Stereo/alarm draing car battery

[mark3871]

Ok this is a mess and don't know where to start. My son got stuff installed at two different shops.

1. 2003 Honda Accord

2. Got viper alarm with remote start installed

(week later)

3. Got touch screen headunit and two amps installed (one for subs1000w other for the four inside speakers 600watts)

4. about a week later car needs jumped to start. something is draining the battery. My Neighbor said its a 6 something drain on the battery with key out.

5. stereo, amps and alarm all on same fuse. if we pull the fuse then car alarm is deactivated. Should all this be on same fuse?

where do we start to find the problem? any advise would be greatly appreciated. should we take the car back to shop that installed the alarm first are start with the stereo shop or what?

i it is 6 amps most likely not the viper...........but while doing the drain test unplug the viper all harnesses then retest.....if its still there then take the fuse out of the power wire for the sound system still there then its a problem with the car.......

viper brain will be under the driver dash roughly 3x6 inches...

if there is a capacitor or second battery that is most likely the cause of the draw.
