I have 1 10" Rockford Fosgate XLC(not even the top of the rockford line) and it hits hard and even quite LOW. It only requires 200RMS and peek 400.I have a 50 x 2 bridged at 150 mono amp pushing it and it hits. The box is only under a qubic foot, with lots of trunk space to spare.. I can only imagine how 2 of them would sound. I do not plan to compete and could not see spending hundreds of dollars for thump in the trunk.... I am out of that stage. Back in the day I had my 2 JL 12's and a 400 watt PPI amp pushing the envelope of the decible decisive law enforcement department of POLICE......

Not only does the 1 10 sound great it is NOT an attention getter..Sound is very well contained to the car and not the neighbors(POLICE).Now for some, they like the attention.Not me I do not want any just great sound and awesome vibes....

Just my long 2 cents........

Good luck
