Put more money into your front system is also a way to make u feel u get a louder system. A big sub woofer system wont sound that good if u cant get the mid and hi to make upp for it .. Sure u will feel allot off bass and the car will rattle but your still feels like the system does not play as loud as it should. Always got the recommendation to get an amplifier and an decent front system before putting the hole budget on a big expensive sub woofer. A good front system that installed correct can make wounder for your system, even if u get an cheaper woofer to make the budget

Hi! I got 2 older Pioneers TS-W307D2 (800W RMS at 2Ohm). Got it wired down to 2 Ohm and running them on DD DM1000a amp (770W RMS at 2Ohm/ 1000W RMS on 1 Ohm). I like 2Ohm load more because it will draw less current from the batter/alternator, less heat and I also heard quality of sound is better then on 1Ohm. Now maybe I made a mistake with the box or not. I'm trying to save some space in the trunk so I went with sealed box version and sub chambers are not separated. I measured the outside dimension of the box and got 97Liters, lets say from the inside volume is then 87L (I dont know how thick the walls are). What do you think of the box, amp and the subs? I'm thinking in the future I'll change the subs to 2 DD 512d but I'm not sure how much advantage will I have if I buy 2 of them and wire them down to 1 Ohm and have them overpowered by 200W rms or keep the 2 Ohm load and have them underpowed by 30W rms?

You make some good points. My listening has changed, and I like subs that do well in smaller sealed enclosures. I know I lose out on some low end, but It's a good compromise for me. I'd also rather pay a little more and not get rock bottom budget amps. Something like the low end Kicker line is a good compromise for me. Not crazy expensive, but super durable. One thing I'm not sure if you ever mentioned, but ever notice how cabin acoustics make a huge difference. In one car a system sounds great and in another you hardly get any bass.

Question.. I have two d2 crossfire c3 12’s I was originally going to run 3 and wire to 1 ohm to Orion xtr 1500.1 but decided to go with two instead because lack of trunk space. I was considering still running them with the Orion amp at 2 ohms. Big D Wiz said the Orion puts out 1200-1500 watts at two ohms. My subs are 400 rms. After watching this video and seeing you actually get less watts when connected to subs, I’m not sure if I should scrap that plan and just get two d4 subs. I just want the max output I can get from the subs I have, even if I’m running at two ohm and not fully utilizing the amps power. Will I get full potential out of my subs at 2 ohm in your opinion?

One thing that should be added is to make sure your sub and the box are matched fairly well. Spending maybe an hour to familiarize yourself with something like WinISD and your sub"s Thiele / Small parameters will help you match things up much more than just following a generic " 12", 2 cu.ft., tuned to 35 Hz" headline. Checking this out before buying can save you a lot of grief. I know you have tutorials up, and Nick has his tutorials as well. And if anyone has questions, Nick's website forum will be glad to help out.

This is the constant argument I'm having currently with myself. I had that little 500w for 10 days on two subs at 1.5ohm. IT CAUGHT FIRE! Running 4ga power and ground. Gain at 75%. Thinking of getting the JP8 to run just one of the 12s as I bought a new box few weeks ago because the two 12 box was dead. All seams were broken and I didn't really have room for the two 12 box.

Agreed. You can take a cheap driver, and pit it in an excellent built, and properly tuned enclosure, and get killer results. Where as, you can take a high end driver, and put it in an inefficient, poorly designed enclosure, with horrible results. The key, is in the enclosure. For those that do not have table saws, and or experience in enclosure building...get someone to help with a design and a cut sheet. Your local Lowes and Home Depot, will cut your wood at no charge. Then you can glue it and assemble it yourself. Great learning experience all around.

I have (4x) Tannoy SFX 8" active subwoofers for a small listening room. I am looking at replacing their bass drivers with something more efficient and longer cone throw. I can hear 40Hz and below without port chaffing, but the stock bass drivers bottom out max excursions easily and it kinda spoils it. Tannoy had built those subwoofer cabinets excellently as it's a well-known brand in the higher tier of home and professional audio. So from my observations the only thing that limits the subs at the moment is the stock drivers. They're 100 Watt Class AB amplifiers but can easily overpower the drivers. Any suggestions on brands of aftermarket subwoofer drivers?

