    Icon9 Help Amp Monoblock Getting HOT

    Hi everybody.
    i want to ask some question

    my HU is pioneer DEH 24-UB
    my amp is monoblock pioneer GM-D8500M
    my subwoofer is pioneer TS-W309S4

    i use 4 AWG power cable and ground cable, 100A ANL Fuse , RCA cable from scosche
    but for connect from an amp to sub box,i use the RCA cable (i dont know what brand) and from box to subwoofer,i use the original cable that i got from subwoofer box .
    the subwoofer box is scosche 12",i bought in w**mart..


    gain setting is normal,LPF setting i didnt touch..
    so why my amp getting so hot?the amp still run even so hot..

    1.please see the word that i bold , is that the reason my amp getting so hot?

    2.should i use banana plug and 10 gauge wire from subwoofer to amplifier?

    3.if the problem is subwoofer wire,than i have question :

    the diagram now is like this

    AMP ----- subwoofer box ----- subwoofer

    now i want buy 10 gauge wire with banana plug and i put directly like this

    AMP ----- subwoofer

    can i do that?

    please help me to solve my problem master..
    thanks

    Re: Help Amp Monoblock Getting HOT

    u prolly didnt set your amp right. check it out how to set gains with dmm. Car Audio Reference Database
    did you say u used a rca wire as speaker wire inside the box for the sub? thats a no no get some 10 gauge or something as u have a small amp u could use 14 but the bigger the wire the better the flow but done go over board as again ur stuff is small.

    Re: Help Amp Monoblock Getting HOT

    so your suggestion is change the subwoofer wire system to amp with 10 gauge ?

    then step 2 is setting the amplifier gain ?

    yes 10 or 12 gauge , ur amp is very small so either one is fine. then set ur amp correctly

    What did you ground the amp to? Pics of install would help, too.
