I've heard that. The reason I have been using tones is that there is (typically) a VERY identifiable point where distortion can be heard. I don't get that when listening to music, at least not as black and white as a single tone. I guess if I'm going to try to use the tone, I should open the...

Hey all. Long time no post... It seems everything in the powered sub is snug. At this point I'm forced to admit I don't know what I'm listening for... I turn up the head unit to it's distortion free limit, play a 40, 50 &/or 60Hz signal via USB thumb drive and turn up the level on the sub... I...

10-4, will do.

Hm. I may have to pull it apart. With a 50Hz tone I hear what I think is distortion before I get to 30% of the level knob. And it's NOT loud enough... I'm interested to see what the scope says. Planning to try by ear in a minute with a 60Hz tone ... Maybe the enclosure was vibrating?

This is a Sound Ordnance B-8PTD from Crutchfield. I guess it's their house brand. I can already tell I might be replacing it, though. Even with the crossovers in place, it seems muddy and doesn't pack much of a punch. I prefer "tight, clean and punchy" to what it seems to be putting out...

PROGRESS! If you recall, I was suspect of my universal power block I had running my o-scope. Long story short, that was DEFINATELY introducing a lot of noise to my readings. This week I received a new 9v power supply and the BNC to RCA adapter for my o-scope. I had clean .wav test tones from...

I currently have my head unit completely flat. No EQ, no effects. I AM running crossover from the head unit, however. HPF to the mains (2 pair 5.25") @ 100 Hz, 12 dB/octave slope. LPF to the powered sub @ 80, 18 dB/octave slope. 1. Should I clear the crossover settings while testing the RCA...

Oh, yes. I am fully aware. I know what it SHOULD look like and how to read a clipped signal. I just don't know enough to know what the problem is. So, I'm trying to clean up the power source, and the connection, and we'll see what happens next.

Could have been 10, could have been full blast (35). The wave didn't visibly change regardless of the volume at the head unit.

You guys are awesome. Thanks for all the help so far. @dragon.breath I almost went for the 9v pigtail. Time will tell if I choose poorly. @dangerdan86 I just ordered that bnc/rca connector. Thanks for the link. That 60hz'ish result does not accurately reflect the tones I was using at that time...

1. How did you connect to the RCA's? 2. What can I do to confirm my scope is functional? (60hz is where a lot of noise lives. I'm getting a better power adapter to start. I think the junk one I found in my basement storage is likely part of the problem)

I was very careful with that switch. It has been in AC mode during every stage of my testing.

Sorry, I added that when I registered, I thought it would show up like a signature or something HU: Kenwood KMM-BT328U I tried connecting the alligator clips to the RCA outs (first with one jaw poked inside and the other clamped outside, then trying to clamp to just the outside), but got no...

Hello, all. Brand new here. I apologize in advance for the long first post. I'm trying not to leave out any details. Recently installed a new head unit, RCAs to a 75w 4ch amp powering 4 5.25" speakers. And a compact 8" powered sub. I also purchased an inexpensive oscilloscope to check output...
