Who Knows What They Are Talking About When Putting SQ Into Car Audio?

honestly you wont find good sq midbass for that cheap. car audio is really defined by "you get what you pay for" if you want great sound quality you really should look into custom door panels with 10'' midbass and a set of 4'' components in there with them, and also doing your kicks like you said. one key thing is to not switch up brands/models of speakers because it can throw the sound off. key is doing the fronts to where they sound good and doing a mirrored image of what you did in the front, but in the rear. my suggestion would be to look at pioneer's new phase 4 line (i think its phase 4? or something dumb like that). its pretty pricey but well worth it. pioneer decks are also the best ive come across and ive had every brand from jvc to clarion to alpine to kenwood to you name it ive had it. seriously check out pioneer's new line tho its good ****. if you have the money tho hands down go with focal tho thats where true sq is at.
