DD1 and Alpine PDX V9

[Ctheodores]

I have just purchased the SMD DD1 and Alpine PDX V9.

 

my question for starting to tune my amp. Do I need to probe the negative to the negative of the ground wire itself or + and - speaker wire?

 

does it matter which speaker wire I probe to find out the max volume of my HU prior to clipping ?

With the stereo channels you just need to use one of them, left or right, say you check front left and rear left.

 

Then the sub channel since is a mono channel you have only one output to check.

 

Notice that the test tracks are not the same for the mids and highs channels than the one for the sub channel.

 

Check the manual to know which audio tracks you need to use.

 

You need to connect the DD-1 to the amp as if you were connecting a speaker or a sub.

 

Please read the manual a couple of times and make sure you understand everything before starting your tests.
