Yeah... Not so fast..
Let me torque your gourd for a bit. As I posted I'm running a set of 2ohm infinity kappas in the rear. The RMS (and I use this term loosley) are about 110w. My amp is rated to about 150w @ 2ohm and 100w @4ohm. I'm pleased with the sound I'm getting however when I push the amp I realize some distorion, (thats if I really push it). I'm running the majority of my music through an
mp3 player so it's very compressed. If I bump my gains up to where I get the bass I'm looking for it's just a little to much for the kappas but if I turn it down a bit I loose to much base (on some songs) and find myself re-adjusting. (Maybe I'm looking for too much) Regardless, the kappas are only designed for so much. We're talking a pretty fine line here.
My choices seem to be:
add another pair of kappas in series bumping the ohms up to 4 and cutting my wattage in half but creating more head room, Or... adding a pair of subs.
Now when I say add subs I'm not talking about 10s or 12s, I'm thinking 8s, more of a mid bass. The thing is installations in a cars and boats create so many variables and without knowing what everything is going to sound like before I cut holes takes a lot of thought.
I've used a little extra time to experiment. I've tried some baffling with fiberglass behind my kappas in the the bulkhead with marginal results. (it's a little better though) Many people wouldn't notice the difference I'm looking for but I do, and like an old friend once said, "If your stereo sounds good to you, its a good stereo." So, I continue contemplating.
I'll likely go with these subs.:

Any thoughts?
