I have a custom made ported box that a buddy built for me claims it would cost around 200 to buy all I kmow is that the bass slaps.
Sub was $600
Amp was $500
Box was $200
Easily have $1000 invested but need it gone to help buy a new car.
$400 bucks and it is all yours. Thanks
Dropped to $200 on 10/20/2025 because I'm an idiot. Call or text anytime. Thank you.
