Bass was deeper and louder in previous car, same amp/subwoofers

[MROOD]

So I had a Audi A5

I had a guy install my JL Audio 1000/D Amp to my 2x 12" subwoofers

I think he tapped or spliced in to the original subwoofer cables and created a RCA connection via a RCA converter, so from Subwoofer cable to RCA so I can insert into the Amplifier, the bass was always deep and sounded great.

So I bought a new car and got another guy to install my old gear, but this time via the original factory BnO car system the subwoofer level doesnt work.

Meaning on the head unit I have bass level and subwoofer level, the subwoofer level doesnt work, only the bass level works but the sound is weak and doesnt sound bassy as before

I think the guy tapped in to the door speaker cables and that why I get more mid bass and the subwoofer volume control doesnt work

I think if I tap or splice into the original factory subwoofer cable then I will get the subwoofers working like before?> does this make sense?

Yes, it does. Although from experience, I know that door mounted speakers receive the full audio spectrum. If there is a lack of bass, it may be due to the eq curve set by the OEM radio to protect the full ranges from too much bass. When you say BnO, is it the Bang & Olufsen in Ford vehicles?

yes B&O from Audi

I mean it makes sense to say the door speakers cover the full audio range from high to low, but somthing isnt quite right and to see the subwoofer level button doesnt work suggests I need to try and hack in to the original subwoofer cables

So ive bought another speaker cable to RCA converter adaptor, this has plus neg plus neg cables

this original B&O subwoofer looks like its dual voice coil, so I'm trying to figure what cables connect to the adaptor? would it be black green to plus neg and orange yellow to the other plus neg on the adaptor?

The black and green wires go to the voice coil. Not sure what the orange ones are for.

According to that diagram, yes.
