hi guys, i am having a bit of trouble with my pioneer 6050?
works fine bar i had to use a ground loop isolater to reduce bad buzzing from a 2channel amp to the fronts.
now the headunit will only work correctly if faded all the way left or right. centerd audio makes the speakers phase out..
this only happens with the ground loop isolater installed.
also the speakers pick up wayyy too much bass even with the bass turned right low on amp and headunit...
rattles door etc.
they are only semi decent pioneer splits but they work fine for what i want.
NB: amp is connected to fronts outs and not sub out ie correctly

so, just to check, this wierdness ONLY happens with the GLI connected, and goes away when you unplug it? (but obviously the buzzing comes back yeah?

The only excuse for passive crossovers is their low cost. Their behavior changes with the signal level dependent dynamics of the drivers. They block the power amplifier from taking maximum control over the voice coil motion. They are a waste of time, if accuracy of reproduction is the goal.

When did your problems start?
What have you changed recently?
Do you get the buzzing all the time or just with the engine running?
Ground loop isolators are really just a bandaid so fix the real problem rather than creating others.

so is the buzzing caused by the amplifier or the headunit?
because using a bandaid (ground loop isolator) to try and 'cover up' the original problem, isnt the best way to go about it - you should actually identify and fix the original problem
i would suggest removing the GLI and then going through and checking/re-doing all the wiring and grounds in particular

wirese are seperate sides of car,
noise is all the time not just engine whine
all grounds are paint free and good
amplifier was previously perfect when using another cd player.
another amp was tested and still buzzing occured but not as bad.
believe me when i say we have spent alot of time on this.. i know pioneer rca outs are weak and blow interanal fuses or whatnot but this shoudlnt have anything to do with my current problem?
all i have done is replaced a tape deck with a cd player (NEW)

sounds like a faulty cd player - why not send it away for testing/repair as opposed to spending money on a GLI which only gives u a different problem?

yes i should, it is a us model that i purcahsed.
just seems weird that gli is the aparant cause of this problem...
i do nto understand how it can affect fading?

hmm...I would ditch the GLI and borrow a headunit to plug in.
Then you'll be able to find the real source of the original problem.

noise on a Pioneer head unit is caused (in most cases) by the ground fuse on the RCA's having blown.
thinking of replacing the fuse, not like the normal fuse most people are use to?
as long as you can see a 1mm x 2mm SMD on the PCB and know where to look for it and have the correct equipment its easy, if not send it off to Pioneer service and have it checked over. as has been stated, ground loop isolators are just a nasty bandaid fix...
another thing, what car, what amp and what RCA's you using?

do you know what a shorting plug is?

firstly, what brand isolator did you use?
If you get phasing problems with it in (but not with it out) then the isolator is faulty.
if you have noise all the time, then you have a problem, likely caused by a faulty RCA lead, or faulty head unit.

get any old RCA that is stuffed and cut the RCA plug off the end, not too close to the end.
strip the shield down till both wires inside are exposed.
twist them together and tape up. remove your RCA's going into the amp and turn on the system.
if there is no noise in the system push in the RCA you just made into one of the inputs and listen for noise.
try all channels and see if you get noise from all of them or they are all quiet.
just remember to remove your ground loop isolators before you do this...
this test will tell you if your amp is noisy or the noise in induced before the amp i.e. RCA cables or head unit.
see how you go
