which ones would give me better output? going to in either sealed or ported, most likely ported, box. full power going to subs. (buying an amp to match) im looking to hit more then 130db as that is what im hitting now with two p2 12". im going with 4 15" because of the looks, and these are not expensive at all. links are here RFP4815-https://www.woofersetc.com/index.cfm?fuseaction=product.display&Product_ID=2264 PW1577X-https://www.gooddeals18.com/product/PW1577X thanks for the help guys.

honestly, i can't beleive you're even asking about the pyramid. the fosgates aren't going to be much better than the p2's you already have, as far as power handling and quality. remember, it's much easier to blow a sub in a vented box than a sealed box. so to answer your question, go with the fosgates. but, IMO, you could take all that money and buy one good quality sub that can probably out do all of those. ------------- Whatever you do, DO NOT let the white smoke leak out of the wires.....

Um...Pyramid is about the lowest quality you can get..I'd rather buy a radioshack sub than that

lol, i figured that you would say that about the pyramids. the rockfords look alot nicer also so i was leaning for those. four of the 15" rockfords would be about the same as my 2 p2's? hmm and you said that i could go buy one nice subwoofer for the combined price of these, any suggestions? im looking for somthing that has a good xmax so it moves alot lol. again im kinda going for looks also so any help would be great. thanks

Oh four of those Rockford 15's would destroy your current two 12 inch P2's

well, a good vented box, tuned to around 35Hz, will definately push them to the max.

Um...use WinISD. It has an excursion graph..you just enter how many watts your pushing to them and it'll tell you the excursion at what frequencies
