ohhh bahi amplifier is good , atleast power rating are true
look at fuse
all you need to have concentration on wiring
Donot go for d4
go for d2 307 or d2 308
i suggest you , 308d2
after looking 308`s parameter ,
308 is more efficient then 307d2
again , if you donot change ur wiring later on , u will damage ur stuff , it can be 7150ub as well
