jroshandtap Posted June 22, 2011 Report Share Posted June 22, 2011 Alright, many of you have tried to help me out on here with a couple topics and I appreciate that a lot, but I have given up on this stereo. I have downloaded the mauals for my amps and hooked them up exactly how it describes and its getting me nowhere. My amps are still the orion 1200d's. Each amp has its own 4 gauge power wire going to starting battery. Each ground was reinstalled lastnight to knew locations, bare metal to bare metal ground terminals. RCA from head unit to master, then master to slave. 2 12" woofers wired parallel to 1 ohm to each amp. 12 gauge speaker wire. Brand new 150 amp anl fuse for each power wire. All that said, im still getting a humm /chatter coming from subs when head unit volume is on 0. If i play with the gains it goes away but the gains are at like less than half way. My best guess is lack of power? I have not done big 3 upgrade, 1/0 gauge is being shipped as I type. So is that the problem, the lack of power? Because if its not that it has to be the amps right? As of 2 weeks ago they both ran perfect. I just want to figure it out cause im going crazy over these things. Do I need to install a secondary battery to power amps.? Maybe even 2 secondary batteries, 1 for each amp. I mean they are only 1200 watts, im not producing that much power, I could understand if I was SMD with 30k watts! Lol just please someone help me out. I need some good news for a change lol Quote Link to comment Share on other sites More sharing options...

jroshandtap Posted June 22, 2011 Author Report Share Posted June 22, 2011 Almost forgot, my amp powering my mids and highs is now producing an engine whine! Lol it too has its own power, ground is same as others, bare metal to bare metal terminal. RCA are some monster brand ones, cost like 40 bucks. Fuse for power wire is fine. Its some little 3 or 400 watt amp crunch made like 8 yrs ago. The whine just started happening lastnight after I relocated my grounds. I've had no problems with that thing at all till then. The head unit I have is a pioneer DEH-P3000IB, it too does the job fine. Or so I thought. Could the ground for the head unit be loose? Should I ground the RCA using a peace of wire?

matt402 Posted June 22, 2011 Report Share Posted June 22, 2011 yep, ground the rca's on the back of the hu. Quote Link to comment Share on other sites More sharing options...
TeamHT Posted June 22, 2011 Report Share Posted June 22, 2011 Bare metal sometimes isn't enough when grounding. Make of said vehicle and exact locations of grounds. Ground the HU? Quote Tell me...does this smell like chloroform to you? Link to comment Share on other sites More sharing options...
Skullz Posted June 22, 2011 Report Share Posted June 22, 2011 You'll want to ground the rca's on the pioneer H/U to solve that issue, next try unplugging the rca's from the sub amp and start the car and see if they still make a humm. How close did you run the rca patch cords to the power wire you ran to the back of the car? What kind of car is it by the way?

jroshandtap Posted June 22, 2011 Author Report Share Posted June 22, 2011 2005 ford explorer, 4x4. 4.0 v6. All three grounds are under rear bench seat. Each is secured using 3/8 bolt with washers on head and nut sides. And I didn't mean to say ground the h.u. I meant ground the RCA'S Quote Link to comment Share on other sites More sharing options...

BassJunkie Posted June 22, 2011 Report Share Posted June 22, 2011 (edited) Gotta love the good ole pioneer humm. I do this to every pioneer I install. Call it ghetto if you want but its inside the dash so i couldn't care less about how it looks, it simply works.

jroshandtap Posted June 22, 2011 Author Report Share Posted June 22, 2011 I ran power and RCA'S on both sides of the truck. Each side is for each amp. Quote Link to comment Share on other sites More sharing options...
