I followed the guides here on the forums on how to do a amp and sub install. Everything went well except the sub's max volume was extremely low, even lower than the stock hk subs. What could be the problem? My amp accepts high differential input, so I had that set and did not use a LOC. It also said in the 300/2 amp manual that 8 awg wire is the minimum power wire in bold letters and accepts 8-4 awg. So I used 4 awg. The wire was so big it had a problem connecting to the 40A Maxi Fuse, also recommended by the 300/2 amp guide. Is 4 awg wire too big or should I use a bigger fuse type. Thanks for the input. :thumbup:

Try the input sensitivity adjustment.
Larger power will not hurt a thing, smaller might.
If you had a hard time getting the fuse connected, you may have the incorrect fuse holder for the size wire you have.
Bad connections are not safe, they will generate heat and could cause damage.

I grounded the amp with 4 gauge wire, the same I used for the power. I believe the fuse box was the problem. I got the wrong Maxi Fuse that doesn't work for 4 gauge wire. I'll post an update when I install the new fuse.
