    6 speakers 4 channel amp? i'm lost!

    ok trying to wire up the amp. I got a 4 channel Sony XM-504Z Xpolde amp. and here is the cars layout. Pardon the very crude drawing =)



    Each door has 1 6x8 and a dual voice coil 8"sub. The rear deck has 2 6x8's total. How can i go about hooking this up? I am using the Audigy 2 ZS pci card if that makes any difference. HELPS ME hehe!

    thanks!

    also the 6x8 are pioneer TS-A6870R ( http://www.crutchfield.com/S-XgIc2WC...SA6870&g=52200 )

    the 8"subs are factory ford. they are dual voie coil and on the back they say 1.2ohms x 2 what ever the hell that means haha.

    yeah i have all the new speaker wire ran now and was gonna do like you said just put both front and back left 6x8's on one both front and back 6x8's right on the other then 1 channel each per sub. I just did not know if you could run 2 speakers (both lefts or rights) off one amp channel. I know nothing and i mean nothing about stero stuff =)

    Keep in mind that you said that the subs say 1.2 ohms x 2. Apparently dual voice coil which can yield either .6 ohms (run in parallel) or 2.4 ohms (run in series). Make sure whatever amp you get can handle a 2 ohm load for those speakers. You may want to research what kind of power handling they have too so you don't apply too much and blow them.

    The 6x8" speakers handle 50 watts a piece. With two hooked up per channel obviously that yields 100 watts. They are 4 ohm speakers which I would suggest running in parallel (each set: lefts together, rights together). This will give a 2 ohm load to the amp.

    So basically look for an amp that handles <=100 watts x 4 @ 2ohms. Be sure to find out if those factory subs can handle 100 watts RMS (not peak).

    dont know if this was mentioned but you should do this:

    A 2 or 4 channel amp for the 6x8's

    A monoblock amp for the subs

    If you tell me what kind of price range you have for the amps I will link you to some good amps that will fit your budget.

    As I read back I didn't realize that he hadn't settled on just using a 4 channel. You could also get a 5 channel amp. I doubt those subs handle tons of power, so an amp that could handle 50x4 @ 4 ohms (for the 6x8's) and say 100-200 watts x 1 @ 2 ohms would probably work out well. Also gives you the ability (if you have a 5.1 or better sound card) to adjust the levels of each speaker (including subs) indepedently.

    Yeah i dont think the subs handle much. they say 1.2 ohms x 2 and 60 watt x 2

    Cheapest solution (still much better than your sony amp):

    Viper 1100.5

    Quality solution:

    Elemental Design's NINe.4

    Elemental Design's NINe.2 (for the subs)
    http://edesignaudio.com/product.php?...pid=24&cur=USD

    There are tons of more options; I could spend all day throwing out different amp combinations...
