need help choosign subs

i am looking at either purchasing 2 12 inch kicker l7s or 2  12 inch mtx thunder9500 for my 2 door chevy blazers are there any recommendations on which one to get or any other subs which i shoudl get i am also looking gfor ideas to replace the factory speakers i listen to mostly rap and someone told me it woudl be better for me to keep my factory head unit then to replace it is this true also thanks

I would go with the 9500's just because they have a little edge on the SQ side for daily listening,    I like L7's dont get me wrong but in a open cab for daily listening I dont know about how well that would sound2009 0-1000 Trunk WR 154.0DB 2009 1001+ Trunk WR

As far as keeping the factory head unit , thats up to you but since your asking , I would personaly swap it out no question. Most , not all , factory H/U just dont have the same quality output as most aftermarket units. This also depends on what you want to spend $$$ on the unit as they can start at $50 wal-mart to $2,000 for a Nakamitchi. Remember usually with car stereo gear , you get what you pay for. Keep that in mind if you decide to change out the factory deck. I believe you can get a much better quality sound and maybe even more features and options (bells and whistles) with a new deck.

The efficiency/sensitivity on those subs is a little too low for my liking. I don't recommend getting any Speakers/Drivers/Woofers/Subs that have a efficiency/sensitivity lower than 92Db 1w/1m. I would recommend anything from Cerwin Vega. I recommend looking at these sites: http://www.adelcom.net/CerwinVegaSSSubs.htm http://www.adelcom.net/CerwinVegaVSSubs.htm http://www.adelcom.net/CerwinVegaStealthBX.htm http://www.cerwinvega.com/products/mobileaudio/index.html

I would suggest that you go with 12" Sony P5's ! ^_^

That bit of advice......as it were......is that a joke or something?  You've eliminated just about every quality subwoofer and most other drivers.  Surely you typed it wrong.  The Adire Brahma 12 has a true efficiency rating of 84.1 1W/1m.  Are we to believe that it should be eliminated from our field of choices?

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

No, I did not miss type that. Lets put my 15in Cerwin Vega with a sensitivity of 98Db 1w/1m against your Adire Brahma with a 84.1Db 1w/1m and see which plays louder. For the fun of it, we would only feed them 32 watts. My cerwin Vega would be putting out approximately 113Db at 1m. The Adire Brahma would be putting out approximately 99.1Db at 1m. My Cerwin would be playing ~4 times as loud.

94legend.......How do they new Sony P5s sound compared to earlier models? I was never impressed with thier subs. 99 F-one fitty

So, I would be able to effectively power my sub by only using my Head Unit. Doesn't that sound good
