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 .
