Subwoofers / Speakers

What does inverting the subwoofer do for performance?? Is this completely cosmetic or does it do something differently than normally mounting the sub?? Also, How can you mount a sub backwards if the trim piece only fits on one way?? Is there a different trim piece needed to do this type of mounting?? Thanks everybody.

Just wanted some opinions on a good front stage for my 2000 grand marquis running 2 15" ssa xcons with crescendo 3500d. Currently using some cerwin vega HED365C 2 way component speakers up front not much mid bass at all an tried sound deadening the one door an still sounds not that great.

hi i am just wondering what amp i should get for a fi q 12 fully loaded which im going to order very soon. my choice so far: planet audio BB1400.1 ALSO ANOTHER THING WHEN I ORDER MY FI Q12 SHOULD I ORDER IT DUAL 1 OR DUAL 2, which would work best with the classD monoblock amp ? P.S. im a newb. thanks. -Patrick

Well, i was just wondering what kind of sub would be the best to get some spl out of a 1 cf box with maybe a little poly fil... Would have to be able to be powered off of a kicker zx750.1 and less than 7" mounting depth... Would like to keep it around 200 bucks but less would be nice and more may be doable but just post anything you think would be good... Sealed box of course and a 12"... Been looking at fi ssd, anything better than that output wise?

My new DC sound Labs 12" lvl 3 subs are on the way. I am going on a trip next friday so I hope to get them put in before then so we can pound em like they need to be pounded. Yeah yeah yeah

so, i just got alpine type s 6x9, and wow.... before, when bassy notes hit, it made a weird noise, but now its awesome! sounds super clear! so i wanna replace the rest, but i dont know what i want... should i go alpine all around? i dont wanna replace the 6x9s again, atleast anytime soon. i just wanna get rid of stock for now. later il upgrade to alot better everything. but right now, i think i wanna change the tweeters now. cuz they arent clear. theyre kinda.... not staticy, but like... its like theyre almost busted.i dont think they are, but it has that kinda... paper like sound. so i wanna do those next, then the door speakers, then my center dash speaker. any recommen…

Hey guy's let me start off by saying im new to the board, im in the crossfire of buying a mojo 15 or sundown zv4 15, don't really know which is the hardest hitting sub between the two. I have a ford focus se (trunk type) and im debating on doing a custom box in the trunk or inside the car and remove the backseat. So im asking for some help on which sub is the best and the best way to build the box. This will be a single 15" build BTW. I will be using an extra battery, 0 gauge wiring, 3500 amp. Thanks

My buddy wants me to put a system in his boat, and I'm looking for a sub any suggestions?

Well this weekend has been eventful. I was sure I wasn't going to have enough time to do all 3 and I was correct in my assumption. However, I took a giant stab at it and have took some pics along the way. I have been doing this a little at a time so if you have any advice then by all means. This is my first attempt at reconing any sub and I will be the first to tell you that if anyone uses as much glue as what came on these things then just let someone else do it if the price is negligible. It's different if the sub/motor is worth reconing to begin with, but what the hell I need to learn anyway right? So to start things off let's take a look at the culprits. Ok, s…

Ok I just got my Xcon 18 sub installed and am having a frustrating issue. At higher volumes and low tones the sub rattles! The moment I noticed it started I looking for the cause. I tried tightening the screws and adjusting the seal just in case there was an air leak and quickly figured out that was not the issue. I then thought maybe it was the box (a 6.5 cube ported box) but was able to conclude it was not. I then decided to push slightly with my thumb on the center of the dust cover while the sub was playing hard (and rattling) and the noise stopped. Is my dust cover loose? If not, what is the issue? The sub is brand new and literally just installed. It sounds so nasty…

Right there ... oh yeah. Will be running ~ 1000 watts. I'll make the enclosure fairly large - can always take away airspace if need be. It'll be sealed this time around (no way I'm going to try and figure out a port), question remains ... how big ? - Steve

well, i really really want two mj 18's in my trunk but the current box didnt fit! please help me out with a box design. the current dimensions for the box are 38 1/2 inch's wide, 24 3/4 deep, 24 1/4 tall. i just measured again and this is what i came up with...42 inch's wide max, 22 inch's tall max, and 21 inch's deep. please can anyone help me out. this is for my birthday presents which im going to be getting in two weeks. ssa i will be contacting you for two mj 18's really soon! btw i want the box to be ported...i dont care if its slot or aero. leaning more towards an spl box. thanks in advance

