Subwoofers / Speakers

I was looking at buying this amp ROCKFORD FOSGATE POWER AMPLIFIER T20001BD and I was looking at getting a Fi 15" BL or BTL but didn't know which one to get. And also what features to get with them I have never used Fi or heard of them and I am very intersted in trying them. Or even 2 12" Fi for this amp $500 for subs or sub. I have 2006 HHR its a hatchback looking at going with a ported enclosurer. Thanks for the help

2 Fi BL15, 2 Fi Q15, 2 RE SXX15, 2 SSA ICON15. which subs will be best over all in a mid size suv?

Ok so installed them today, but it is quiet as hell. Will it get louder as the suspension breaks in? It is a D2 wired for 1 ohm.

hello to all. as some of u know, i was on here about 4 months ago looking for opinions on a sub. well i went with a 2011 kicker l7 15 in a 5cf ported box and i must say it was LOUDDDD. but then the SQ started getting to me. so i found a orion hcca 12.2 on my local craigslist for 375 or possible trades. i messaged him and long story short, we did a straight trade. my kicker zx1500.1 amp will not run at 1 ohm so im running the sub at 4ohms and the sub is laughing at the zx's 750watts at 4 ohms. so i need a amp thats stable at 1 ohms, atleast 1200watts (no more than 2000. stock electric here fellas) and no more than $375. fire away!!

Let me know what you think guys. I made these kicks about a month ago, which included about 5 layers of bondo due to pinholes after sanding :punch: but I think they turned out pretty good. Oh yeah, those are the 307's in the kicks.

Two 15 fi Qs w/ BP would they be able to handle a Sundown saz3000?

Ok well I had this all wrote and and stupid me closed the tab out when I was looking up some info. So I shall start again. Overview: Ok, I'm planning on getting back into audio (not that I left for long). My past installs have all been geared toward being the loudest possible. My new plan is to try and make my setup geared toward SQ. I'm thinking about doing a 3 way active front stage. I still planning a sub stage but that is not what I'm worried about. I'm just not real sure on how exactly to get my front stage up and running. Now that you have an idea on whats going on, on to some questions. I plan on piecing my front stage together instead of buying a "kit" o…

i am kind of a newbie and i was think of getting an 18 ssd fully load with a 1800 watt kenwood amp wired to 1 ohm @ roughly 1000 watts RMS. in a 6 cu. Ft. box tuned to 26 hz. do you think it would be louder then 3 cheap 12's

I am not going to continue to ask for details on crapcom about them, so I brought it over here. I have a soft spot in my heart for round solo barics of old. I want to know if the CVX's are the round solo's reborn. I understand they are up market from the L5's, Polecat has said they are the choice for sealed over L7s in SQ and output, and I believe at the moment he is building a install with them in his 'burb. So, anyone heard them?

Hey guys..im having a little trouble with my sub right now..right when i start the car up, everything is fine..but after a little while it seems like the sub gets quieter. Sometimes it will play normal for 5-10 mins, and sometimes it will only last for a minute of less. I have no idea what could be causing this. Anyone have an idea?

i know both of the subs i want are really good. i just dont know what subs i want yet. its either going to be between the ssa xcon 18s or the sundown 18s. im going for more spl then anything. which one would put up more numbers? this is what i plan on doing to my truck no matter what. i already have the entire cab sound deadened. i have 4 super big interstate batteries to power everything, big 3, dual alts. so which one would be the best option for me?

Im having some minor issues with my two Z 15's and i was wondering if i upgrade to a couple of btl 15's what will i gain/lose wit output and sound quality? Is it worth the extra $80?

