Use a test light or Multimeter to verify that you have at least 12volts on your remote wire as well as your Power cable.

I have a linear amp 1600 I ahve power to it but it wont work and what is the remote wire supose to be connected to?


The remote wire is supposed to be connected to the remote output on the back of the head unit that is feeding the amp.
Without the remote wire hook up the amp will not turn on.
Reason for this is, the Head Unit tells the AMP to turn on, without the remote connected the AMP is going to do nothing, find the remote switch wire on the back of your Head Unit and run the wire to the remote input on the AMP.

Ultra Linear UL600HC gain pot broken off of board


No, open the system, check the switch in questions, get a soldering iron and desolderer to remove the switch, do it carefully, when you have the switch in your hand go to maplins or somewhere like it, find an exact replacement(wont be hard to do) and get someone confident with a soldering iron to solder it back in.

Power light on the amp goes on after 5 sec off ultra linear 1200


If you run the remote from the battery you will need a on/off switch. Sounds like the amp is overheating. Also, I don't understand bridge the remote and power. They should be seperate going into the amp.

Ultra linear ul-600hc


If the amp is in protect mode, it probably has shorted output transistors. To eliminate other possible problems, do the following. I'll assume that you've checked the amplifier's on-board fuses.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

If the voltage remains near or above 12v, disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp almost certainly has shorted output transistors and will need to be repaired.

Let me know if you have any other questions.

Whats is the perfect amp?


I have 2 of these 12" running in a Large slot ported box with an:
"Ultra Linear UL2402"
600RMS X 2 @ 4Ohm (Stereo) 1200RMS X 2 @ 2Ohm (Stereo) 2400RMS X 1 @ 2Ohm (Mono)
Can be run in Tri-mode with 3 8Ohm subs, which these subs are. I have not tried this mode. This is
600RMS X 2 @ 4Ohm = Max RMS of your subs. You should run the max of your subs, less wear on the amp you are using , and i doubt you will ever need to turn it up far before it blows out your trunk or window :P
1200RMS X 2 @ 2Ohm = Blown Subs!
Has 4 x 25amp fuses, most will tell you this only has an RMS of around 845, an "ultra linear circuit" produces twice the output power over Modern amps.
Can had on Ebay for around $100. I bought mine for $101.
This Amp pounds, i could quickly tell a difference going from 300RMS X 2 @ 4Ohm with a Kenwood amp. I Had to turn all my settings down on the new amp to have a better balance in sound.

Tune the gain on your amplifier powering the sub. Turn the Bass Gain on the amp all the way down and crank up your system to as loud as you can stand. Adjust the bass Gain until the Speaker begins to distort, then back off a little bit. This way you can crank it up and not get Bass Distortion early.
