i have a 05 ford focus hatchback. Their are 2 speakers in the two front doors. I know that for the price, i would be getting low end speakers. I am not an expert at speakers and which is better, and when i read reviews it confuses me. I just want to be able to listen to music at any volume and have it be clear, crisp, but have the ability to change it to the music i listen to. I was told i would need an amp to make it sound better? Any advice would be great. I don't want to spend a ton of money too. Thanks!
