[HELP] Alpine SBE-1044br + ca-am-10900 1600w class D mono

I was about to buy Alpine Sbe-1044br and ca-am 1900600 1600w class d mono, for all that I'm going to pay 300euro ()

I just want to know if it's worth the money! If any of you have or had or know any who has, will you recommend ? It's good one?

I will have it in my vehicle (trunk) it's Audi A6 from 2000 (Sedan)

Please help me out!
