Well Im going to be putting Two tens in an altima coupe and they will be powered by a sundown 1500. I was thinking Either 2 fi qs, bls or 2 audioque hdc3s what would you recommend??

hey guys i built a sub box for my friend 3.5 cubes at 40 hz aero ported. we put a alpine type r 15 in it and we blew it in a day i was running 1100 watts rms into it i know its only rated for 750 rms . i was running that 15 in a 34 hz 3.5 cube box with no problem with the same amp. Why is that the cone seperated from the voice coil. is it cause of more air flow it over extended? so which sub should i go with an fi? sound splinter? aa? ssa? and he wants to spend at most 250 for a 15. Oh and by the way i never heard a type r 15 get so loud that box made it rediculous. thanks guys in advance Billy

Im bout to buy 2x 18" RD Audio Alpha V.2 subs from someone on here.... I was wondering if anyone knew the recommended airspace for each sub, and the best tuning frequency for these subs as well.... as of now, I have a box designed for both at 13 ft3 after port displacement and drivers and crap with a port space of 177 square inches and 20" long tuned to 34hz.... so basically im giving each sub around 6.5 ft3 tuned to 34hz ..... to me, this seems good, but I was wondering if anyone on here has played with these subs and if you could give me your opinion on the best box to run these things in? RDAudio.net doesn't have the box recommendations up yet... sooooo help please....…

I currently have a 3cuft3 box tuned at 40hz for my Soundstream SPLX sub @ 1k rms. I found out that the box is way to big for this sub thats why it sounds like the bass is "lagging". I have looked around and found that the Mach5 SPL 12" is the best for price to performance ratio but i have a couple questions that you guys might be able to answer. What size box will i need and whats the best tuning frequency for a loud daily running 2k rms (Unless thats to much) And will i have to order one from the US as i am from Australia but the Aus site only lists the SPL 15" not the 12" and my email hasn't been replied to. Last of all what is the quality like on these for music i no …

I saw this video and though it was insane and wanted to share. Enjoy.

4 LV518s and 1 hifonics amp, did a 159.6, not to bad. the loudest its been befor with just the 1 amp in there with other woofers ive tryed is 158.6 so +1 db =]

OK. Im building a box for my S-10 blazer and i need help with the port. The box is 38" wide 19" high and 14.5" Deep. It hold 4 RE SR 10 D4's. Id like the port to be now wider than 10" no taller than 6". id like it to be alot wider than taller just to kinda "fit" better... Thanks in advance -Mike

Whats the difference between Fo and Fs

So I have a 15" fi Q with a 1500 watt clarion amp in my accord, but im looking to trade in the q for something else. I can not afford a new amp, or any electronics upgrades, so 1500 @ 1 ohm is my max power. Im tired of the q because i have almost no trunk space right now and it makes grocery shopping for 3 or 4 people kind of difficult. Im not sure if it would sound good in a 3^3 ish box but FI says it can be from 2.8-4, but something new is always fun so ill probably switch out. I want to stay as close as possible to as loud as I am now, and want it to sound even from low lows to higher lows...(my 45-60 response is rather weak right now but i think its because its a 4^3 …

whats the difference between the lvl4 coil and a lvl 5 coil on a dc lvl 4 18? im going to be getting 2 lvl 4 18's and a sundown saz 3000d

Looking at treo ssi 12 or ssx 12 are either of these decent subs?

Looking for new setup. From the sounds of it, Fi seems to be the way to go. I have a Chevy Blazer and I like to listen to mainly rap with deep bass sounds. The Fi BL 15" or 18" look like they will do the job. Still undecided on the amp to run this. After looking around, Sundown or RF look like they would be well suited to handle it. Will they're be any other things that I will need if I run this? Advice appreciated.

I have 2 MJM 18s and they are in a 12 cube 32 hz box oriented like this okay im wondering if it will help at all like this I didnt account for the Double baffle and the 3/4 sheet under the box to get it off my wires, and make it easy to move when i need to. its about 3-4" away from the roof, and i swear all the sounds going outta the car LOL, So will that help or hurt me BTW its in this

Has anyone played with these before? How are they and how much power do they really need?

Im goin to be buying some 10s soon and I was wanting to know what the difference in the 10 inch FI Q and the 10 inch ICONs are? Im looking for a sub that will sound clean and drop low while being loud aswell. I was goin for the AQ HDC3 10 subs at first but I am wanting to meet my expectations running only 2200 rms watts. Not to mention also sounding clean. I know the FI Q and the ICONs are known for their good sq but which one will get louder off 1k rms to each sub?

Well i am fixing to give you guys a try out. I will be walling off a 93 Geo Prizm with 2 lvl 5 18's and 2 sundown 3000's. thought id post this here as i will have the car at the builders house maybe next week. Any advice on the LVL 5's. i plan to tune between 32-35hz!

With only 800-900rms total

Right now I am running 2 polk momo 12's single vc, in sealed 1 cube boxes behind my seat. I am thinking of switching to 1 12 in a ported box and adding 2 8's for some more midbass. I dont have the room to port both subs. The sealed box are fine but I listen to a wide range of music, sometimes they dont hit the low low notes as well as I want them. I was just wonder if there was any suggestions about the quality of sound or should I just suck it up. I dont want to cut the back wall or anything, though I am thinking about modding the rear speaker spots on the wall behind the door/ seat for the 8's. I have a good sound for the most part it s just hitting the hard low notes…

does anybody know it? IIRC its 17 1/4, but i dont remember i emailed Mach5, but its sunday and dont know if they will reply... thanks in advance....

So here's the scoop. I have A 2004 Dodge Ram quad cab that i plan on outfitting this spring, and I am very indecisive so I figure I better start planning things out now. I have learned from this forum and my own mistakes to start with the front stage, so that's where I'm at. Right now there are 6x9s in the front and 5.25s in the rear. I am thinking of doing 6.5 componants up front and just leaving the rear alone, unless it is greatly beneficial. I guess my first question is active or passive. I have never run active, but if the sound difference will be noticebale than it's worth it to me. The head unit right now is an alpine 9886, I do not have the imprint option f…

I just built a box for two audiopulse axis's sealed, with one ive used for a while and a brand new one. They are both dual 2 ohm, I got the box all finished and wired all the coils in series for an 8 ohm load for my home amp for testing, and nothin came one. I checked the final resistance of the box and it read invalid. I pulled the new sub out and checked each coil and they showed the right resistance, i pulled my older one out and it showed resistance in one coil but in the other it was invalid. I pulled the older sub out of its old box two days ago and it had a thin layer of saw dust on parts of it, i guess i didnt clean out the box all the way. I used one of the micro…

OK guys here's the question, will it be a big difference on the meter and by ear going from 4x RE SX 12" (powered by 2x USAmps MD-3D in an 7 ft^3 tuned at 34Hz) to 4x RE MT 12" in the same box and tuning but power by (4x MD-3D thus one Amp per MT's) I assume the MT is similar to the BTL's and they recommend 1.75ft^3 per 12" BTL drivers, so it will work ok. Will you notice a Big difference in loudness, and is it worth it the change? and how about to 4x FI BTL 12" in the same box and the 4x MD-3D? Anyways, thanks. Aruman

Do the 3" Legatia mids have grilles available? I need to find something to fill these holes left by the 3.5" DLS Ultimate Iridiums the previous owner had and these seem to be one of the only good fits
