vw mk4 monson amp and another amp
well what happened is i did not know that vw where so stupid to not have a remote turn on, on the monsoon amp... and I had wired the whole car up only to find this out at the end and after reading and reading found out that if 5v is appled to the left (-) negative(common) channel it turns the amp on... the problem is that i had another amp wired already and was to lazy to remove it and just us the vw amp and also did not want to cut the other amp out as is seems to be more of a crossover then really a amp and too cheap to buy crossovers in it's place... so when 5v was appled to the left (-) common channel the other amp, being a store bought amp has a overload protection on it and would go into protection.... well to fix this i built a little circuit that would allow me to pass ac and block the dc from going back into the amp....
2- 1000uF 35V electroletic caps
1- 10k ohm resistor
1- 7805 or any 5 v voltage regulator
if you put the two 1000uF caps with the negative together then one of the postive sides is the input for the left (-)and the other is the output for the left (-) creating a dc filter... then on the output put the 5v output of the regulator together then with the resistor put it from the gnd of the regulator to the output of the cap as well. then just tie the lefts (+) together and hook the gnd of the regulator to the gnd of the amp and the Vn of the regulator to the remote turnon of the second amp...
this is really hard to explane in text if somebody needs help just ask i can try to explane again in a different way.
output | input
| 12v input>---------------------|7805|
sorry that is the hardest diargam to draw with keyboard chars.
the only problem is there is a bit of gnd noise when the computer boots right now and goes away once computer is booted i will have to filter out that gnd noise but thats later.
