I need help with my amp, please =)

[Bassbustin]

Hey everyone, i have a general question about my amp and i was just wondering if someone could help me. i am running a single JL Audio 12W3V3-2Ohm sub with a boston acoustics gt 2125 amp and the amp is getting very hot. the suggested wattage for the w3v3-2 is 500 watt rms. i dont know if my amp is set up correctly for my sub...?

i see that there is a mono selection for the amp and they are the outside positive and negative selections and my sub is plugged in to them, i dont know if that is correct or not, should they be in mono? should i have them on the inside positive and negative selections or not? this is also a 2 channel amp that is bridgeable. i want to know how to bridge my amp to my one sub.

You're doing everything right. Those are the right inputs and everything, and it should be putting out 600w for the 2ohm load. Try turning the gain down a tad?

ok. i will try and turn the gain down a bit. i think its only at 60 right now.. i will play with it for a bit though. just wasnt sure about the whole mono and 1 ohm 2 ohm settings

so your sub is a dual 2 ohm sub ? or single 2 ohm .if dual you'll need to wire the sub as a 4 ohm sub if not you need another amp i believe

It's a single 2

ok so the amp will go 2 ohms bridged ,so either you have the gains to high ,bad ground ,or bad air circulation

I have the same amp it runs cool, check your grounds and set your gain correctly

If you are running highly on bass boost, or also have the Loud button on, will also increase the heating up of the amplifier.i dont use either..no need.Place 5-6 washers under ea of the mounting tabs to get that amp off the flat surface will help also to get a little air underneath
