop to replace it with a wider more powerful one, they said you can't just put any wire in there due to the small control device attatched to it, which seems to stay in the way of things. From their perspective I should either let it get replaced with a SIMILAR one (wire+control device attatched) or say goodbye to the idea. Everytime I tried suggesting any electric upgrade I was immediately put down (like who am I to even dare to have such basic knowledge). So according to them, the electric upgrade chapter was out of the question.

Not to mention the other countless car audio shops I went to. No matter what I wanted, either couldn't be done or I was a major idiot for even daring to ask. Here in Germany and Romania too, after so many negative experiences I decided that I must stay the f away from these specialistsshops, esoecially when it comes to bass. Figure it out on your f own.

 

Saving money for a long time, daily dreaming about your first new car.

 

Getting the car, putting a new system in it, lying to yourself for a while, pretending it sounds good. You have days and days. This up and down game was based on the songs played. Few of them sounded fine. There was always this sinewave of feelings. Today ok tomorrow not ok.

 

At the end I realized it was all a joke actually. Even the "good sounding" tunes were in fact a joke.

 

Then you take it into your own control, you gain new knowledge as time passes.

 

5 years and counting I am still in this game. I still have no concrete answer as to why. All I have are assumptions.
