So i just picked up my new amp its a ma audio HK802SX here is the specs on the amp

Digital LCD Display (Voltage, Temperature & Output Level) Platinum Plated Connections Quiet Fan Cooling System
2 x 500W RMS @ 4 Ohm Stereo
2 x 800W RMS @ 2 Ohm Stereo
2 x 1400W RMS @ 1 Ohm Stereo
2 x 2200W RMS @ 0.5 Ohm Stereo
1 x 4400W RMS @ 1 Ohm Bridged
Dimensions (H x W x L): 2.7"x 12.4"x 27.3"
and its one ohm stable as thats what im runnin it at right now through 2 mtx tens.

now im thinking of upgrading my drivers to either 2 15" or 18" subs and i was just wondering if anyone on here is running ma audio subs or heard them?

Do they sound good cause i found a good deal on 2 18" MA1800XL and i would like to match the subs with the same company as the amp.

here is the specs of the sub

800 watts RMS/1600 watts max power
Mounting depth: 8 7/8"
Mounting diameter: 16 11/16"
350 oz double stacked magnets
Reinforced, ribbed high-foam surround
Patented thermo-cooling motor structure
Copper clad aluminum dual 4 ohm voice coil
High-temp KAPTON voice coil

now my only concern is will this just be loud but sound like crap? i dont mind giving up some sq for more spl but im not tryin to build a pure spl machine i want a real loud daily pounder that i can still go to stereo comps with am i better off with 2 12" or 2 15" or maybe 1 15" or 18" plus my 2 10" mtx subs i just dont know how that would sound never heard a setup like that im guessing it would be hard to tune a setup like that.

Any feed back is appreciated and all this is going in a mk4 1999.5 vw jetta that im thinking of making a 3 seater i got a racing seat that i want to put in the center in the back and build a box that has a sub on each side of the seat.(i dont use my backseat really anyways)