[@DIYAudioGuy]

If you are looking to drop a driver into the existing enclosure then finding one that fits is job one. I would give these a look: parts-express.sjv.io/a1qmZZ You could make a mounting ring and probably get this one to fit: parts-express.sjv.io/gbjKQB Not sure how those would perform in the existing box, but they are a good place to start.

Id like to know what would be a good tune for 80s 90s country. I made a box a week ago sounded awesome with bass music , put some 80s and country on and it lost about half its bass! I was pissed. Spent all day making it.

[@DIYAudioGuy]

For starters, there's less bass in '80s and '90s country music relative to rap music. No. 808 kick drum, no synthesized bass. The primary fundamental frequency of a kick drum is going to be 60 to 80 HZ. It's going to be about the same for a bass guitar. But don't tune your subwoofer enclosure to that. Most bass guitar cabinets are tuned to around 40 HZ if that gives you any context. The issue is most likely your crossover. Those frequencies are very near the crossover point between your mid-ranges and your subwoofer. Try swapping the polarity on the subwoofer and see if that helps.

I got a used a couple of used Revel subwoofer drivers, they are still working and definitely is a big difference between cheap drivers and high end drivers. I used to think that cheap drivers were similar to expensive drivers like light bulbs, but over the years I can tell that there is a huge difference between cheap and high end drivers. High end subwoofers sound at least 100000 times better than cheap ones, there are tones that a cheap subwoofer will never be able to reproduce, sorry, but search for better quality subwoofers even is they are pre owned.

[@DIYAudioGuy]

There is a big difference between cheap and high end drivers. But, "cheap" is relative and diminishing returns are real. The subwoofer itself is not the weak link in this set up, it is enclosure. That sub sounds great in the right enclosure.

[@ABWSKITCHEN]

@@DIYAudioGuy You need to try any Revel subwoofer, they are a life changer, I owned already over 35 subwoofers in my life, when I tried Revel, they changed my way of thinking about bass.

[@urieldelteco]

Just wish people understood there’s more to an amplifier than the RMS power output. There’s a reason some brands like kicker for fosgate cost more. Factors like efficiency, signal to noise ratio(less important in bass amps), protection circuitry, and reliability are all important factors.

[@DIYAudioGuy]

True

[@damianporter7114]

Could a box too thick effect the performance?

[@DIYAudioGuy]

No. It should sound better if it is thicker.

[@s1wheel4]

I’ve got a quick question here. When you wired the 2 ohm dual coil subwoofer in parallel (on the voice coils) wouldn’t that make a one ohm load to the amp? Now, wouldn’t a mono amplifier split that ohm load in half, so to me, wouldn’t that have made the load on the amp actually 0.5 ohms? Wouldn’t this be somewhat a thermal management and/or a component value failure problem with the amplifier? I might have my math out of wack there. I was just wondering. A cheap amp might not be able to take this for very long IMHO. Thanks!

[@DIYAudioGuy]

Nope, it is still a 1 ohm load. BUT! If you bridged a stereo amp and hooked that to a 1 ohm load it would give you a 0.5 ohm final load.

Before I got a nail gun I used glue and clamps, no screws required.

[@Chuck_Sanders]

Because the glue, when properly applied, is stronger than the wood. The glue will more than hold the panels together. Nails and or screws...are just basically the "clamps". Brad nailing, just holds the panels together, while the glue cures.

[@dannypalmer7701]

Always look for the lowest Hz

[@LstrO42]

Pretty inarguable unless you're talking about sound reinforcement and instrument amplification. Try putting a HP filter at about 38hz on it, and it will play louder than anything you have. The main issue is the box compliance and the mechanical suspension cannot control the cone movement and it becomes erratically unstable, robbing any other potential sound. The big payback for all this processing is the available box gain increases tremendously (3-6 dB), and in the frequencies you have adjusted your box tuning to. The big down side is if the processing fails, everything else probably will too. Try it once, you might be impressed.

