| Hi everyone this is my first thread on this site and im not familliar with it so be indulgent please 
So this is my problem now,I have a terible noise problem in my car when I wire my component set to my 2 channel amp(new one).I ve tried 2 diffenerent set of stinger interconnects( the HPM and the bullets series) and nothing changes.So after a couple of verification about bad grounds connection I decided to wire my speakers to the head unit to avoid the problem but wtf,I still have a little noise in the speakers.Its not as bad as the one with the amp but its sucks.I went to future shop to ask a couple question to the installer and he said that it must be the head unit.What is your opinion on that?someone told me to puta another battery in my trunk to only power my sound system,is it a good idea even if I dont plan to break the 1500w?If it can give you any idea about my h/u its a 3 years old pioneer 7500mp.
Anyway im waiting for yours ideas. |

| Problem is the Pioneer and it's crappy circuit design. Nothing new, it has been a shat design for over 15 years.

| either get a new deck NOT PIONEER... id get a KENWOOD...
or go see a professional shop other than best buy or future shop... they SHOULD know what to do with the problem... I would suggest Car Audio Haven if you were close to Brampton, Ontario ... but you have better chances in Quebec

| Pioneer is a good line, they offer great value to the customer. It however has a inherant flaw in the design of the ground isolation circuity on the preamp section and this flaw has been there for over 15 years. You think they might have gone and fixed the design by now.....
Not all units are affected by it, I have had more than my share of them that have had zero noise related issues. A good install can quite often cure what ails you.

| There are several fixes... the easiest for most is a transformer on your RCAs or a choke on deck ground...
