Re: delay

10 to 20 minutes? that sounds like a internal problem in the amp. I have never heard of a amp taking that long to start up, there is definatly a problem in the pre amp stage of the amplifier.

I got a sony xm-460gtx amp I hooked it up in my truck everything was working fine then I disconnected the battery and reconnected it now there's power to the amp but no sound out of the amp???

If you are getting power the amp lights will be on k so I would check your coax cables and all hook ups to the amp. on some radios there is a sub control that will turn on your sub and to adjust your bass mine does the same thing when i disconnect power to the radio.

How do I hook up a sub woofer to my 52wx4 radio. I

You can hook it up a couple of ways.
Depending on how many subs you have and what ohms they are running at here is the chart you need. If your going to run one sub off it the last option is the way to go. Your going to need to find out the power of your subs or else the power could be off and you could blow the sub. If the rms power is higher than 130watts per coil you will be fine. If so there are four channels on the amp and two should show a line going to each other that says bridge. Hook up the positives and the negative of the subs as shown on the amp that will get your max power. If your sub is running at 4 ohm. Let me know, if not thats how you would do it.
Also for the power and remote wires. Hook up a power wire (16 gauge would be plenty fine) from the battery to the + terminal of the amp. Then take an equal or bigger sized wire from the - side of the amp and secure it to any medal part of the body of the car. If there is paint on it get if off. (not on the outside of your car or where any water would be.) Then run a remote wire from your stereo (most the times it is blue and white) to the remote terminal of the amp. This tell the amp when to turn on and off. Your amp will not turn on with out all of these wires. Good luck to you and let me know how it works out.

    Um the power light will flash then the protl. light will flash its all hooked up right but weird sounds coming out my subs.

    Disconnect subs from output of amplifier and then turn on car and radio. Does amp stay on or go into protect? If it stays on then there is something wrong with the subs or how they are wired (series, parallel ) to the box and amp. If it still goes into protect then something internal with amp.

    the easiest thing to do is check the voltage at the amp, between the red power wire and the black it should be the same as the voltage across your battery under the hood. now turn your radio on and c heck the remote turn on wire this wire is at the amp and is usually blue it should have 12 volt when the radio is on and 0 volts whe the radio is turned off check between the blue remote wire and the black ground wire unhook subs from amp and check the resistance across the speaker terminals with a digital mutimeter, if your subs are 4 ohms then your reading on the meter should be around 4, if it is close to 1 or 0, then it's probibly your subs. if everything is good check the fuse on the amp

    Unwanted bass coming out of my subs

    there has to be sumthn hooked up wrong bc i have had same problem with my 12' subs but it was simply a matter of my rca jacks but sense you have checked them try rewiring the speakers if that does not work then your rca module may be burned out within the amp..iso then check the amp by taking the cover off and making sure nuthn is burned on the inside.or if any wires are loose or touching.

    KAC-9102d no sound, Amp powers on but no sound to the subs.

    If the sub isn't working, you won't get a pop. All you need is a small speaker. Don't need a sub, you just want to test the sound. I recently blew 2 subs, no smoke, no smell, no sign of being blown. Absolutely nothing from the subs.... In the past my sub locked up. You can take your sub out of the box and hook the + and - to the battery to see if you can get the sub to pop there. I believe a small box will push a sub into a deep excursion to the center of the cone. I have 2 lanzar VW12D's that just quit. I hooked a 6 x 9 up to my amp and low and behold I had sound! Try that and see what you get...
