friends 1 month ago, I wanted to have a small sound system and my budget was 1800 something. We entered a shop that makes a sound system etc. that a friend of mine knows. I told the man exactly how I wanted the sound system, I said I didn't want the sound to sizzle. The room is okay, I will do it. You just listen after you do it, and he said a little more. Then I saw which brands to wear. I suspect that I knew more or less the brands. I said why do you wear audiomax or roadstar? I will make quality sound from them. and when I say if you say the prices separately, it did not say it .. as far as I learned from the internet; roadstar companent 80tlhertz speaker 200 tlamfi 130 tl subwoofer 225tl cables 50 tl desekmontaj 100tl sayek705 is off, I gave 1000tl this is not a problem anyway, I guess we won't trust it because I think we know it. I guess they call the front door compenant.It installed the Roadstar brand team. kicker 30cm a subwoofer I do not know the details of it exactly. system in brief: roadstar compenent hertz rear door speaker + treble li.audiomax 4 channel 1600 watt amfikicker 30cm subwoofer and also i got kenwood multimedia player for 800 tl with touch bluetooth feature etc. My problem was that the sound came to me after I installed them that day because I did not know what kind of sound I expected, so I didn't have a car with a sound system before. I liked it when I say bass or something and I said okay problem, but today's complaint is something that a couple of friends say. the sound behind is better. The sound is very thin, except for the sizzling. The original speaker was better than the roadstar. I guess the speaker is insufficient according to the treble, although I made the treble adjustment from the equalizer -7 .. and another detail is the amphitheater of the front companents. They said they attached hertz to the tape on the back, but the sound on the back is clearer and of higher quality even though it is connected to the 'hertz' tape. If I tell you the sound now. bass is very good quality there is no problem there is not enough distortion in the back, but the sound in front is thin and it makes it sizzle when I raise the sound. Do you think we've stunned my roadstar speaker or doesn't it support the amp? If I buy another companent, does it support the amp? and I gave 1000 pounds to this sound system, do you think it is more? I'm so confused now that I don't know what to do. Would it be enough if I change the amp and companents or change the companent. Is there a companent that you can recommend to me that the sound that the amplifier can support will not be distorted.
