damn, x2 kicker L5! must knock... I went from x2 12" rockford punch down to x1 12" JL w series. Now I went ported with x1 kicker L5 10" and it knocks!! mid/highs are MB quart component in the rear and pioneer 3way in the front. I would say just spend the few $$ extra for the alpine type r over the type s. But also look up a few other brands in terms of mid range speakers... O2, memphis audio, Ev. g/l with choice
