Sound Dropout

[Ad_N]

The stereo has been in the car a while now, and all of a sudden I have noticed that there is a sound dropout. It happens every now and then and is beginning to piss me off. I will start the car, and it sounds as if there is only sound coming from the rear speakers. It may take 5 minutes or half an hour and eventually the system goes back to normal.

The system comprises of components in the front and 6 x 9's in the rear run by an Audison amp, and two subs in the boot run by a cadence amp. I had pretty much the same system in the old skyline and I have disconnected and reconnected cables but to no avail.

Any ideas anyone?

yeah... new cables...

if not that, then a new headunit or amp...

its hard to diagnose this problem without having a look at it... got anymore info for us?

i'd back the amps matie .. whatever is powering your front splits is having issues ... orrrr I know its a weird idea but your cones have dust one them .. check!! sounds weird but can seriously stop ur doof going doof .. has to be only about 1mm thick

also check your head unit .. see if wiggling the wires which connect to the h.u turns on the speakers.. then u might find ur problem

Head unit is brand new. Cabling is all in good condition. I was thinking perhaps a loose earth.

didnt you say in the first post that you disconnected and reconnected the cables?

well that includes earth cables... so if you have already done that, then i would suggest no... again...

but if you haven't done that, i would suggest going over your wires... again... for the first time...

is it a sudden pop and theyre working again? cause if it is, its a wire somewhere... or whatever amp is running them is going into protect when you turn the car on, then waiting to come out of it...

most likely cause of a LOOSE WIRE...

Dont get emotional. I did say I checked all the cables. Not the wires eg earth. Again... dont get emotional.

you make me cry

wires/cables... they're the same thing...

again... you make me cry :'(

Wires and cables being the same thing could be argued. Anyways, I'm only shit stirring hey. When I checked all the wiring/cables, I was referring to mainly RCA's and cables to the amps, speaker cables and head unit cables. As far as I can find there is an earth cable which runs from the head unit, and as the two amps are connected I think there is one earth from them.

As I never installed the system, I should probably just go to my installer but I was hoping to try and figure it out myself.

ive come accross problems where the power of the battery would sometimes cut out the sub for a while etc.

POSSIBLY a new battery dont take my word on it, as DRD-00F said, hard to tell untill you see/test it.

[DECIM8]

NEW AMP God damn u boy lol

How old is the system all together then its all new?

Doof doof knows more than me .. but my system is way better hahahah

[DRD-00F]

psh, your boot install is better... thats about it i think STILL haven't met you...

but yeah, its a weird problem... if it is just popping back on instantly, then its either a loose wire or the amp is in protect, cause of a loose wire... Wish i could have a look at it, but im betting its one of those... dont think its your gear...

that ground running from the head unit you speak of is the remote wire for the amps... it tells them to turn and off... its a constant positive feed, dont know how strong, but if its exposed somewhere and hitting the body of the car, then it will turn the amps on and off intermittenly...

DECIM8: Im thinking about dropping 2k on subs this weekend... you STILL gunna have a better system then me then?

[DECIM8]

Hahah 2 K on subs .. wasting it .. I got my Fusion NV comp series for $300 and it shakes buildings apart... Not to mention my poor boot..

Wait im a lier .. Unless your dumping it on some JL series or somthing? Id love to hear that .. W7

I hope you got some serious front setup to match .. I wanna install those crazy lil vibrating things... Haha just for the chiqs bro hahahah

My boot install is crap im going to rip it out and start again for the 3rd time .. to hard to please

I wanna see ur install!

check your fuse coming off your battery that goes to the amp... they wont looked busted but 90% sure its f**ked.

Replace it you'll be suprised.

EDIT: or your amp is going into protection mode for lack of power/earth

[DECIM8]

If the fuse is gone it wouldnt turn on .. Ive blown one before hehe BOOOOOOOOOOOOOOOOOOOOOM BOOOM SHAKE THE ROOM

My install is what we in the profession call... "temporary"

i have some powerful MBQ for front, and some alpine Type S for the rear... i still need to amp them, but they will be getting 100WRMS each when i get my ass around to doing it...

theres nothing special about my install as of yet, im still thinking up a decent and original design... i have a few ideas, but space appears to be the biggest problem...

and no, its not JL... the subs im getting are rated at nearly twice the power output of the 12W7... and its not some gimmick either...

see the 'danger zone'? thats the comfort zone for these subs

PS: they cost $1k each... but im getting 40% off... no one who is serious about this pays shelf price

[Gazee]

yea thats right, if the fuse blows it wont turn on, i didn't say it was blown, when you test for condinuity on a FAULTY fuse, it has condinuity sometimes and sometimes its a broken circuit... i.e. his dropouts of sound

you must really love your bass to pop a fuse LOL

[DRD-00F]

i've popped a boot before... what does that mean?

[Gazee]

LOL

it meant your boot latch was screwed...

popped windows before? now thats sick.. lol

[DRD-00F]

not as of yet luckily

but with the addtion of 2500wrms subs and a 3kw amp... we will see

i actually buckled the boot on my old car... popped in and out like a jam lid

[Gazee]

LOL fair effort dude..

great avatar btw
