4 MTX or 4 He2’s?

I have a 94 honda accord... Right now Im running 2 mtx 6000's and 2 mtx 8000's off of a alpine v12 amp... I work at best buy so I get a lot of sh*t half off.. what subs hit harder the mtx or the He2's?? I am thinking about buying 2 rockford 2400w ( 800RMS) amps and running them to my mtx's but would it all hit harder with he2's??

I have had a single 12 he2 getting 750 watts rms and it lasted quite a long time with that much power going to it. It did really well for just one 12". I now have 2 12" Fosgate punch hx2's and they hit harder than my friends 2 15" MTX 8000's. That's not just me bragging, he was the one that said it to me first and I had to agree. I don't know how much discount you get there at Best Buy, but you can get some HX2's off Ebay for about $100 a piece.Pioneer DEH-P980BT, Zapco DCREF1000.4,Pioneer TS-C520PRS, Adire Extremis, MTX TA91002, TC Sounds TC-3000 15"

so you think it would be better to go with the Hx2's?? thats what my manager said too... would it be better with those amps I listed?? I get them for like 3 hundred a piece.. they retail for like 475.. so I can buy two for almost as much as Id buy 1 for... lol.. minus $125..... what kind of head unit should I go for if I get the Hx2's I want something thats going to push them... maybe sonemthign I could go to comp with ya know?? thakns for the advice!!
