    In the documentation, you will find a chm file with a section called speaker setup.
    You should use the 4.1 and make the wiring for the sub from the front or rear output.

    ok i got a 3.5 mm splitter and used the front channel to feed my front ch amp & the subs. It worked good, but the fronts now seem to have a lower volume. is this normal.

    Does splitting the audio signal reduce volume???

    Thanks a lot for the help guys. I was really going nuts.

    You're right the picture don't show the sub but on the official cable one is labeled for the sub. Anyway, using the front channel is a good solution.
    I think that it is normal that the level is lower using a splitter, the energy should be splitted.

    yeah, i found out that those home speaker systems have a built it splitter in the sub box. that's why you don't need a dedicated input for the subs. Unfortunately, this is not the case with car audio systems.

    Anyways, its running fine now. I just have to fix my gains, as the subs are bumpin so hard now, i can't hear my highs.

    Thanks guys for the help, and if you have any other comments or ideas, keep this thraed alive

    I have one more question.
    I want to get a cap, where do i wire it. I have a distribution block feeding power to:
    4 Ch amp for speakers
    2 ch amp for subs
    carpc
    inverter for PS2

    what's best. Shall i put it before the distribution block for everything, or just before the subs amp.

    I know that caps release a huge amount of power in msecs, so is it bad for the carpc and inverter.

    I think pradecki can help here as you have one in your setup.

    well i suppose it depends on the size of the cap and what you want it to do.. capacitors are wired in parrallel w/ your battery so you could put it anywhere in the line, however depending on what size power calbe you have off of the distro block you will determine some locations you might not want it.

    the main thing is that you get one big enough to support the draw it will take. depending on the actual amps your system is drawing i would probably recommend a 2 farad cap given 2 amps plus a power inverter. In my car I have a good battery so I wasn't as worried about the sub amp drawing too much power, I was more worried about the voltage dropping for the lead on the power inverter and my comp shutting down because of it. thus i wired it right before the pwoer inverter. however your best bet is probably before the distrubution block. The reason being that if you start your car up w/ your inverter on you will need the cap to provide it power as the voltage drops momentarily, also you will probably want power for your sub amp when you are bumping some tunes w/ the bass cranked. typcially your wire conencting your amp and inverter to the distribution block is smaller than the wire connecting the distro block to the battery. Thus putting a cap after the distro block might cause too much amperage to flow therough the smaller guage wire if different components are simultaneously drawing power from it. hence putting it before the block should reduce this chance of wire damage/fuse blowing and provide power to whatever component needs it.

    as far as your thought about the cap releasing too many amps don't worry. a battery can release hundreds of amps, think what happens when you start your car, but I can also connect a 12v flashlight lightbulb to the electrodes on a car batttery and run the light bulb as long as it would last in its original flashlight. amps are not a force like volts. only as many amps as needed are drawn from a cap or battery. so a cap acts as a backup resevoir when your battery can't supply the needed power quickly enough. Thus caps are designed to release power in msec (the flash on any camera is powered by a cap being discharged for example), if your battery voltage drops too low momentarily your power inverter/comp/amps will draw whatever power it needs from the cap until either the battery voltage rises backup or your cap looses all of its charge.

    Also a cap will help prevent wear on your alternator. I blew my original stock 100 amp alt in my car because I had no cap and an average battery. when i replaced it i upgraded it to a 160 amp alternator and recently added the cap for more protection. each time your sub hits hard and the battery can't supply the power quick enough, you headlights dim, as they dim extra power is drawn directly from the alternator which causes accelerated wear on the alternator

    Sounds like you need to do a search about upgrading the BIG 3!!!
