I hooked up my amp and everything is turned on and correctly hooked. the only problem is that when i connect the speaker wires the sub will not come on. i checked the sub on another set up and it is working fine. please tell me what may be my problem
1. Did you witness this amp ever working if not then you may have a blown amp. Hook up the speakers, get a portable player with a head phone jack get one of those cables with a headphone plug on one end and RCA's on the other plug the portable player into the amp and hit play. If sound comes out then your problems are elsewhere. If not I'm afraid your amp is probably toast. If the OHM rating of the speakers are too low for the amp then the amp will go into protect. This will be indicated by the protect LED lighting up or the power led changing color from say green to red.

Is the amp switching on? There are two 12v wires that have to be connected. One from a direct constant 12v supply source, and the other one from the ignition switch 12v source.Find a single 12v. supply which you can take from the lighter connection and then trace a 12v wire that runs from your ignition switch. This is mentioned in the amp manual.Double check. If the amp is coming on but no sound, then your wire connections from the amp are not correct.Or you have also connected the speaker wires incorrectly.Remmember not to connect the earth of the speaker wires to the direct earth(body of the car) but to the earth wires that are shown in the manual as this could blow the amp power IC. The earth wires of the speakers are marked -- and + respectfully and are also colour coded.You should have a RCA female plug connector from your amp to the subs. Check everything double and if still no luck their is a possibility that you could have blown an IC in the amp from wrongly connected wires. Hope this is not the case.
have you got the auto ariel lead from the head unit connected to the remote connection on your amp? if not then that is your problem, it turns the power on when you turn on the unit. and turns it off when you switch unit off.
you mean that the SUBWOOFERS connected to the amp cuts off and come back on randomly?? did you bring the SUBS level to a high volume ? i suggest to check first the value of the speaker (ex. 4 , 8 , 16 ohms ) matches the same value with the amp . second , hows the subs connected , in series ? or parallel . you will need a multimeter for this task .
here is a short test you can try, remove the rca audio cable from the amp & connect a diskman or toher audio o/p device that you can hook up with the same rca wires, turn on the amp & see if you have sound. you can also remove the speaker wires from the sub & using multi meter read the ohm's of the sub, most subs are 4 ohm. Hope this help locate your problem
