Dragonware Posted July 29, 2020 Report Share Posted July 29, 2020 Hi Guys Something strange im using Sundown Components on my front doors and Sundown coaxials on my rear. The Amp is Taramp DS800x4 . if the amp is set to highpass at Volume 17 the front components start to crackle. Amp gains are moderately set. the SMD DD-1 says i can go up to vol 22. So i switched the amp crossover to full range took the volume up to 23 no crackling but the components and coaxials are not putting out too much bass and it sounds farty. any ideas or sugestions ? there is an Audio Control LC7i in the mix and the factory headunit is set to flat. unfortunately the amp does not have adjustable crossovers My Build log : http://www.stevemeadedesigns.com/board/topic/170934-dragonmobile-re-audio-2300rms-stealth-build-08-focus/ Current System 2020 Ford F-150 XLT Supercrew Audio Control Epicenter Audio Control LC7i Taramp PRO 2.6 DSP Taramp DS4x800 - Highs Taramp HD3000.1 Mids Taramp MD5000.1 Bass 8 x DS18 6.5 Pro x6m - mids 2 x Soundsteam SST-05 Bullet Tweeter 2 x DS18 TW220 Super Tweeters 4 X SkarAudio EVL-8 BASS Big 3 Yellow Top Link to comment Share on other sites More sharing options...
1point21gigawatts Posted July 29, 2020 Report Share Posted July 29, 2020 Do you have some spare rca cables? “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...
1point21gigawatts Posted July 29, 2020 Report Share Posted July 29, 2020 Also, where is that amp grounded and does it share a grounding location with any other device? “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...
Dragonware Posted July 30, 2020 Author Report Share Posted July 30, 2020 I can try different rca cables just curious how would the cable be bad if switching crossover on the amp from highpass to full range solved the crackling but just introduces to much bass to the doors. the amp is connected to a ground bus that goes to the secondary battery and directly to the frame of the truck. the LC7I however jumps its power and ground via 18 guage off this amp if that matters My Build log : http://www.stevemeadedesigns.com/board/topic/170934-dragonmobile-re-audio-2300rms-stealth-build-08-focus/ Current System 2020 Ford F-150 XLT Supercrew Audio Control Epicenter Audio Control LC7i Taramp PRO 2.6 DSP Taramp DS4x800 - Highs Taramp HD3000.1 Mids Taramp MD5000.1 Bass 8 x DS18 6.5 Pro x6m - mids 2 x Soundsteam SST-05 Bullet Tweeter 2 x DS18 TW220 Super Tweeters 4 X SkarAudio EVL-8 BASS Big 3 Yellow Top Link to comment Share on other sites More sharing options...
1point21gigawatts Posted July 30, 2020 Report Share Posted July 30, 2020 Thats what I was thinking too when it came to the rca’s. That’s why I then thought it could be a ground loop making the noise or the loc malfunctioning and making the noise. So then I asked about grounding locations. Ground that loc to the chassis on its own ground. That should fix the problem. And it’s not smart to have the positive feed of that loc jumped from an amp either. Use a distribution block to separate it or wire it straight from the battery. But the loc ground is what’s causing that noise. “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...

1point21gigawatts Posted July 31, 2020 Report Share Posted July 31, 2020 You are welcome. You could of said thanks on my post and gave me a rep point. That’s crazy when people that have been on this forum for a while say thank you and don’t post a thanks point on said post they say thank you for. By clicking like or thanks so shows respect, thankfulness and decency.

Dragonware Posted August 4, 2020 Author Report Share Posted August 4, 2020 Just an update i tried switching the RCA from front to Rear and having the highpass crossover set on the amp. The Crackling moved from the front to the back. so you could have been right bad RCAs. I will replace them and also move the ground while im at it and let you guys know.

Big daddy8 Posted August 4, 2020 Report Share Posted August 4, 2020 It could be RCA’s, but it could also be a bad RCA plug on one of the pieces of equipment, if you switch the RCA’s and the noise is still present, I would also check if you have Continuity between the grounds on the RCA at the amp end , and with the RCA is plugged into the amp check that you have continuity between the grounds of the RCA close to your source.

But whatever. only just now seing this post I always say thank you in a comment when i get help. You are right I have been here long but I honestly never knew the importance of the link or thanks. I also never knew that you gain any sort of points from me doing it or I would have been doing that to all the ones who have helped me in the past. Apologies. Didnt think this was like facebook or youtube where likes mattered that much.
