right now i have two 12in subs in a sealed box there pioneer premiere there rated at 1000w and are about 4 or 5 years old they still sound ok but i want more....i would like two 15's in a box in the back seat and would like to know what would be a good sub to go with...i have a 800 watt bridged rockford fostgate amp and its great..

 

i really only wanna spend around maybe $500 or less by the way

 

thats a good start for the subs and box. or a amp. but not all 3 unless they are used

 

i really wanna keep my amp lol and ebay is my friend right now haha

 

if your amp is a two channel you can go for a single 18" setup with a big box tuned to around 34hz or so

here are a few 18"

both are sold out but should be back in stock soon

 

Ok if i go with two 15's will this be a good box? http://cgi.ebay.com/DUAL-15-inch-SUB...3A1%7C294%3A50

and when you say tune what do you mean exactly

 

and how about this amp? http://cgi.ebay.com/NEW-4000-WATT-LA...3A1%7C294%3A50

or this one http://cgi.ebay.com/PYRAMID-4-CHANNE...3A2%7C294%3A50

 

Man.... With amp and subs, you have to match up all 3 of the components....The right amp for you sub and the right box for your sub...I could take 1 of you pioneer subs and build a vented enclosure tuned to whatever pioneer says for that sub and have it blow the 2 15"s you are wanting to get out of the water.....Buying a pre made box isnt really going to get you any where.....For example I built a enclosure for my buddy cobra for a single 8"(jl w3) that would put alot of people's 2 10"s to shame....


You have a model number of the rockford amp...

 

S.O.B Thats great...sorry its a kenwood amp not a rockford fostgate this is it http://www.epinions.com/review/pr-Ke...t_148067815044

 

Ok yeah... some its a 2 ch. not a ton of power and brigded it is only stable a 4 ohms.... The 2nd amp you are looking at(pyrmiad) is a 4 ch. it can work but I would go with something like a 2 ch or a mono....

I would first find the woofers you are going to want to use and then depending on their specs find an amp.
