Are the two positive inputs at the DC5K amp the same positive?


Recommended Posts

I am doing some rewiring and was wondering if the positive at the amp is one big block and vice versa for the negative. In other words, does it matter where the positive from sub 1 and sub 2 plug into at the amp's positive inputs?

Diagram 2:

Method 1 (my old method) - I have twisted the 2+ and 2- together and ran them into 1 speaker output.

Method 2 (trying to do) - I will wire each sub in series on its own up to 2 ohms (diagram 2). I will then parallel them at the amp (diagram 2) BUT my question is, does it matter which positive input I plug it into at the amp?

So looking at Diagram 2, would it be bad if the negative orange and negative blue wire switch places at the negative input of the DC5K amp?

correct. they are connected internally.

If I answered you in a well mannered, informative way, you asked a good question or had a good attitude. If I was an asshole, you asked a stupid question or you had a fucktard attitude... or I was in a bad mood.

They are connected on the inside. There are only 2 positives and 2 negatives for wiring convenience ;)

Going to thread jack my own thread so I don't have to create a new thread.

The box CJ18 built for me is tuned to 35hz. My old box was tuned to 30hz. Subsonic filter is currently set to 25hz.

Should I set my subsonic filter to 30hz for the new box?

Play a 60-20hz sweep full tilt and adjust your SSF as needed.

Your Method #2 is actually a better way to wire it up (assuming you're using the same gauge wire on both methods).

You're dividing the current up on a separate cable run to each sub rather than pushing all the current through one wire.

Less current through the wire = less voltage drop.

Not that you'll get much with a fairly short cable run to the subs but every little bit helps.
