18 BLT or Solo X 18?

[Ryan P]

Going to build the box first for the blow through, and can't decide which sub and amp. It would Be either the solox and 1 or 2 zx2500s or the BLT18 and Hifonics cyclops.


Max box size i can fit is 62 wide x 18 high x 21 long at 11.26 Cubic Feet just the empty box.I listen to only rap, and want it to shake the truck. Any help on designing the box and port would be greatly appreciated

[Heathd]

I would do the 18 inch Fi sub, but I am a little biased I suppose.

[AuburnTruck93]

Hifonics all the way. Never touched a box that big so i wouldnt be able to give u experienced advice.

If your really hungry go for the 18" BLT but if your looking for a subwoofer i guess the solo x? Depends if you want a big sandwich or a big subwoofer...

x 2

[95_Sierra]

Joking aside, what kind of amp do you have? Also, is price a concern to you? The BTL will probably be cheaper IIRC... Both companies are said to have great customer service and im sure they would be extra good to someone who buys their top of the line subwoofer....

[Supergumby5000]

the solo X is going to be strictly SPL. They sound like ass, but get loud.

a BTL wont get quite as loud as a solo X without a darn nice enclosure, but sounds worlds better

[Nickleahy23]

BTL all the way..Mine with just a Kicker KX2500.1 and dual optimas is badass...I havent gotten it metered yet but im going to..Here is a vid of it. Box is around 7 cubes and its ported 31 hz.It sounds great and gets real loud..The video it isnt near full power..I need a 300 amp alt first..

What kind of truck are you doing this blow through in? I am planning to do one in mine, but i cant figure out how to do it since i cant mount the sub vertical because its so big..Would have to have some funky angles in the box to make it work..

why not? Do a double baffle and some through-bolts

[Ryan P]

No amp yet. Was going to get it after i pick a sub. Its a 95 standard cab short bed c1500. Was just going to angle the top of the sub back some so it fits, and have the ports behind the seats.

[TurboJugend]

imo your better off getting an amp first, then getting a sub to properly suit it.

ya that is what i was thinking too...Let me know once you get it all figured out..how hardcore are you wanting to go here? My Kicker kx2500.1 puts out 2703 watts RMS at 2 ohms...Its a Dual 1 ohm sub so it works great for the sub..I could run 2 of these amps on the sub if i really wanted to push it, but for daily it is more then enough unless you want to go deaf IMO..Just lots of 0 gauge, Big 3 upgrade and dual batteries and I dont get a ton of voltage drop..a 300 amp alt will cure any that i may have.

[Ryan P]

I want to make it worth cutting a hole in the truck. Want something for semi daily, but want it to be able to get painfully loud also. I ordered the start of the Second Skin Last night, and hopefully will have the box design figured out by this weekend. Going out now to do some figuring on how to position the sub.

[Nickleahy23]

sounds like what im goin for too..I just know that my ears havent hurt from a sub until this one..i used to have 2 15: L7's and i thought that was loud but then i got this and its insane..I also wanted a solo X but after reading about them I went with the BTL..just a better sub for daily

[swacky'sswamper]

How much does one of thosebtl 18's run?I was thnking before od getting a solo 18 from a audio shop arond here for $700.00 new because the guy bought and didn't want it.Do you think that's a good deal?

[Ryan P]

Base BTL is 409 and fully loaded is 499.

[Nickleahy23]

ya thats straight from their website..Solo x's are so power hungry..Sure they get insanely loud, but the box needed for them and the amount of power you will have to run is crazy..They dont sound near as good as the BTL's either..Maybe im just biased but I was dead set on a Solo X until i did some research..

[thekl0wn]

why not? Do a double baffle and some through-bolts

Think about it... If he's wanting a blow through, and there's less than 18" from the bed floor to the bed caps, and he has an 18" sub, he's gonna have some funky angles. :twak:

I know what you were thinking though... Not enough baffle strength to support the magnet hanging off the back, but it's a height issue. :aniteef:

[Ryan P]

See how this setup looks

Hu http://www.pioneerelectronics.com/PUSA/Products/CarAudioVideo/Source/CD-Players/DEH-P980BT

Components http://www.pioneerelectronics.com/PUSA/Products/CarAudioVideo/Speakers/PRS-Series/TS-C720PRS?tab=B

Component amp 2-Channel XXV Juno Amplifier http://www.maxxsonics.com/hifonics/amps_XXV.html

Sub amp 2-Channel XXV Colossus http://www.maxxsonics.com/hifonics/amps_XXV.html

And the fully loaded BTL 18 1 ohm.

I may have figured out a really slick way to build a box to hold the sub. Going to draw it up and build a smaller one out of cardboard and see how it works out.

