yea i usually hate ragging on people who ask questions but he is 100% correct.....if u go with the 2 subs just use 1 sub because its 400 wrms supposedly on the amp and both subs are 400 wrms each.......leave the cvr....mayb get another cvr and get a better amp....then u should notice a difference....those 25 dolla subs are shittyyou got what you paid for.
