I've seen a lot of topics about resistance so i decided to make topic about this to clear things up. There are 3 ways how to run your dual coil sub. 1) Series connection: you will wire your sub in series. If you connect in series you add resistance. 1+1=2 ohms 2+2=4 ohms 4+4=8 ohms 2) Parallel connection: Hook up your sub in parallel. Making your resistance lower. 1/1+1/1+1/2 = 0.5 ohms 1/2+1/2+1/1 = 1 ohm 1/4+1/4+1/0.5 = 2 ohms 3) Or you can run dual channel amp, 1 coil to 1 channel. Or run 2 amps one amp to one channel. I actually don't recommend this connection, because coils have to be powered equally, you need to make really accurate settings. Hope that this helps yo…

Hey guys I am looking to get a 15" in the 1500-2000 RMS range, depending on what would work best with my final decision. I listen to mostly Rock, Alternative and Rap/Hip-Hop. I like getting loud more then really caring about quality. So I believe a driver geared more towards SPL might be a good decision?? This set-up will be going in my Extended Cab Ram, so I have quite a bit of room to work with. Sub: Sounds like XCON might not be a bad choice. Even though its more SQ then SPL? Need suggestions. Would like to get Dual 2. Amp: Sundown SAZ- 2000/1500D would be my #1 choice. Depending on driver choice. Looking to run it at 1 ohm. Box: A local shop does good work on boxes s…

I'm posting this thread in the general section so that maybe more people will see it. This is a plea to get people to write product reviews. In my opinion, that is one of the most valuable resources that this forum can have yet it is being severely underutilized. Write a review about all of your equipment, not just subs (as I know that's the most popular). We get many threads each day with people trying to figure out what equipment to buy and we could point them to the review section. But right now there are about four reviews in the last four months in there. However, there is a caveat to my encouragement. Please write a good review. This includes positives and neg…

Hey guys I have a little project I need help with. I recently purchased a new head unit with a monitor, replacing my old Pioneer 4000UB with iPod control. The new unit only has RCA Aux-In and does not offer iPod integration. What I am trying to accomplish is have my iPod play audio output through the sound system (two amps - one for mids/highs and one for subs) independent of the head unit, so I can play videos/movies on the head unit while still having the option to listen to a different track than what's being outputted from the movie... if that makes sense. It would be an easy solution to plug the iPod directly to the Aux-In of the head unit but then the screens would…

Why do you use a 50 or 60 hz test tone to set an amp whether then the lowest frequency the given speaker will be producing?

I posted this over on the Mach 5 Audio section, too. Some short videoes of my 6th order wall in my Jeep. Two Mach 5 SPL 15's and an American Bass XD1800, so not a whole lot of power. My Powerbass XA3000D is in for repair. Still have a lot of tweaking and testing to get this build running full tilt. Thanks for the views!

How much would two Havoc 12s run me? And what would the best amp for my money be if i do end up getting them?

does anyone know what grade home depot or lowes MDF is. ive got a few ganahl lumbers and reel lumber by me and they use grade a. ive used the A before and i liked it better and it seemed to be better quality than HD while still bein only $25 a sheet

Hey everyone, Now I have everything need to get it all installed. I live in Bay City Michigan 48708. Know of anyone who installs in the area?

hey guys i turned on my sub today and got a new weird sound ive never heard before. everything has been fine the last few months, until today. it sounds like a lower pitched rattle of some sort. i listened and it seemed to be coming out of the port. i could smell just a hint of glue, and the cone was warm. anyone got any ideas? if you need any more info just let me know, ill do my best to get it. thanks.

Sorry about this really really , noobish question but i was doing research and couldn't find this answer out myself. Materials : AMP- http://www.shopping.com/xPO-Pyramid-PB448 (worst amp in life, but its all i have laying around , until my other one ships in mail. SUB - Fi SSD 15 DVC 2 ohm. Is it possible to wire up the left REAR channel of the amp to one voice coil and the other voice coil to the right REAR channel of the amp to get the 250rms per channel @ 4 ohm. to equal 500rms. or since the amp is brigdable , wire both voice coils together and bridge them into one channel? (AMP is not 1 ohm stable , so i'd need to wire them for 4 ohm.) Thanks i just wanted to a…

