Kyblack76 Posted August 30, 2013 Report Share Posted August 30, 2013 If I'm thinking about it right, then the reason it doesn't clip at full gain is cause the head unit output voltage is so low at the 25 that the gain on the amp can never get to the point of matching the headunit output voltage. I'm sure someone will correct me if I'm wrong but that's what my thinking is. NO, Your right.. because, he didnt DO THE FIRST STEP...

b0r Posted August 30, 2013 Author Report Share Posted August 30, 2013 Ok, let me just put this out there because my understanding of the DD-1 is clearly not on par with the communities. When I set my system, I followed EVERY direction as closely as possible and ran for 2 years without a hiccup or any heat. My buddy wanted more bass than I had, because my listening volume was 32/50, but I set it at 47/50, so technically, I could go to 47, but my ears would be pierced by my speakers. In his truck, the sub hits so much harder and is louder when we set the gain by ear. When I grabbed the DD-1, I said to myself: "This device detects distortion. Excellent. We can't listen to this at 47/50, so we will leave the volume on 25, and this should tell us if it's clipping." My assumption was: If we leave this at 25, when we listen to music, 25 IS THE MAX, and the sub will be playing at it's maximum potential. Is this not the case? Let's say his max without distortion is 47/50. Wouldn't we have to play it at 45 to get close to the MAX? My idea was LOGICAL to me, but apparently I'm missing a critical point. Essentially, we can never hear the sub at it's full potential unless........? we turn the door speakers down at the HU? Quote Link to comment Share on other sites More sharing options...
sprkn_ranger Posted August 30, 2013 Report Share Posted August 30, 2013 Am I wrong with my theory Kyle? I'm not 100% sure of it, but it makes sense in my head lol 1 Quote Check out my build log! 4 Havocs in a blowthrough http://www.stevemeadedesigns.com/board/topic/187506-sprkn-rangers-blowthrough-build/ Link to comment Share on other sites More sharing options...
Karkov Posted August 30, 2013 Report Share Posted August 30, 2013 but even in the instructions it says that you set amp gain after you know your HU level for distortion. and it says that in the setting the sub amp directions. 1 Quote 2007 Chevy Tahoe (SOLD) 12 ~ FI Audio X series 10" w/BP option 2 ~ DC Audio 5.0K @0.67 3 ~ DC Audio 5.0K @1.0 2 ~ PPI 3 way sets (not installed yet) 1 ~ RF T400-4, 1 ~ RF T600-2, 1 ~ RF T600-4 4 ~ CT Sounds 5.25" Strato comps (rear fill only) 1 ~ XS Power D4800 1 ~ XS Power D3400 8 ~ XS Power XP3000 160 stock alt, Mechman 370 Elite, 185 DC Power 320+ Sq.

b0r Posted August 30, 2013 Author Report Share Posted August 30, 2013 And the grounds are OKAY i'm pretty sure. I think the amp is roasting because we were clipping the dog shit out of it. User error, but a lack of understanding how it works more importantly. There was no distortion, though. The sub hit deep and hard with no issue.

Karkov Posted August 30, 2013 Report Share Posted August 30, 2013 Also, you can detect the HU for distortion by itself or through the amp same as like the amp.

b0r Posted August 30, 2013 Author Report Share Posted August 30, 2013 but even in the instructions it says that you set amp gain after you know your HU level for distortion. and it says that in the setting the sub amp directions. Correct, and I knew that going into this. I just figured if we "made our own" max for the HU that it would pick up distortion at the new level. User error and not knowing how the voltage worked.

Cox Posted August 30, 2013 Report Share Posted August 30, 2013 I honestly don't understand either because it makes sense to me what you saying.
