As far as the stereo being connected directly to the battery, this is done to maintain the memory, clock setting, etc. The draw from a stereo is very small, so it will not drain the battery under normal circumstances.

Raul, I'm not trying to start a fight, but my factory installed stereo/FM/AM/CD/DVD player would take my trailer battery to a "dead" state within a month and a half, if I was not hooked to shore power.
The current draw on these things can be on the order of 0.05 Amps, in the "standby state", and yes, it does not sound like much. But, in 24 hours, this equates to 1.2 Amps . In 30 days, the battery has lost 36 Amps. In another 15 days, the total draw has gone up to 54 Amps.
I may be wrong, but I seem to recall that a 55 Amp reduction in the charge state gives you a dead 12 V battery.
I installed the inline on/off switch Rich mentioned to completely remove its parasitic draw and have had no further problems. And, I have not missed the memory settings it was trying to save.
