A bridgeable amplifier is a two channel amp where the two sections can be combined and used as a single channel amp with much higher (usually around double) power output.
There will be a switch or jumper that enables the bridge. Only one of the two inputs are used. The output is taken from the two positive terminals, one from each channel. The negative or common output terminals are not used.
A bridged amp fed from an electronic crossover is used a lot to feed a high-powered sub.
A bridgeable amplifier allows you to pipe sound across two discrete channels.
By bridging a sub it means that you are combining the power of two channels of your power amplifier into one, which then runs your sub. Not all power amplifiers are bridgeable though.
The Pioneer GM Monoblock Class D is bridgeable so it can be used for two or four channel stereos.You can also use it with multiple subwoofers if you want.
To power two 300 watt subwoofers, you will need an amplifier with a maximum power output of at least 600 watts. It is recommended to choose an amplifier with a slightly higher wattage rating to ensure that the subwoofers receive enough power for optimal performance.
depending on how many rms the sub is
The Blitz Audio Bridgeable MOSFET Power Amplifier with Lighted Blue Neon Accent Rods BZA2160 is perfect for what you're looking for. It's affordably priced, has plenty of power, and has stylish blue neon bars which will illuminate the area around the amp.
Depending on the RMS power of your sub, and size and brand of your sub, it will depend. If you have a single sub, I'd recommend a monoblock amp that puts out close to or enough to power your sub. You could also use a 2 channel bridgeable amp, as they are generally a much cheaper option. For dual subs, I'd say a bridgeable 4 channel amp, or high-output 2ch amp. To give an exact amp, I don't go past the Pioneer GM-d8500M 1200w Class-D Monoblock amp.

current series feedback amplifier=series parallel feedback amplifier or voltage to current amplifier,or TRANS CONDUCTANCE AMPLIFIER.
Selective amplifier is an RF amplifier which selects particular frequency and amplifier so it can operate at fixed frequency.
A voltage amplifier does not have to supply significant current bur a power amplifier does.
In audio look at an amplifier. It will be always a voltage amplifier.
