I Will Buy The Sound System

Friends, I want to go myself and get the sound system from mediamarkt. Outside, because there are a lot of price differences, as you know, the prices are expensive, so I want to buy it myself.

There is a sound system on the vehicle right now, but the front companents are roadstar and after a while sizzle, the sound becomes poor quality. The amplifier was something like soundmax, I think it's a cheap brand made in the market. I am pleased with the sound in the rear doors, although they are not connected to the amphitheater hertz. woofer gives the kicker 30cm quality bass but i find it insufficient.

Now I want to change the companents and the amp and I want to get an extra woofer. and I want to connect the hertz on the back doors to the amplifier. Can you offer me high quality amps, bass and companent.

but get something to lift the front companent, rear speaker and 2 woofers. So how many channel amps do I need?

How can I fit 2 woofers in the rear trunk?

how much will they cost?

It is not connected to the amplifier in the back doors. It is called the coaxial speaker. If you want to connect to the amplifier, you should also purchase them. If you are going to use it, you should use two different amps. One strereo 4-channel amp, which will feed only the compenants, and the other 2-channel mono-amp that will only feed the bass.

I understood, thank you, but I did not understand the two amps, because some of them have 2 bass. 6 channels are those amps? Reviews
