Any pics...

no, my camera phone is broken at this point lol ill be sure to take some when i get it back though

I think you should have went for a more RMS wattage amp... as that amp will only push about 100W x 2 @ 2 ohms

No digi cam?

he's only running a P1 though, it's not a big wattage woofer. the P2002 is fine for that woofer.

yeah, i was going to get a JL 13' but it wouldnt fit in my car lol so i got two 12s i couldve got 2 jl10s but i got 12s since they would be better... if i decided to get some jl 12w7s and take the rockfords out my box could you recommend a amp to run it?

88supramki

if you went with a 12W7 you should definitly consider the 1000/1 and a COMPLETELY new enclosure for the woofer.

infa_red

why do i need to change the box?

88supramki

have you seen how big a 12W7 is compared to a P112?

infa_red

no,, but i figured it wud b the same since theyre both 12s

You have much to learn...


in this world not all subs are created equal

Infinity Kappas are too harsh for my tastes. They sure get loud though.

88supramki is right

each sub has its own requirements for space. you may blow the sub if box is too small or too big. if the box you have right now is not built to p1 specs you may not be getting the best quality bass from your sub or its full potential.

Robert_J

To expand on this subject, the space requirements are determined by the sub's Thiele-Small Parameters. Using these parameters and free modeling software like WinISD or Unibox, then you can determine the optimum box or a box that fits your frequency response requirements.

Not a true statement. The smaller the sealed box, the higher the mechanial power handling. That means it takes more power to reach max excursion. When pairing an amp to a sub (or even setting the gains), you have to look at both the thermal power handling (RMS) and max excursion (determined with complex math formulas or using the software above). Adire Audio gives a great example using their Brahma series subs - link.

it's true it requires more wattage on seald box ect... but if your box is too samall the air being produced from the sub can push out the sub beyond its limits when trying to hit the next freq ect.. sorry i don't really want to get all technical, all i am saying is to get full potetial get the right box for the right sub. seald, ported ect...
