1 12 or 2 10's

I have room for 2 10" subs in a 2 cubic box under my rear seat or I can put 1 12 in a small sealed box in the middle of the seat. Will the 10" subs sound better, or just louder. I know they will have more surface area but cannot hit as low as the 12's, any sugestions. I can spend about 300 on either 1 12+ s/h. or 300 on 2 10" subs + s/h. any sugestions. I have a 1995 chevy extended cab, kenwood excelon deck, kenwood excelon 5 1/4, kenwood excelon 6X9's, Kenwood excelon 811D to power the subs, 1 ohm=1000 watts, 2 ohm=800 watts.

thanks

What are you looking for out of the system.....

If you want loud..go with the 10"s and build a ported Enclosure to the specs of the subs....

If you want Sound quality go with the single 12" in a sealed Enclosure built to spec...

Thats just my advise..

Making the World A Louder Place

Thanks for the advice, I went down to our dealer, they deal in jl audio, alpine, kicker, eclips, planet audio, orion,phenix gold, and rockford. We tried everything it took me about 5 hours. I finally went with a rockford punch stage 3 2 +2 ohm wired at 1 ohm in a rockford slot ported enclosure. All I can say is o my god the base is so low and hard that it hurts. i am hitting 142db and thats no lie have all the mic paperwork to prove it. sound nothing like  I could have emagined.

Thanks to all
