2003 kappa perfect 12.1d

Strengths:
Very nice desing and great Quality sound at recomended watage.

Weaknesses:
It can only handle 350w rms, plus you need to break it in at low-mid volumes for a long time before you can crank it up, other wise it will blow up.

Summary:
This is a very nice sub,looks great and souds good at the recomended power.Don't make the same mistake I did, hooked it up to a class D amplifier feeding it with 900w RMS at 2 omhs and burned it.You have to know the rigth impediance for each amp and sub.Remeber it is only 175w per coil.
