Will 9 volts hurt an amplifier with rca inputs rated at 4 volts? do you just lower the gain on the amps? the amps are alpine 50 watts x 4 channels.

This will not hurt the amplifier. The output voltage is not a full time constant 9v.

does this come with as bass knob

No, but you can adjust the signal level going into your subs from this crossover.

中高音はいいが

低音域がサブウーハーとミッドウーハーのモノラルになるのでDSPにすぐ買い換えました仕様をよく見ないといけなかったがクロスオーバーとしては問題ないのでミッドウーハーもステレオ出力になってれば完璧でした
