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.

Sub system won't play can't find in settings amo hooked up to subs yet still nothin help plz


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.

My amp stays on but the sound cuts in and out. Some times it takes a good 20 minutes for the sound to start coming out after I turn my amp on. Also my sub sinks in right when I turn my amp on.


Check all connections and fuses. Also make sure your speaker can handle the wattage being put toward the speakers and the OHM load. Try a different amp to see if the same problem happens. Sub sinking in when power put to it means you may have crossed the connections Positive and negative to the speaker. Triple check that your connections are correct and your using the correct wire for the job.

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.

hope this helps

Can i hook up a powered 12'sub to a Pheonix Gold xs2500 amp without blowing the speaker


First I hope you remove the speaker wires from the speaker that come from the built in amplifire. You cannot hook the powered sub to the amp without doing that first. Then all you need to do is run speaker wire from the sub out of the box to the amp. In no way can you hook up any other part of the powered sub, but the sub itself, to the amp. If you know the wattage of the sub and the ohms then wire it to the amp correctly. Your phoenix amp will put out 125 watts x 2 at 4 ohms and 250 watts x 2 at 2 ohms and 500 watts x 1 at 4 ohms bridged. Remember, only the sub itself in the sub enclosure can be connected to the amp. Hope this helped you. Let me know if you need more help.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/mark_b53a7494531bf96d