Will a icon sound good on 400 wrms? The box size is 1.45 cubic ft @ 40 hz

Been a long time out of the scene, so I'm trying to bring myself up to speed on stuff. I recently purchased a 1985 Cavalier convertible and the stereo has got to go! I'm not young anymore, married, kids, but won't settle for crap, so I'm looking mostly at SQ, but needs to be fairly loud since it's a convertible. The cavalier has an open area behind the center console, and I can fit an 8" behind there and tuck the enclosure under the dash on the passenger side. I think it'll be a fun/challenging project. Issue is, what 8" to go with?? It has to be sealed, small and handle up to 400w (Soundstream Continuum is 200w x 1 @ 4ohm). Was considering a Kicker Solobaric at fi…

Hey guys well im debating whether or not to get two fi bl or two audioque HDC 12's...the amp pushing them will be either a orion 2500D(both) or a DD M1(each)... They will be installed in a blowthrough enclosure in a 93 Nissan Xtra cab pickup...I was wondering which subs will sound better and get louder if that is possible...the enclosure will be 5 cubes tuned to 33 hz... thanks p.s. all opinions will be appreciated...

I am looking to replace my 2 12 kicker cvrs.I have narrowed it down to the dcons and the icon.I have 700 watts on tap from a bbl gto 700.1. I can't decide on a single 15 inch icon or two 12 inch dcons.which would get louder and still sound good

I have been looking around for a front end system now that I have my sub almost ordered. I know I need tweeters and other types of speakers to get this done. What do you guys recommend? I know there's 6 speakers total inside the car. My main questions are: 1) What brand and style of speakers 2) Is there a website I can look at for what size my speakers are? I have goggled around for a day with no luck... 3) I am (going to) use the SAX-50.4 amp. Would I want to use something different? This is just what was suggested to me. 4) Should I get a Component speaker? Or something different? I would like this to be pretty simple and not drawn out. What are you guys using? Did you …

just wondering what all people have heard about alumapro? has anyone used their subs in the past or present?

Hey everyone thanks for having me. So I am rebuilding my substage after blowing one of my ID 10s last week, which I had 2 of in a sealed enclosure with .6ft^3 each...and it was "lacking" to say the least. I have a 2005 F150 Supercab and I'm pretty limited to what I can put under the back seat. In getting back into car audio after over a decade, I am blown away by the kind of output todays subs are capable of, even from single driver systems. In talking to custom enclosure guys, it seems I'm pretty maxed out at around 2ft^3 which I'm thinking will be around 1.75ft^3 after port displacement (tuned into the low 30's) I'm looking for something that will have fairly signific…

i currently have a pair of polk db 6.5 components. the 6.5s dont go low enough, they are running on a power bass XAX2160FD 100rmsx2 @ 4ohms. i have been thinking about using the tweeters and the xover and installing a pair of peerless 830946 woofers. im not sure where the xover is actually set. but would this work? or what would you guys reccomend? i have a 15" ssd on 1300rms in the back on my tundra access cab. these would go in the doors btw.

I’m looking to build a ported enclosure for (6) Ampere Audio AA-2.5 6.5” D2 subs. They will be run on a 5k/1 ohm stable amp wired at a 1.33 ohm load. There will be plenty of power as they are 500 rms and 800 max. I can’t seem to get anything from Ampere Audio on the port size I need. With sub displacement my box needs to be 2.48 CF (+) port displacement. Does anyone have suggestions or know how to calculate the port size? Square inch and length is what’s needed. Hopefully someone can help on this

Hey guys , So , I bwew up one of my tweeters (playing with my x overs while at high volume , I know its stupid!) and since I'm changing I want to adress a annoying door-resonance I've got @ 2,5khz , I've had a peerless 830987 3inch fullrange paired with a 7inch before and I liked it , but I want better/more highs system consists of an Alpine 117r1 along with the h100 processor , an Becker energy400 4x100Wrms amp , AA havoc carbons mounted in the doors and in the back an AA SMD 18d2, 6.2cuft tuned to 27hz at the moment but tuning will change in near future. I've narrowed it down to : tweeters- I can get a pair of Hybrids L1pro pretty cheap I know of a pair of Pioneer TS-S…

what are you guys opinions on the RE XXX line of subs? are they worth the money or overrated? also, whats the smallest vented enclosure one of those XXX 15" subs can fit in tuned for 30 hz? what type of power is needed to push one?

I hear alot of people on here talking about the cone getting to hot, or warm, but how warm is safe and whats to warm? just curious thanks!

I'm looking into some new speakers for the rear spot in my ride (I have only stock as of now), although I have gone all kicker as far as the other speakers so far I want to throw either some Infinity or polk audio in the rear. I guess my question is what are better (or how are they different) Kappa or Reference style speakers?? Also I may scrap the whole Infinity/Polk idea and just go with some 6' Alpine type R's, but I've heard they have issues with the tweeters can anyone confirm? Anyway thanks for your time and be patient with my beginner lever questions, thanks.
