Serious Amp Problem!

I will get to the point of problem..I have a Jensen 200 watt amp. I hooked up the 12 volt lead to battery with fuse of course. Used a 8 gauge wire. Amp has power now. I then hooked up lead to REM wire from Stereo to the amp. Car ignition on and Amp comes on, after i had already hooked up the 8 gauge ground wire...So Far so good!..Wrong!. I then used my test light on the positive speaker output on amp and they have juice going to them and thats not right. What is the problem? Can anyone help me out here. Whats causing this or did i wire something wrong at the stereo? :confused:

you are getting 12 votls DC out ofthe amp outputs ?
