when we connect the amp wire to the car battery we first remove the negative side then connect the amp wire to the negative side and reconnect the negative battery wire thing. is this correct?
there should be 3 main connections other than the speaker outputs. one goes to the battery + (through a proper fuse), one going to a good ground, and the remote turn-on from your head unit (this is what turns the amp on and off with the head unit.) if hooked up properly, it will not drain your battery.

Absolutely not! The amp power wire goes to battery POSITIVE. The amp ground should be as close to the amp as possible, and be securely screwed to bare metal on the vehicle frame or chassis. The battery negative should be removed while your are making the connections. The correct sequence is as follows: 1) Remove battery negative terminal. 2) Locate and mount the amp. Connect ground terminal to bare metal within 18-24 of the amp using the same gauge wire as the power wire. 3) Run power wire from battery positive to the amp power terminal. DO NOT install the fuse yet. 4) Connect remote wire, RCA inputs, and speaker and/or subwoofers. 5) Check that all terminals are tight and secure and that no strands of wire from one terminal are contacting adjacent wires or terminals. 6) Install the fuse in the positive wire. 7) Reconnect the negative battery terminal. The amp will not drain your battery when the vehicle is off. If the wiring is correct and the remote wire from your head unit operates properly, the amp will only turn on when the head unit is turned on.
