Have you ever used a volume knob in your walkman it's a variable capacitor and it is connected serially and by the way walkman runs on battery means DC. the type of capacitor i am talking here about is just like a volume knob you increase the power it increases the speed of motor and this capacitor is connected through a power amplifier and this amplifier is as small as a matchstick but here in this Car case you dont need the anplifier if i am understanding it correctly then the pcb board of car is not producing full output to motor which is why the speed and power is somewhat less but by using this capacitor you can increase the speed and overall power of the car it stores the current from PC board and then produce the output to motor the current is 180 degree out of phase due to this the response time of remote or i can say PCB board would decrease but it will work.

Search for Electronis Schematics on google and youwill get the very best circuits for your project.
