    How many RCA cables do I need?

    Ok gentlemen my HU only has two outputs (one red one white). I would like to install 2 speakers and one sub. I will be hooking up both speakers to a 4 channel amp that is bridged and the sub to a 4 channel amp that will also be bridged (but only to channels 1+2, channels 3+4 will not be used).

    My questions is, how many different RCA and Y cables will I be needing? Also, can someone post a diagram how all of this will be setup? I really appreciate it.

    Re: How many RCA cables do I need?

    lol buy a HU with more preouts

    You need as many sets(1red1white) of RCAs per 2 channels you use. i dont think u can ycable a ycable, need a converter or sumthing

    BTW thats 1 set of outputs man, u need one red one white for a single set

    The ALPINE CDE-9843 is working great so I really don't need to buy one just yet.

    not true josh,you can use the pre outs .be we need more info about the amp .look at the amp and see if it has a set of rca out puts or called a pass thru.if not then you need y connectors.but would be better sounding with a better deck.and dont use the sub out feature on the deck .

    You do if you want it done properly.

    Your best bet is a deck with front, rear and non fading sub outs. You can get cd players with these features for like 30-50 bucks. I bought my alpine off craigslist for 35.00.

    Re: How many RCA cables do I need?

    then u need a 2ch amp for ure highs or sub which ever. Thats 1 set of RCAs, the u can use that 4ch for ure other set, but ch1&2, thats 1 more set of RCAs

    Then buy these
    Monster Cable I101 XLN-Y-2F Y-Adapter RCA Interconnect Cable

    I dont see any other rca input expanders, with 1 set of rca outputs u can only double from what ive found

    Thats a good HU, just limited on outputs.

    Maybe someone else will chim in with a nifty gadget

    Could he ycable the at the amps then ycable another 2 amps together?(total of 3 ycables) That would allow the OP to use 3 sets of channels if he used the HP/LP features on the amps

    Re: How many RCA cables do I need?

    lol well theres the gadget i was speaking of, totaly didnt think of that.

    Just dont buy a crappy one, whats a good one even run?

    http://www.sonicelectronix.com/item_...e-CEQ-773.html


    If u had 2volt preouts, could a eq be used to gain 4v preouts? Would that really be of any advantage to the amps? my gains arnt that high

    Re: How many RCA cables do I need?

    OK rest of the setup:

    ARC AUDIO FD4150
    Hifonics zx 6400
    RAINBOW CS 265 PROFI VANADIUMs

    I plan on running the Rainbows on the ARC amp and the IDQ12V2 with the Hifonics amp.

    I do believe my hifonics amp has a pass through on it so I think I can just use a RCA cable (or two?) to connect both amps together?

    Here's what I'm thinking:

    Since the HU only has two outputs:

    One RCA cable from each output----> The RCA cable for the sub will have a Y cable at the end of it so I can hook it up to two channels.

    The other RCA cable from the HU will have a Y cable to hook up two other RCA cables for the two speakers, and both of those cables will have two Y cables to hook them both up to two channels.

    So, a total of 4 Y cables and 4 RCA cables?

    Re: How many RCA cables do I need?

    I have my old CDT 61as and IDQ12v2 running off the alpine HU, but they are connected to my hifonics amp, 1 channel for each speaker and two channels for the sub with a y cable. Maybe I am making this all too complicated. Do I just buy two Y cables and put each end at the end of the RCA cables coming out of each speaker and then just hook them up to two channels each? Seems like this would be the easiest thing.

    I use a Kicker KQ9 preamp in all my vehicles...the 5 will work just as well.You can find a decent one on ebay if you look,or you can but a 3ch x-over as well, but for adjustments at your fingertips...the preamp eq is perfect,and provides a better signal to your amps as well.

    the best and most important question is ,with all this nice equipment ,why are you running a hifonics amp with it?
