Audio setup advice

No i bailed on it and got someone who knows what they're doing

[Sonic]

Sub box all complete. I've not wired the amp's in yet, that's for tomorrow. Can't wait to see how the subs sound!!

Still got my mb Quarts ( bought 2 yrs ago )sitting in their boxi n the garage, maybe they'll go in the Avant

[Sonic]

The subs are in, sounding awesome

As expected, they have some serious kick and a nice sharp response with tracey music

One thing i can't quite work out though, there is a crackling / popping sound from all 4 speakers, not the subs from what i can hear, but only when the engine is running.

The crackling also increases with more engine load, not speed or revs.

Put some more screws in the box mate, i have my screws 30mm C-C

[lind4hl]

Otherwise, it looks real good and i bet it sounds nice also!

Its got about 70 screws in total, along with internal braces and silicon sealed. Its pretty sturdy

It sounds really punchy, and having the other amp on the front and rear speakers is a massive difference to running them off the head unit.

I think i need another battery though

Just need to solve the cracking / popping sounds and fit the Neutrik connectors when they arrive so everything is removable easily. The 2 vibe connectors work well for the amps, i just need some more 8AWG cable to finish them.

batteries, as usual, booring money to spend..

Check the ground on the power amp. You might need to move it to a different place.

Will give it a go, cheers.

I've got -ve for both amps running to a screw in the left corner, which looks like it has something to do with the light cluster.

I've taken some wire wool to it and it was causing a problem for the subwoofer amp previously, hence the wire wool.

Are there any better ground points a the rear?

[lind4hl]

ground on the battery

[Sonic]

Is that good to do, i'd heard otherwise?

[lind4hl]

i have done it on all my amps, and so have my mate´s, no problems at all,

i have the Orion d5000 amp. (5000W+ max)

my mate´s got:

2x mutant xxx 1500.2 (1500w max each, measuered to 1760w on each)
Dd z2 (10000W max)

No problems with electrics in any ways, so i would say go for it!

Edit: of course amp model doesnt change anything, but i just said it since it good to know that they are high quality amps and also big ones that put some pressure on the "powerbank"

Ill clean up the existing ground and see what different it makes first.

The -ve from the speaker amp joins onto the -ve from the sub amp, so that might cause a few noise issues also.

Failing that, i'll go straight to the battery and see how it sounds then.

In the ABY coupe the battery can't be any further from the mounting screw i've used anyway

huh?

Edit: aha, you´re talking about chassis ground, thought you talked about speaker connections first, it´s just me that are tired..

That shouldnt be a problem really, ground as ground, as long as it´s Bare metal against bare metal
