well its actually 18 p1 crossfire 10s on a ma4000 i built the box (his design not mine) but anyways he has very little money involved he only paid like 14 bucks for the 10s the amp was 200 and he got 6 used red tops for 35 each it actually meters a 151(term lab) legal with us sitting on the trunk and holding the fenders in. the car flexes like crazy it will do a hair trick (not some crazy one but it will do one) so dont hate on the guy cause he's trying something different.yes he could have went with some fi 18s (not knocking them i have 4 btls in my dodge) but when is the last time u seen 18 10s two amps and 6 redtops in the trunk of anything for less than 662 dollars
