    Speakers

    I bought these because they were thin and the only thing that would fit. They sound amazing and handle the power great without distorting. I am very happy with them. Pair them with a sub woofer.

    Installed 2 pairs of these bad boys in my 21 accord along with some kicker tweeters and man ohh man it’s the sound I’ve been missing and looking for!!! And I haven’t even amplified them yet which they’re known for getting the best sound from.
