New setup opinions, Help me get lower and louder

[Rodeo91]

I currently have an e15a in a 3.6 cube box tuned to 29 hz, run off a lanzar 1200-2c in my Isuzu Rodeo. I assume the sub is getting roughly 600-700 watts rms. This setup gets fairly loud and pretty **** low too. I want to get even lower and louder, you know that fluttery bass that makes you want to puke .

I was thinking of getting a RESX 18 plus a bx1500d, ported of course, tuned low. I also wouldnt mind doing a dual sub setup, only can't be too expensive. I'm looking to spend no more that around 400 for subs, and no more than 400 for an amp. I have about 36-37 inches side to side, and 18 inches from floor to the top of my backseat. What do you guys suggest I run to achieve this in my next setup?

try re tuniing ur box to around the mid 30s, should notice a loud difference

why not an 18" XXX? it would only about 450 and just get a cheaper amp like hifonics.

only 700 watts? that e15a is laughing at you. double the power, and see what difference that makes. if you want to keep the same sub...

if you don't, an 18 would do exactly what you want - get louder and lower...but the box will be a lot bigger as well

where in NC are you, btw...?

I don't really want to tune any higher because I love the low bass that this box has, I just want it louder, and even lower . I was considering the XXX18, but I'm not sure if I want to fork over the cash. Is it worth it?

I am in the Raleigh area.

i vote on 18" SX. should sound better than the18" XXX would with 1500 watts.

well see, the e15a isn't necessarily for low bass but sq instead. dont get me wrong, it can go for it but re woofers can go lower. id say get the xxx in a decent sized box and like someone else said, hifonics amp is excellent for the price to be had.
