I wouldn't waste my time on any of the I-Force lines from Zapco. The amps are the only ones they make that are built in Asia. Not that an amp is inherently bad if it's manufactured overseas, but it's the ONLY amp they make that is. Not really Zapco, if you follow.
The Zapco CK-16.2 (competition line) don't test well at all, but are top notch and nailed a subjective score of 80/100. That is, the flaws aren't audible in a vehicle environment. (FYI, DLS 6.3 don't really "test" well either, but they sound fantastic).
Pelon you as/sface, you guess they would be good? Way to help out. Who says that!!! Why do you even bother posting that s/hit on a BB. Your feelings towards a speaker you never even listened to are WORTHLESS. Did you hear me, cause if you didn't you as a member here are worthless. Go away, no one want to read about what you haven't listened to!
