    In addition to the problem I'm having with my subwoofer right now there is one other thing that has been irritating me about my system.

    If I turn the input level on my amp up very much then I can hear a faint high pitch whistling sound coming from my system when I'm driving. The harder I accelerate the louder the sound becomes. If I turn the input down a bit the whistling sound goes away but then I can't really get the volume out of the system that I want.

    I'm really new to audio equipment so the only thing I've checked is to make sure all the connections that I have access to (my amp) are secure.

    Check your grounds and be sure that your power wire, remote turn on, and RCA's are not run near a source of EMF noise such as an electric motor or relay switch.

    adjust gains the proper way and then if its not loud enough for you, upgrade your amp. there is no way youhave your gains matched properly and mismatched gains is one of the quickest ways to noise.

    Gonna take it to the shop I got it installed at tomorrow and have them look at it along with my sub. Guess it's good their labor has a warranty.

    You realize it's only a screw, right? They have no way of determining whether I changed anything or not. Anyway, they replaced my sub for free today -- just turned down the input level to get rid of the whine.

    yah, i turn screws all day. and i can also tell when a car ive worked on has been fucked with.

    and turning down the "screw" to "get rid of the whine" is fucking bandaid x10.:ugh2:

    find the root of the problem and then fix it.

    kind of car?
    kind of equipment?
    location of equipment in car?


    the days of alternator whine after every install are over. equip is better. less susceptible (sp?) to noise, allowing shortcuts in the install. ive ran power next to rca down one side dozens of times and no noise.

    there is a dozen reasons you have noise. defective equip. bad ground. defective alternator. to many grounds in system causing a large ground potential which could lead to noise. blown micro fuse in radio (if newer pioneer). xover mounted too close to factory equip which induced the noise. etc etc etc
