    5 channel or 4 channel + mono

    So I was curious as to what you guys thought would be better.

    I have an old school sony explode mobile ES 5 channel amp model xm-7557 rated at 4x100 and 280x1. I know newer explode stuff sucks but I remember these being pretty stout and like 700 bucks in like 2001.

    My question is is there any advantage to using separate amps for 4 channel and subs?

    The 5 channel has high current/high voltage select and has crossover's for each input individually.

    Also it has two input's for power and ground do I need to use both?

    TIA

    you would be running each amp at a higher wattage if you do them separately depending on amp/sub ohm impedance for example if your running a 2 channel amp maxed at 200wts and two subs they are running at ~100 wts each if you bridge one sub to that amp you get full power to the one sub.

      I would do a 4 channel and a mono amp or even a 2 channel for the fronts and just a mono for the subs. You dont really need to amp the rears.

        I HATE Sony Xplod stuff, BUT, the Mobile ES is actually good stuff. I'd run the 5 channel amp, you already have it, and you won't have to figure out another remote wire, ground, distribution block... and I'd amp your door and rear speakers, then add a sub and call it a day

          Yeah I can't think of why I would only amp the door speakers and not the rear.

          I'm only going to be running 1 sub. I have an old school rockford fosgate hx2 12"

          My thought was to only have one set of wiring, just wasn't sure if I would lose anything using one amp but I guess it's just built like that. Plus I guess stuff was made good back then. I wouldn't use sony car audio now to save my a**

            i think i kno witch am ur talkin about. when i 1st seen it i didnt even kno sony made something like that. older stuff is always better than the newer stuff. id keep that amp and make a built to spec box. if i ever came across an amp like that i would definitely buy it. if your not looking for somethin 2 loud this is the amp 2 go with

                Here is the link from the amp it was from 2001

                http://www.crutchfield.com/S-PiYM6JE...S-XM-7557.html

                As far as I know it was $800 brand new and worth every penny. I picked it up on craigslist for $50 fully expecting it not to work but it's been great.

                There is also a pic in my beginner ride's post http://www.cb7tuner.com/vbb/showthread.php?t=161503
