whats wrong with pioneer? i had one 12" pioneer in my trunk and it hard and really deep. it sounded better than my bros rockford fosgate. he even admitted it. its all about how u set it up

 

12" SSD's from Fi Audio
Great subs for around $180 ea
Get a pair of Dual 1's wire the coils in series and then the subs in parallel to an mono 1500-2000w rms @ 1ohm amp.

OR

For more of an entry level sub that will require less strain on your electrical system the X series is great.

They are about $119 each
Rated at 250w rms so you only need a 500w rms amp to get loud and stay pretty clean. Just get the same D1 configuration for the pair and a 500w RMS @ 1ohm mono amp and you are golden.

There are other good companies out there that blow away the commercial products that you find in the stores and car shops. DC Audio, SSA, Incriminator Audio, ect...

 

Lets see Rockford fosgates power series, kicker makes a 13" sub. Orions hcca subs technically aren't 12 inch they are oversized so it puts them in the middle. Shall I continue?
