Should I do 2 T2 12's or 2 T2 15's

if you want to use the same subs you got on the power you already have, we can design you a box. usually in a hatch back, it is subs up port back. and those subs, I would chose the DBdrive subs because they match the RMS of your T1500-1BD amp. and with those subs, a 4 cubed box with plenty port area would be good. If you wanted help building it I can help and I also have four 4foot sono tube, each 7inches in diameter. which would be perfect for the fifteens. Then later down the road you can get better subs and amp and still use the same box.

you are correct, it said like 1840 I think @1ohm but as far power efficiency goes its a lot better than my hifonics brz 1700 and earthquake Ph-D10000 I had running before, not both at same time though. but if you guys have suggestions on good amps for a guy tryin not to spend a fortune let me know.

That's surprising. I mean I know fosgate it higher quality than hifonics but I figured the new hifonics lines would be just as efficient if not more. But I agree, just run what u have. Big 3 upgrade with an extra batt and plenty of good grounding, I think u will be ok. Just don't get gain happy.

I want to build a sealed box out of one of those tubes, or something similar. Would be dope.

I honestly didn't realize how much under-rated Fosgate amps were. A 1500 watt amp that puts out 1800? That's freakin awesome! IMO, the enclosure will probably decide the size speakers you should go with. The Power series sub don't require huge amounts of air space, but after displacements and port/ports, you may only have room for the 12's. Either way, you will be pleasantly surprised with the right box.

The 2500 puts out close to 3500. But they do **** some power.

I built a box that was about 4 cubes internal after port n all and I dont think it was that great, it was loud but not any louder than the P3's I had that were rated way less

Six cubes is really all they need? Is that internal after port size and displacement and bracing or before all thats factored in?
