No sound from stereo?

I just installed a amp and sub into a friends 98 Sunfire, and after I reconnected the battery, the stereo wont make any sound. What could be the problem?

thanks

Be more specific list all the equipment and how you connected things

The amp was a Rampage 240 watt, hooked up to a Roadmaster bass tube. I spliced into the rear speaker wires to hook up the amp. ran a power wire from the battery, and hooked upa power REM from the fuse in the fuse block for the radio.

Did you use a high to low converter to tap into the rear speakers and then go to rca. Also dose your remote wire turn on and off with the car. And when you say you get no sound do you get absolutely no sound from any speaker? And I assume you are using the factory radio and what model and year is the car?

sorry did not see your last line year/model

It's a 1998 Pontiac Sunfire with a factory HU. I used the high input with just the wires. And there is absolutely no sound coming out of any of the speakers.

Have you tried to disconnect the high input from the amp and see if you get sound? Also check all the fuses both in the cabin and under the hood.

"The amp was a Rampage 240 watt, hooked up to a Roadmaster bass tube. I spliced into the rear speaker wires to hook up the amp. ran a power wire from the battery, and hooked upa power REM from the fuse in the fuse block for the radio."
So if all you did was tap the rear speaker wires then you should still have sound comming from the front and rear speakers.Sounds as if your not telling us something?????From your post your telling us all you were doing is powering up just a Roadmaster bass tube.
You got me lost.

I've told you every thing i've done to it. Unless i forgot(which I haven't) something, thats everything i know.

We unhooked the battery and it has the "Theft Loc" but it never asked for the code to restart it.

If that helps anything.............

Make sure that when you hooked up the line out converter you didn't accidently short out any of the factory speaker wires (i.e. they aren't touching any bare metal and there's no exposed sections of wire).  I know it sounds unlikely but a lot of times when there is power to a radio but absolutely no sound output, it's because of a shorted speaker wire.  This causes the radio's amp to go into protect mode until the short is fixed.

esmith69 he didn’t use a LOC he used the high input on his amp

Sorry thinking of another post he must have used a LOC. SO disconnect the line out converter from your rear speaker and see if you get sound

Sounds to me like you may have (hopefully not) fried your radio when you hooked up that basstube to the rear channel. Most stock head units don't have a lot of leaway on impedance and max load that can be put on them. Most stock rear 6 X 9's channels can't handle any more than a 4 ohm load and adding that basstube probably put you way over that. Maybe I'm way off but as soon as you turned the power back on, the power supply in your head unit may have melted. I hope this is not the case and that it's just a blown fuse.

Clarification to my last post--I meant to say the radio is still powering up, it just has no sound output.