[@DIYAudioGuy]

Sound reinforcement is a different game, there is some overlap but definitely outside of my area of expertise.

[@LstrO42]

@@DIYAudioGuy imagine my pain as I constantly hear about low frequency extension that arguably isn't necessary and mdf enclosures that would collapse after a hard week with me, but making a connection nevertheless because what consumers want to hear is invariably linked to my success as a live sound engineer!! My subs fB is 45hz, I can shake your pants at 30' in a 400 cap venue, and I've been using them for every genre imaginable for 10 years. I highly suggest trying the variable HP filter just for kicks. It might make you question the need for the low z's.

[@mizmera]

I have learned 2 things. 1. Buy rms rating. Not pmpo. 2. Anything that just shows 8000w (pmpo) and does not give rms rating is a waste of your money. Bought subs just according to rms and hooked amp on them with same rns rating. Was amazed. For instance. Targa 5500w subwoofer... 600w rms. Pioneer 2000w subwoofer 600w rms.

[@DIYAudioGuy]

Yep max power is meaningless

[@mizmera]

@@DIYAudioGuy i do have a question for you if you dont mind, although I see you are into subs a lot. This is about 6x9s. Remember they always come in pairs. So the rms rating they give, is it for both together or for a single one? For instance on the box it says 60w rms. Does this mean that each speaker can handle 60w by itself, or that each can handle 30w, but together it is 60w? I know it is a silly question, but I ran Kenwood KFCPS6986 (140 watt rms) on my amp which can only do 125w rms per channel. Sounded loud and brilliant. 1 month later both had problems with their tweeters :(. Distortion.

[@DIYAudioGuy]

@@mizmera it depends. Power ratings are often marketing terms as opposed to technical specifications. Sometimes the power rating on the outside of the box is total power for both, sometimes it is per speaker. The only way to know is to dig through the owner's manual.

[@Saltydog547]

I have a 12" subwoofer rated 600w at 1 ohm or 4 ohm and a mono block amplifier rated at 300w at 4 ohm and 600w at 2ohm. This is clearly a mismatch like what you mentioned in the video. I finally settled for running the pair at 4ohm at 300w which is underpowering the subwoofer. Other than not getting the full bang for the buck, will it be any issue if i just leave it like this? Am i going to lose out any details or control in the bass department?

That is a lot of power.

[@bcfmef]

I agree that tuning @ 40HZ is a tad high, but many manufacturers recommend 39-43HZ for many of their subs. Kicker, Rockford Fosgate , MTX … all have subs that require 40 HZ & above tuning for their recommended ported enclosures. Also I agree 5/8” boards are an absolute minimum for an enclosure, especially for the woofer mounting panel. However if properly braced, 5/8” boards can yield proper results. But I would never use that size for an enclosure taking on say more than 500 watts or with a gigantic 1000 watts rms subwoofer.

[@DIYAudioGuy]

My first DIY audio project was a home theater subwoofer. So I am used to tuning much lower.

A shop near my area was selling box that looked to be meant for a 10 inch but with the cutout meant to fit a 12 inch sub. They let me try it cuz the cutout was sooo close to the side walls it looked like the basket would almost touch the walls when installed. And they were selling it for like $100. I looked up the box online, and it did seem like a box for a 10 inch. Online the sub cutout looked to have 2 inches between it and the sidewalls. That box only had a few cm between them. My first box was a used sealed box that had 1 1/5 inch front baffle i paid $25 for it. Super solid box (still have it running to this day.) the box the shop had was probably the same size, but it was a ported box, so it definitely wasnt an upgrade for me. After that i decided to make my first box for a Rockford punch 3. Then i made one for 2 12 in soundqubed hdc3. That set up was too big for my car trunk, and after i got a crossover suv, i turned one hdc3 into an hdx 15, and made another custom box with a round port. The other sub i sold along with the box i built. I just lost trust in car audio shops after seeing all the bad equipment they sold

