im looking into getting a subwoofer and an amp. i want good sound quality, but good SPL at the same time. ive heard alot about elemental designs. i was looking at the nine.1 and the 13Kv2 subwoofer combo. would i be dissapointed with this if i bought it? or are there better options out there. i will have around 350 to spend between the amp, the sub, and the wiring kit.
