18" Fi SP4 setup help

btw why you recommending him sundown.. your suppose to help him out not set him up for failure, tell buddy to get some AA or Fi. i was gna get havoc 18s but changed my mind, going for 4 sp4 18s on 4 3500s.. ground pounder!!

 
yo cuddles, get your sp4 18 and make your whole trunk a box.. slap an aero port(s) and you will be golden. but now you gotta figure out where to put your batts and amp
I plan to try a lot of different brand eventually. I've been wanting to try Sundown. I'm going to give the Zv4s a chance.

 
your going with sundown? everyone on here are sundown nut huggers man, don't be a sheep. get a quality sub, those zv4s have less cone area than most 18s because of the surround, plus the zv4s are notorious for the surrounds coming undone

Get ur facts straight before u start spewing shiit. .the zv4 and x series surround were fixed after the first batch ..at least it wont catch on fire like a sp4.its not nuthugging jacob puts out quality products

 
ive never seen an sp4 catch fire, ive seen guys giving them 4k rms daily and havnt reconed once. im just saying, sundown isn't quite the way to go there are way better subs out theres for around the same price

Its not the company thats the wrong choice its cramming a 18 in the trunk just to say i got a 18..fi is a fine brand.i like alot of thier products but im not a fan of the sp4 if i were going the fi/ssa route id be finding a used btl or zcon or evil..im not in here to put down or praise a company ..i mean i still hate the sundown surrounds.....id be going with a single 15 or pair of 12s to get the most output from this setup

 
I beefy 15 is perfect and leaves plenty room for batts and amps. I personally would get a tantric hdd or shd. Mylows has a custom hdd 15 for a great price. If pink isnt your thing he can hook you up with new tantric sub.

 
Fi sp4's do great on the lows...i have a buddy ruuning 4 of em on an ampere 7.5 proto, they get down pretty low. CplCuddles, you could always take out your back seats, if you don't use em. Thats what im going to do in my Regal and run a single 18. What year is your MC?

 
I've actually settled on 2 12" Zv4s, gonna use a SAZ-5000D. Seems good to me //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

05, I am going with the Zv4s either way, I wanna give sundown a chance. Im not going to butcher my car. Trunk only and i can make 2 12s in a trunk work easily.