TwistedChild420 is selling his PSI LMS ULTRA, I wanted to get you guys opinion on this, and let me know if this is worth 800$? ~86 Pounds, 4" 8 Layer Flatwind Coil,Triple Leads,5 Long Throw Spiders,Direct Connect 8 gauge wire,6" Carbon Fiber dustcap Thanks for your input. I think I would like to get this, but I just want hear other opinions on whether or not this is a good buy for 800?

if u strad 2 saz3500 can u run 3 xcon 18`s off them

Well im bored and im going to start a new job soon, so naturally i must start a new project... The Car Anyways i'd end up taking the back seats out, doing a fiberglass sealed enclosure, for the mags at a slant fireing back, and probably do some sort of compartment were the rear seats are for 2 extra batteries, along with w.e. else i need, i'll end up pulling the floor up in the back also, if i really wanted to im sure the is enough space to go ported or if i wanted im sure i can have all the subs fireing back instead of at a slant towards the back, I was thinking the new focal 3-way series for a front stage or the CDT ES 3-way's also I was thinking a 250a alt should be …

Got the 12" hellion installed earlier today. Thought would take around 3 to 4 hours. But ended up taking 7 hours for amp install, LOC, sub into box, and box into trunk, tuned a bit and all good. The installer seems very knowledgable and super chill dude. I feel bad that it took so long... I was there just hanging out and talking with him throughout the whole thing and paying attention to learn some. Will post more pics tomorrow hopefully after work. I was suprised about how long it took to get through the firewall with a grommet. I guess the new acura TLX are not easy to do. Also that the installer tapped into the power and ground wires for the LOC into the ampl…

I'm in the process of planning out another system for my car. I have a Hyundai XG300 with about 5 cubes max to work with. I already have Infinity Kappa Components in the front and rear currently only powered by the H.U. (Alpine CDA-9886). For the sub woofer i have an 18" Fi Audio Bl With all options in a 5cuft box tuned to about 32Hz being pushed with a Kicker ZX1500.1. I Have Knu Konceptz Kolossus 1/0 AWG wire for power/ground with a Red Top under the hood. I have a Rockford 360.2 acting as my current S.S.F. (was going to use it for 4channel but never got around to ordering one). Im planning on selling all of this except the door speakers and redesigning my sub woofer s…

which one will be the loudest in an optimal box

okay i currently have 2 15 inch mags on the way (first ones were smashed by fedex, but thanks to ben levine at www.showrides.net im getting new ones at no expense to me. his customer service is an 11/10!) i have a 1000/1 right now but i wont be able to afford another 1000/1 for a while. should i run 1 of them ported (3.75 28hz) or both sealed 3 cuft each. i will be building the box and making sure it is very sturdy. now if you think i should build one for 2 15s ported then jsut let me know. all comments appreciated. i had drawn up a plan as 8 cuft ported with 8 4 inch flared ports for 2 15s already so i could do that.... but what would you reccomend as enough port area fo…

I have a 03 Ford F-150. I have an Alpine hu, and an Audiobahn A460L amp that was powering a 8" RF XLC. Max budget is $200. Shoot me some suggestions....

I have a single Dcon 12 right now in a Starr mountain sound box tuned at 33hz (i know its not the box) and its on a Boston's acoustics gt2125 bridged for 400w but I got it tuned way down prob seeing a honest 200w if that and it has this buzzing noise right behind the dust cap almost like a rattle only on the higher notes (low notes you can't hear it) I have the lpf at 70hz I wonder if turning it down further will help but I've had it in two different boxes and its done the same way in each one and I can't seem to fig out what's going on It sounds as if I set a screw on top of the sub while it was playing.

I was at a car show for lexus vehicles today. I had a chance to listen to a members 1 jl w7 13 on a jl amp, i thi k it was a 1000/1. any way i just wanted to say that my 2 xcons blew away that w7 by far! of course my xcons were in a properly tuned and well built encloseure powered by a mmats 3000.5. i showed off the excons and once again i amazed everyone when they saw that it was only 2 10's doing all that damage. People were like what the f..k? Two 10's ? NO WAY! and im like, uhh hell ya it is, and opened the trunk and showed them off. I will never sell these bad boys, i love them soo much.

Does anyone know of any nice 6.5" coaxials (preferably the size that can fit into the oversized OEM openings)...i've been lookin and thought i'd ask about any nice coaxials u guys had experience with...

I see a lot of heavy subs or multiple sub boxes being used with double baffles. Is there really any pros or cons to that vs adding some bracing inside the box? I'd think it wouldn't matter much, but I can learn something new here every day!
