Advice appreciated
I have a 2019 equinox LT and would like to improve my sound quality and volume range. I don't really want components ideally I'm looking for full range speakers. I love driving with the windows down but when I crank the volume the sound quality tanks. I'm heavy into classic rock and the blues but I listen to everything really. Not sure what materials would be best with this type of music or if that really matters here? I've browsed Crutchfield to check what fits my car but am clueless to the rest lol. If I only upgrade my front and rear door speakers will that be sufficient for what I'm trying to achieve? Don't need the whole car vibrating a ton lol it already does that with stock speakers. Any recommendations on good quality brands or maybe what I should look for specifically is appreciated. Thanks in advance yall!
