I know this isn’t custom for a 240 but it will fit it just fine.
Single 10" Thunderform box with built in amplifier. Built for 1995-1999 Dodge Plymouth Neon. Sounds good I have it in my 240sx hatch and it sounds fine. I have pics it’s pretty much curved to fit around a wheel well.
Looking for $120 obo.
