This is exactly the same issue i am facing in my car! so it is confirmed that this is some fault in alto! more over from my research this only appears in pioneer hi end pres!! if you connect the orignal jvc pre the sound will dissapear!! i had pioneer 9350sd and had to sale it coz this clipping sound was unbearable! now i am planning to buy pioneer 9450 but i am sure it would clipp too!!! another thing that i noticed apart from the ones that you are facing is that the sound is there only in usb or cd mode!! try aux the clipping would dissapear! is there any one who can solve this issue!! i went to pioneer service center they said its some pulse issue of the car!!
i have tried everythng!
1) grounding the rca
2) taking out the pre and connecting it directly with the batry with one speaker outside the car!! still the issue is there when the car is switched on
3) adding a filter at the back before the rca
so it is clear that its not the amp or the system wiring its something in the car!! i thnk suzuki knows it too because they fitted alto with JVC where as all other models had pioner at the time!! i am still searching for someone who can solve the issue! i have went to alot of electratians!!
okayy now the last thing that i found was to use resistance spark plugs!!! i have bot NGK resistance spark plugs (the ones that are fitted in the efi cultus! (available at suzuki))
NGK Resistor Spark Plugs - Each
i am plannin to get the spark plugs installed 2omoro and then get the pre!! i hope it solves the problem!!
PLEASE ANYYY ONE???? I HAVE BEEN FACING THIS ISSUE FOR 4 MONTHS NOW!! DID ANY ONE FACE THIS ISSUE IN THEIR ALTO?? PLZ helpp!!!
I went to hall road and the guy said that they had seen another alto with the same problem!! he sent me to CHABURJI to some electratain but unfortunatly i coundnt find the guy!!! I dont want to get any other pre other than pioneer!! soo guys!! all the experts!! come up with any thing??? any ideas??
i repeat there is nothing wrong with the pre or the amp or the wiring !! its something in the car!! i even connected a multi meter to check amperes and voltage both were stable!!!
i used the pre with a computer power supply
ups battry
and installed it in the other car that i have (cultus)
it worked fine!!! so the pre is fine
JVC Stock pre works fine
but pioneer wont
what is this!!! helpp!! plz!!
