why

have you seen the pics of the amp? it has 1 set of power terminals.

there are still ways go get more wire connected.

i read that stetsom and various others can get away with using one set of power and ground terminals on their like 6000-7000rms amps because the runs will be so short the wire wont have any resistance to it or something sciency like that. people who use them have battery banks in the back right next to the amps as to make the run from the batteries to the amps as short as possible.

yes my batterie bank is right next to my amp

Double check your resistances with a DMM.

You could have something wired incorrectly or maybe a shorted or dropped coil? I would just verify that the impedance on the amp really is 1 ohm or higher-

i dont really have anything to add on top of what is already said add more wire and check your wiring over again/DMM

i just have this to add show some pics of your setup i'd like to see a build log

explain me how to test that i have a dmm but i dont kno how to check that but still even i disconect the speaker wire the protect light stay on

If you disconnect the power and it stays on check the remote wire. You may not have enough voltage going to the amp.

the wire getting hot sounds like a bad ground some were . ground it to the frame directly. batts too. now for the light? i have no clue.

to set your gains,

set your DMM to measure AC voltage (between 1.0-40.0v).

Set everything on your amp to 0 or as far down as they go.

disconnect your sub from the amp, play a 50 hz test tone recorded at 0 db.

test the voltage of the amp while this tone is playing (put the DMM probes in the speaker terminals)

You need the voltage to be = to or close to:

the ## of watts you want to put out DIVIDED by your sub's ohm load

Take that number and square root it.

This is the number you want your amp's output voltage to be at.

Once you have your gain set, play a test tone (recorded at 0db) of where you want your subsonic filter to be at. While playing, raise your subsonic filter until your amp's output voltage is affected (starts to lower).

To set your highpass, play the tone you want your highpass to be set at, and lower your highpass until the voltage is affected (lowers).

Old thread is old.

I don't get how these get bumped back up.

I dont get why he explained how to set the power by DMM, when the power isnt the problem....
