I assume a series of amplifiers with one F/B The F/B is the portion of voltage/current F/B from input to output no matter how many amplifiers are in series within the loop or what the gain of each one is.
An ordinary amplifier can have high gain but is unstable, drifts, can oscillate, etc. An amplifier with negative feedback has lower gain but is stable, does not drift, won't oscillate, etc.
The series input resistor and the feedback resistor.
unregulated voltage minus series regulator transistor drop.
Voltage drop due to the resistance present in the series circuit causes voltage split over a series circuit.
The main Difference between Voltage and Current Feedback Amplifiers is in the sampled(Output) signals. In Voltage feedback the sampled signal is voltage (Vf=Beta*Vo) where Vo is the sampled signal and for current feedback it is current signal (Vf=Beta*Io).

current series feedback amplifier=series parallel feedback amplifier or voltage to current amplifier,or TRANS CONDUCTANCE AMPLIFIER.
The series input resistor and the feedback resistor.
The current series feedback is a negative feedback in which the output current feeds back a proportional voltage back to the input terminals in series with the input signal. Here the output impedance as well as the input impedance increases as both are connected in series.
Here it is the current sampler and it is connected in series. while the voltage mixer connected in series.
this series do not need any other external voltage regulating devices
output resistance decreases and input resistance increases
In a Voltage Shunt feedback Amplifier, the feedback signal voltage is given to base of transistor in shunt through a feedback resistor.This Shunt connection decreases the input input impedance and voltage feedback decreases the output impedance. In this amplifier input is current and output is voltage. Thus Transresistance is stabilized.Input and Output impedances are reduced by a factor of 'D'(desensitivity factor). Advantages: 1)Gain independent of device parameters. 2)Bandwidth increases. 3)Noise and non-Linear distortion decrease. 4)Prevents Loading effect. 5)Acts as good source for the next stage.
Car amplifiers can be as loud as those which have more than 1000 watt power. The Loudest TL-1021 series from WIKIO are some of the loud car amplifiers. Audio Assault also comes out with car amplifiers of 1000 W.
RBC-1 is for JX, Slash and older A and G series amplifiers, HD-RLC is for the new XD, M(Xd marine, and HD amplifiers. The cost is the same of $29 for both of them.
