that depends on the car and the brand of wires. you need to be more specific
The cost of car amplifiers is going to vary based on a number of things such as the brand, the car it will be going in, and what amplifier level is needed.
Normal car radio is no different than aftermarket. Determine the output wires on the radio, take them into the amp and the output from the amp back to the wires going to the speakers. Normal car speakers are not going to take the output of the amp if you raise it much.
This is not a very good amp, a better brand is recommended.

You can mount your car amplifier in the back floor or in the trunk.
In your 1993 Honda Accord, all the speaker wires typically connect to the car's factory amplifier or the head unit (stereo) located in the dashboard. The amplifier may be integrated into the stereo or could be a separate unit in the trunk, depending on the audio system configuration. If you’re upgrading or troubleshooting, ensure you trace the wires back to the correct component for proper connection.
Depends on the output of the amplifier.
Wires act as antenna always. In this case your antenna wire or the wires from your stereo to your amplifier are picking up interference from your alternator. You have an array set up because the different components of your system are grounded at different points. The way to rectify this situation is to run ground wires from any parts of your system to the same point in the car. Add wire to your amplifier, CD changer, eq and anything else and run them to the same point in the car. Put eye connectors on them ( ones with holes ) and put a self tapping screw through them all at the same point. Check behind that point to make sure you don't put the screw through a brake line or something. This should work. If it doesn't you may have to buy filters for your system.
No.
Yes. An amplifier can be added and intergrated into your system.
