So I've just bought some JBL MS62C's for the fronts, albeit secondhand I decided on these over the Focal PS130s in the end and am hopefully going for a Genesis Profile 4 to power them and the slimline sub in the spare wheel slot (JBL MS-10SD2). Objective is midbass and I've treated the doors with 2mm silent coat and 5mm CCF like so;






However I was wondering if this particular Genesis class A/B amp would provide enough power as its only rated at 55w per channel and the comps spec 80wrms and the sub at 250wrms (all at 4ohms). Will this be enough bang from the amp or should I look for something like say a JBL GTO 1004 or Audison SRX3 which is 100w per channel?

Also, after inspecting my inline fuse in my 4awg wiring kit there appears to be water damage so I'll need to replace it. What size fuse would be best for this set up? Was thinking around 100amp but am unsure

Cheers!

EDIT. The Genesis amp seller fell through so I've picked up an Audison SRX3 which hopefully will be ideal, thoughts and experience welcome of course.

 

100 amp fuse is probably fine for 4ga wires, but from the SRX3 manual it looks like the amp itself
has a 30 amp fuse, so in the interest of added safety I'd go with a fuse closer to 30 amps - 50?

 

I always aim for more headroom. You can adjust for too much power, you can't for too little.
