custom 1997 pontiac firebird sub box and amp rack. i decided to build my box and post pics. the amp rack is also made by me. i work at lowes in the lumber dept. so i picked up our oak birch plywood for $5 for a 4x8 sheet in good condition. just was cut into 2x4 pieces and the customer decided not to buy. i have to say the install came out perfect, and it looks great in person. as if a real professional built it. im 19. and me and my dad made this in about 6-7 hours. i wrapped the boxes myself and he helped me put them together. not bad for only my 5th box build. i have to give credit to the person that created the design of the sub box that i made. it helped me alot. he posted a tutorial on this thread. thanks man. besides all the builds on this site are amazing and helped inspire me to come up with something of my own. and the final install............

i just wanted to hear opinions and find out which of the subs were better. i heard the momos 15s and they sounded good and were extremely under powered. its just BOGO subs right now thru crutchfield.com and i wanted to sell my system and upgrade.

where they 12's or 15's?

right now i have a decent setup which contains. (2) rockford fosgate 450.4 amps (puts out 225 rms to ea. sub when bridged) click here (2) mtx Jackhammers (400 rms) 6x9 Kenwood Speakers (125 rms) i plan on selling my mtx subs and upgrading to (2) 15 inch subs. i want louder sound. higher lows. and an overall higher spl. correct if im wrong but i believe 15 inch subs are louder then 12 in subs. so heres my question. since CRUTCHFIELD has a BOGO on their subs. i plan on buying ethier the rockford fosgate 15 in sub (200 rms) click here or polk momo 15 in sub. i can buy dual voice coil or single voice coil.(400 rms) click here price is the same so that doesnt matter. just want in honest open. also i will be making my own box so if you could give me the pros and cons of sealed versus ported that would help. i added hyperlinks above. just give me your honest opinion. i dont plan on upgrading my amps any time soon. (just bought them) thanks for your time.
