amplifier whine

[Guy88]

Just got the 6x9's and me subs rigged in the MK6 but got a couple of problems

Its got a verv bad alternator whine, whats the best gadget to stop this, iv checked all the earths and there good

Also with the volume on 0 i get a rumble and the odd bang from the sub and 6x9's, what would cause this, i get it engine on or engine off but its only thru the amplified speakers

Any ideas people, sound qualitys spot on apart from the above

Its a pioneer head unit, nikkai amp,twin mutant subs and vibe 6x9's, premium cables and gold plated rca's one set for sum and 1 set for full range

did you run the power cable along side the speaker cables?

[skiddy75]

i am with u on the power cables thing if running rca leads are they well insulated

[Guy88]

RCA's are completley away from power leads, the amp is behind the drivers seat and the batteries are under the seat, RCA's run along the floor and up the passenger side step and a pillar across the dash to the stereo

[skiddy75]

have u tried a inline surpressor ?

[skiddy75]

u say batteries does that mean u have 2 if so u may have a magnetic field which is affecting the amp directly

[Guy88]

not tried and supressors

Yes i have twin battereis, but even with the amp a good meter away the noises are still there

[skiddy75]

try surpressors on the constant live to amp and the switched live as close to amp as poss and see how it goes

i had the same problem with my amp and it later turned out that it was my amp that was the problem( i blew the amp but it still worked just made a lot of noise when it was on)

You need a 'ground loop isolator' Guy

I agree, used to get loads of problems on XR2i's but never had a problem with anything else

[Guy88]

right, il get an isolator, cheers rover

This is the only vehicle that this set up has been bad in

Also now i got thumping thru the 6x9's all the time, About 1 per second and you can see the speakers moving

[Guy88]

fitted the ground loop isolators, thumpings gone but it still whines like f**k

[rover]

You got a problem then mate, I've fitted loads of isolators to get rid of whine, usually on diesels too.

Is the suppressor conected on the back of the alternator? or is it built in on the Mk6?