So. i have been wondering, what is better for bass. An '02 lincoln towncar, or the 89 crown vic. both have trunks the size of a small house, and both guzzle gas. But what would be the better choice? For the sake of argument, both are show off cars, music-wise, and for looks, both would sit on 22" blades (or maybe spokes for the Linc). The intention is a low-end beast. crushing lows. For whichever you choose, list the setup you would think is best for the space available. I am considering one or the other as a 2nd, 3rd, or maybe 4th car after I run in the bug. I would like the lincoln, but my concern is that, I lack the experience in cars to treat it the right way, i'm v…

Fi SSD 15 . Copper Coil How much RMS will this take without any chance of blowing. Says 800rms, but how much will it take to really slam, safely, (my box is 3.5 cubic feet. 33hz)

does anybody have experience with the trunk space of a zx3 2002 ford focus? i guess it doesnt have to necessarily be 2002, but at least the same body style. Im recommending the BTL to my friend based on his goals and because im a Fi fan. he wants to be as loud as he can get with one btl, and hes pretty noob so immediately he assumed the 18 would be best for him. so what im asking is does anyone know if a box big enough for an 18 will fit in the focus's trunk? i dont have the dimensions, although i might later on when i talk to him. and it can take up the whole trunk except a lil room for the amp (most likely going to be an audioque 1200d.) hes probably just gonna be…

I have called all the local car audio shops trying to find someone with a TL. I just don't want to spend $650 on a meter, when I could buy another sundown audio 3000D for that. I'm just asking if anyone knows of a place that has a TL anywhere in the montgomery or birmingham alabama area. Thanks. Are there other types of meters that are close to that of the tl, but aren't as expensive?

I just got a Kicker L7 12 2 ohm and I have an alpine m500 amp, i know its underpowered but it seems to be bottoming out or clipping. It just sounds awful. I dont know if i described this very well just ask and ill provide information where needed. Is it just a tuning problem? Also it will just cut off when the volume gets to loud.

What makes your setup hit your chest hard? Is it the RMS amount? Box Tuning? Sub? What would be the best way to get the hard hitting, urghh my chest bass (: I have an Fi SSD 15(copper coil), just built the box , tuned to 33hz, 3.44 cubic ft. Powerd by a hifonics 1206d. Box is built just waiting on the Sub to come in the mail. If this setup isn't going to do it, then thats alright. But what is this build good for?

Hey guys i found this great deal on G31 shipped for 150 each. and i was looking for a review on these batteries? like has anyone had any previews experience with these batteries? also more importantly that price seems really low to me is that the price they go for normally? and one more thing these are BLANK deka g31's. which means they don't have a label on them the seller does say they are 100% deka's though? any thoughts or recommendations? thanks for your time Kenneth

What's the difference between these, what would be the best ?

So Ive been thinking about it and seems like it would be fun. I know nothing about running in comps and would like a little info on how. I know there is a ton of different classes to be in but I dont have a clue about them. Do they go by how much power you run, how many and how big your subs are, or if you have a wall or somethin? I always see these posts about going to shows and you guys make it sound fun. Id appreciate it if I could get a little rundown on what might be best for me with the stuff in my sig. Any info would be awesome. Thanks guys.

I have one question only, dont hate just answer I am deciding between the BL 12 and the Icon 12, I know these subs are made for somewhat different applications but jus bare with me. Both these subs are put in ported boxes made specifically to standars and hooked up to a saz-1000d. Which one is audibly louder?

My first question is what subs can take 4kw+plus rms because i have 4 Rf 4000.1bd amps and was wondering what subs could take that kind of power????

As the topic title says. I need to custom build a set of RCA cables. I currently am running a TON of Y connectors to get the job done so I want to swap and only have to run one cable that has all the ends I need already soldered inplace. it'd be a 1-in 6 (or 8) out cable My current deck only has one preout-mono sub (with one rca only not a pair) I may split it at a line driver then run a 2-8 cable instead of the 1-8. So far I don't have voltage issues but I'm afraid if I keep Y'ing it off the voltage will become very weak at the amps. So if anyone knows af somewhere cheap and decent to get parts let me know.. I need to get these built ASAP... I think my local radiosh…

A buddy of mine is looking to upgrade his audio, and between him and I we are trying to get some ideas about what to buy. He has a new(ish) (2004-2006 probably) cadillac escalade. Not positive of the max dims, but I can get exacts if necessary. I'm just assuming similar to most other large SUV's. He is running his stock head unit but willing to upgrade if necessary, which will most likely happen. He is considering (2) 18's or maybe even (4) 15's or 18's. I am looking for suggestions as to what subs and amps to buy, but even more so to what else is necessary to accomodate such a large amount of RMS. He is running his stock alt. So, besides the Big 3 which I know he wi…
