I've only dealt with pico fuse in my car, but other issues in others. i had a pioneer H/U but got it changed for a kenwood Which Kenwood HU? You need to have your grounds on clean metal and secured very well. Your RCAs are far away from power wires yes? kdc bt848u well my H/U is getting the ground from the factory wiring harness and yes my power wire on the driver side and RCAs on the passenger side Edited January 24, 2012 by ALEX 323 Quote aka KHRISS Link to comment Share on other sites More sharing options...

dereileak Posted January 24, 2012 Report Share Posted January 24, 2012 on thing I found is if the gain on the amp is set wrong plus any other gear, I have great strong grounds, grounded head unit RCA;s, I have all premium quality very well shielded RCA's, and I still had engine noise, used my dd1, set my 30 band eq, headunit, with doesnt clip even 40/40 at 0db, and the 3 way crossover, 4 amps, and its all gone, all the engine noise, just be causing one level somewhere was too high, probably the line driver in the eq, and the gains were to high, you will see a point if you turn it that engine noise will kick in all of a sudden, so that can be part of it, like said earlier, bad grounds, bad rca's, it can be tough to fight, found its worth the extra time always to do everything at a very high quality through the build, and you will have less problems down the line, im sitting like 10 feet from my screen so im not gonna proof read this, lol, hope it helped Quote 2006 Mazda3 Hatchback Black 5 Spd ManualPioneer 4300DVD2 Sundown SA-12 (34hz Tune, 3.22 cubes, 14.5 inches per cube, Triple Baffle)Kicker 10ZX2500.1 (2845 RMS) Sub AmpKicker 11ZX650.4 (705 RMS) Mid Amp -- (3 Amps)Kicker KQ3 Active CrossoverKicker KQ30 EqualizerKicker 09QS60.2 Components (Woven Carbon Cones)Kicker 09QS65.2 Components (Woven Carbon Cones) - (3 Sets)2/0 Gauge Electron Beam Technologies (3 Runs, 2 +, 1 -) 1/0 Gauge KNU Kollasal Flex (1 Run for -) 300 Ft Kicker X-Series 16 Gauge Speaker WireXS Power D3400 (Rear)XS Power D3100 (Front)Singer Externally Regulated Alternator (Being Built)+ The Love for Car Audio and BASS <3UBL Build Log <------- Click Here-------> Normal Build Log (For Comments) Link to comment Share on other sites More sharing options...

Your RCAs are far away from power wires yes? my H/U is getting the ground from this I also took my ground wire and extended it to a new better ground, where my security system grounds and everything, works good there, can help, as factory grounds suck usually, but usually work, also ground the outer casing of the rca's to the headunits casing Quote 2006 Mazda3 Hatchback Black 5 Spd ManualPioneer 4300DVD2 Sundown SA-12 (34hz Tune, 3.22 cubes, 14.5 inches per cube, Triple Baffle)Kicker 10ZX2500.1 (2845 RMS) Sub AmpKicker 11ZX650.4 (705 RMS) Mid Amp -- (3 Amps)Kicker KQ3 Active CrossoverKicker KQ30 EqualizerKicker 09QS60.2 Components (Woven Carbon Cones)Kicker 09QS65.2 Components (Woven Carbon Cones) - (3 Sets)2/0 Gauge Electron Beam Technologies (3 Runs, 2 +, 1 -) 1/0 Gauge KNU Kollasal Flex (1 Run for -) 300 Ft Kicker X-Series 16 Gauge Speaker WireXS Power D3400 (Rear)XS Power D3100 (Front)Singer Externally Regulated Alternator (Being Built)+ The Love for Car Audio and BASS <3UBL Build Log <------- Click Here-------> Normal Build Log (For Comments) Link to comment Share on other sites More sharing options...
