first , i want to thankx one of my youtuber friend ,
’’ krannyman92 ’’ for the assistance he gave me.
he sent the plan to make this box , btw , the best
and easy box i ever built !
second : i blow the pioneer 1000w. rms ,
third : the kicker cvr , 400 w rms passed the test ,
but i paid attention , the amplifier is 2000 w rms ,
fourth : the rockford fosgate sub at 1000 w rms
passed the test , and the surround was better than
the last time .
