Crump Posted July 25, 2009 Report Share Posted July 25, 2009 I plugged in my 4 channnel for testing before my sub amp was plugged in and i had 0 noise. So im like great it must have been the power wire thing, so i plug in my sub amp and boom ground noise through the speakers. I dont understand it, the only thing connecting the amps together is the startup wire, from amp to amp. and where they plug into the battery, need some veteran help, i dont want to ground my rcas, so i just want answers.

Colin - STAPUFT Posted July 25, 2009 Report Share Posted July 25, 2009 Could be the sub amp pulls so much power that it interjects noise back through your grounds into the other amp? Are they both grounded together, are they grounded to frame, and do you have the big 3 done? I have had something like this happen before- everything fine and then I add an amp and suddenly there is noise everywhere. What's your grounding and electrical like? 12 - 12"s in the STAY PUFT 1989 Chevy Astro Build & Comment Log Un-Interrupted Build LogYouTube Channel Chevy Trailblazer 5.1 Dolby Digital DTS Install You have a beard of a mysterious sea captain.

What's your grounding and electrical like? i agree. you added another load to your grounds and now they are restricted enough to give you noise. beef up your grounds If I answered you in a well mannered, informative way, you asked a good question or had a good attitude.

What's your grounding and electrical like? My battery is grounded to my chassis and i grounded my amps to the battery. I dont see that as being a problem. i agree. you added another load to your grounds and now they are restricted enough to give you noise. beef up your grounds My ground from my batt, is 1/0, 1/0 to my sub amp, and 4 guage ground to my 4 channel. My sub amp is a RF T-1000-1bd and my 4 channel is the RF t-400-4 Team gg Team doa Installs I have doneMy 2010 Rebuild 144 db so far....2 DC xl 10s Firing into cabin on a RF 25002 12" AQ HD's powered by a Saz 2k + Lots o Mids+Highs Link to comment Share on other sites More sharing options...

Crump Posted July 27, 2009 Author Report Share Posted July 27, 2009 Where is your head unit grounded to? Do you have an upgraded constant hot for your head unit? My ground unit is just the ground to ground black-black wire. The constant i believe is upgraded, is that the wire to the fuse box, if so then yes the wire is upgraded.

kanes_disciple Posted July 27, 2009 Report Share Posted July 27, 2009 First off do you got your power wire ran by itself down one side of the car and the RCA's on the other side? Stupid question but I know that will cause interference. I ran my main ground from the chasis to the Kinetik, and then from the Kinetik to my amps and I have no interference. I would say make your main ground as short as possible and check the chasis for any paint and if there is any there scrape it off.

lanman31337 Posted July 28, 2009 Report Share Posted July 28, 2009 Try grounding the head unit to the battery, or even try grounding it right to the amp ground. 2 - Audiopipe AP30001Ds 1 - Lanzar Opti Scion 600.4 4 - Lanzar Optidrive 1232D's 1 - Lanzar Opti 5.1 1 - Lanzar Opti 6.1 1 - Lanzar Opti 6C midbass 1 - Alphasonic PCT6551 1 - Lanzar VX830 1 - JBL 22 band EQ 1 - Lanzar SDBT75NU 1 - AudioControl Epic160 Link to comment Share on other sites More sharing options...
