[Fake/Counterfeit DD-1's on ebay and Amazon?]

The one I bought had the same image displayed with the "RoyalSell" on it. I think I bought it from SkyHighCarAudio's page on amazon (?) Anyways, it did not have that print in real life, and I got the real product. 🙂

EDIT: 

This is the exact one I bought:

Ok thank you

[Using DD-1 on a 2-Channel]

Hello, I just bought a 2-Channel amplifier to power my new SPL tweeters. I'm a bit confused on how I should use my DD-1 to set the gain properly though.

From the manual: 

5. Using included harness, connect DD-1 to output of amplifier. Connect the red harness lead to the Left Speaker (+) terminal, connect the black to Amplifier Ground. (Note: Most multi-channel amplifiers have the signal on Left (+) and Right (-).

 

So I put the positive lead from the DD-1 to the Left Speaker positive, and the negative probe into the negative power connection on the amplifier? Can I just stick it in the 0 gauge negative, like if I were testing voltage with a multimeter? 

 

I just had to ask here to be 100% sure, don't wanna blow anything up. 😝

thing is I have 2 mono amps so I would need 2 bass boost knobs sadly

I have two amps as well, but I have them in a strapped configuration, which allows me to control them with just 1 knob.

btw when tuning, do you set your bass boost on the amp all the way up (or preference) or leave evrything flat ?

I don't use bass boost on my amplifiers, but I have a remote bass-knob which I turn all the way up, then tune it. It says clearer how you can do it in the manual

Edit: I also have everything else flat, on my headunit for example.

It's just a bit difficult to use it,. For one, factory speakers so it plays the tracks and the sound is annoying when I try to find where it distorts at. the only thing connect to the amp is just the sub wires along with Rca for the line out converter

Yeah 😕 Hopefully someone with more knowledge can chime in and help you out. Good luck. 🙂

Factory headunit with the idrive (navigation screen)

 

Ahh I see. I don't know anything about stock headunits really. But I have a DD-1 my self, and to your second question; In my experience at least (aftermarket Pioneer headunit) the volume levels are different between AUX and Bluetooth for example (by a lot actually). I don't know why that is though.

What headunit do you have?