Quick and dirty numbers I always look for when buying amps is peak RMS @ 4 ohms. There are cheap amps that make good power at 4 ohms and expensive amps that don’t. That’s the true test of an amps “bang for your Buck”

If its ok , I would like to share a track to all the bassheads omongst you, the track is on youtube, Achiel - Enderman (Rob Mitshi) , Its a mean techno track and if you wanna give your speakers a run for some fast paced kickin, this one should do some damage. I love the channel and build my own enclosures. Running my studio with adam Audio A7x's as top units, a 10 inch sub (tremblor 10), and a 12 inch sub ( good old MAGNAT BULLDOG 3000 in a homemade case to add some warmth :). Currently Building a set of 15 inchers to close the deal :). I hope you check me out, if you google me your destined to find some good bass. feel free to put in the comments how U experienced the sound, and what system you used to listen. Thanks for the cool info Audio Guy, you helped me out a lot !!

As far as amps go My only rule = BUILD THE AMPLIFIER (not necessarily the circuit) MYSELF

[@james10739]

I would have thought 40hz was on the low side but ok

[@DIYAudioGuy]

I guess that depends on how you define low.

[@dannypalmer7701]

Bass air must have space to make Bass!a small box cannot multiply sound waves!

[@dannypalmer7701]

You want 20 H-z

[@jumpsuite]

Just because you go down from 2ohms to 1 ohms dose not give more spl or is any better.if a amp can't deliver at 2ohms but delivers at 1 ohm it's not better its not rated correctly. Point is buy a good name brand like alpine Rockford foshgate ect.i know many guys that do this. The thd is my concern.no name amps are never legit high out put ratings are false never true. Just but names you can trust

[@DIYAudioGuy]

You're not wrong. But I don't get too hung up on brand names.

[@cecilhosein4387]

What I realized is imo, older boss amps like the chaos series deliver exactly what they advertise and in some cases even a little bit more

[@blakebrockhaus347]

Yep, there's nothing wrong with something that's good for the money. But you need to spend a certain amount before you actually get something that's worth it

[@DIYAudioGuy]

Right, it is OK to spend more to get more.

[@natskar]

Buy once cry once

[@penttijakonen3817]

Umm, it's never good to get an amplifier that just barely enough powerful and also higher impedance is better for several reasons...

[@DIYAudioGuy]

Right, it is a system and the parts need to match up and pair well together.

[@penttijakonen3817]

@@DIYAudioGuy I just mean that you can't really get a too big amplifier. I rather run too big amplifier at 8 ohms than "right" amplifier in 2 ohms, getting the same power. Not a small budget system for sure though.

[@Thumper68]

Buy a second subwoofer if you already have one and need to wire down.

[@DIYAudioGuy]

Exactly -- got to match those voice coils so that you can get the power out of the amp.

[@Thumper68]

@@DIYAudioGuy yes sir

[@LacerationAudioPinoy]

I dont even know what does a good bass sounds like... My entire system costs about $100 :///

[@LacerationAudioPinoy]

10" subwoofer on an unknown tuned L-ported prefab box

[@DIYAudioGuy]

Budget bass!

[@txkingg]

all this crap is intimidating to new people, that is why the skar packages are great.

[@DIYAudioGuy]

True, one of my goals is to make this accessible to new people.

[@rainbowsnowflake5754]

Having the right box is 75% of the battle to have good sound

[@DIYAudioGuy]

True.

[@kdoeone]

Well if you buy junk you get junk. Buy a great brand like sundown or down for sound. Don't waste your time or money on anything boss or cheaper junk. These amps have always been garbage. 2300 watt amp from jp is under 400 dollars. It's very cheap.

[@DIYAudioGuy]

I agree. Those JP amps are a killer deal. Now that the JP 23 is available in Blue I am going to order one. Also look at NVX amps. bit.ly/3CHGouy

Rule #x: don’t buy an enclose box cause it MUST be calculated according to your driver parameters. Period.
