5.1 dramas

[skits]

Hi all ...im pretty new to this so please bare with me and ill try to explain my problem My setup is:

Clarion vrx815 lcd HU

Clarion DVS9775z DVD mp3 etc player ..this is also the dolby prossesor

Clarion apx600.5 5 channel amp 75w x 4 and 190w x1

front speakers: focal polyglass series 2 way splits 165v slims

rear speakers: focal 2 way 165ca access series

centre speaker: clarion srk601 with its own 25 w amp

Sub: pioneer 600w sub

I had this whole system proffesionally installed here in Aust about 4 months ago and have had nothing but drama ... first 1 of the front 2 way splits mid bass started making loud cracks and slowly got worse and was distorting badly and then stopped working... the back one on the same side also was making wierd noises but not cracking just fuzzy and distorted ...this was at any volume ... now the centre one is hissing during certain music. I went back to the installer and basically he didnt want to know about it ...thats another drama for another day ..I pulled the speakers out and took them to a repair place who tested them and said they r fine...so now im looking at the wiring myself ..The amp appears to be setup as 2 channels high pass 2 chanels band pass plus sub and the wiring appears well done and grounded properly etc ..

I pulled the crossovers out for the front speakers and the input appears to come from the amp and the output tweeter wire goes to the tweeter but the mid woofer wiring seems to head back to the brain (not totall sure without pulling seats etc out) and the mid woofer was on the original factory speaker wire .

Does this mean the front speakers are driven off the HU and if so why does the input to the crossover come from the amp and all 5 channels on the amp are used. .basically this whole system is so F***ed up and has never sounded right and my lack of knowledge hasnt helped ... It cost me a truckload of money to get installed and the mob who done it dont want to know me now and just piss me off... Sorry for the lame explantion but any help would be appreciated as to what the speaker wiring setup is... can i just wire the mid woofer to the output of the crossover and ignore where ever the hell the output goes to now..

Thanks

well th distortion and crackling that started on the front speaker sounds a lot like clipping. clipping occurs when the amp is pushed to hard and it cannot put out enough power for the speaker and instead on a sine wave it starts to create a straight DC type signal. This is very bad for the amp and especially the speaker. If you had all the speakers including the middle speaker tested and still cannot get it to work i would say plug a speaker into each of the 5 channels of the amp 1 at a time just to ensure they are all working.

See if you can pull up the wiring diagram for the crossovers so you can figure out exactly what wire are going where. Worst comes to worse go back and have the installer check out his wiring to make sure it is all still intact, because if all the speakers work and you test alll the channels on the amp the problem most likely lies in he wiring. If you have tested all else there is probably a short some where down the line.

Like i said it is a drama to go back to the installers...this mob screwed me due to me being ignorant with a pocket full of cash and i live 600 miles from the city where it was installed...serves me right really but i did expect the system to be functional ...cut a long story short they stuffed me around on 3 different occasions after a 8 hour drive and on the 4th it turned to **** and i ended up pulling the idiots phone out the wall and him calling the cops etc so its not an option going back to them ... in US dollars i was charged $1200 for the install alone and the whole system cost around $7000 and its just an exspensive digital clock in the dash now... I ran a seperate wire from the mid bass crossover output to the mid bass and it seemed ok ...i just dont know why the existing wire would head bush and the factory wire is hooked to the mid bass driver ..its just a f***ing drama