[thekl0wn]

So what's your sub/amp budget?

For running this large of a setup, I would stay away from a 2-channel amp on your sub(s). Get into a class-D that will give you more efficiency.

I'm anxious to see you box plans as well... Listen to rap, so I'm assuming you're going ported tuned to mid-30's?

[Nickleahy23]

so for taht amp it would be running..

1 x 3200-Watts....Bridged Mono @ 2-Ohms

Thats bridged though...Im not sure if that would be the best for your set up either

[Ryan P]

Say 750 for an amp and the sub is 499. Maybe the XXV Thor?

1-Channel XXV Thor 1 x 1200-Watts....RMS @ 4-Ohms
1 x 2300-Watts....RMS @ 2-Ohms
1 x 3000-Watts....RMS @ 1-Ohm


Not really sure on porting know low sounds better but want it to get loud. What would be a good number in the middle of both?

[Nickleahy23]

for 2300 watts at 2 ohms why noy spend 500 on an amp and get the kicker kx2500.1? Mine came with the birth sheet and put out 2703 watts rms at 2 ohms..Bought mine for around 500

That 18 is going to want to be ported low..What do you consider loud? Something that shakes your chest and moves a ton or air with the lows? Or something that is going to be SPL type and hit the loud notes in the high 40's? Mines ported at 31 hz and it moves some serious air and shakes everything and flexes like crazy

[Ryan P]

Was planning on running it at 1 ohm and yeah i want it to shake everything. Have to find somebody with a Gaylord quick mount bed cover before i can figure out the rest of the box.

[Nickleahy23]

ahh alright..Well you wont want a dual 1 ohm sub then i dont beleive..That will either be set up at 2 ohms of .5 ohms...so you will want an amp that puts out the power at 2 ohms or one that can be .5 ohms stable, which not many can...

[Ryan P]

Ok maybe back to the cyclops? Its $999 tho. Which sub to run it at one ohm?

1-Channel XXV Cyclops 1 x 1500-Watts....RMS @ 4-Ohms
1 x 2900-Watts....RMS @ 2-Ohms
1 x 4000-Watts....RMS @ 1-Ohm

[Nickleahy23]

you would need a dual 2 ohm...but chit man if you were wanting to do that, you could get 2 kicker amps for that price and run them on that sub and be pushing 6000 watts to it...I dont know if you are stuck on Hifonics or what..I was actually the same way as you because that is all i had before..but there are better options out there then the Hifoncs.nno sense in spending 1000 on an amp when you dont need to..

[thekl0wn]

If you're looking at the $1K mark for an amp, I would go with something like this: http://www.soundsolutionsaudio.com/shop/index.php?act=viewProd&productId=152 over a HiFoniks product any day.

Or...
http://www.soundsolutionsaudio.com/shop/index.php?act=viewProd&productId=28 granted it's a bit overrated on the power, but I'd guess less overrated than the HF.

And better...
http://www.soundsolutionsaudio.com/shop/index.php?act=viewProd&productId=191

Kicker gear is pretty solid...
http://www.soundsolutionsaudio.com/shop/index.php?act=viewProd&productId=96
http://www.soundsolutionsaudio.com/shop/index.php?act=viewProd&productId=292

Another good option if you can get up into a 2ohm load...
http://www.soundsolutionsaudio.com/shop/index.php?act=viewProd&productId=288

All-in-all, I would go with any of the above amps over a HiFonics any day of the week, even though the more expensive HF stuff is supposed to be better... I still don't trust them, whereas any of the others I've listed wouldn't scare me to push the power any day...

[Ryan P]

Ok I'll go with 2 zx2500's and use the Kicker ss6.5 components. Would a low tuned box sound ok with rap?

[thekl0wn]

If you're wanting loud, (bass-head), go tuned between 30-36.

[Nickleahy23]

all i listen to is rap and 31 hz is awesome...anywhere from 30-36 would be good...

^^^ beat me to it Klown

[Ryan P]

Ok guess tune at 34. Anyone know the cut lines for the blow through hole? Its not going to be easy to get the amps to look good and not be in the way. Any ideas?

[95_Sierra]

Ive heard its not good to have 2 amps running to one sub.... Or at least harder on it than the same power from one amp... And why do you need 2 2500.1 amps? Im sure one would be enough at 2500 rms... Do you really need 5000rms on the sub? And if you don't have the sub and need it to be a 1 ohm load, just get the dual 2 ohm...

ya i agree...In all honesty i dont want mine any louder for daily...I dont even turn it up all the way when im drivin around because I really value some of my hearing..running 2 would make it insane but I really dont think you need it..If you wanna do that run 2 BTL's and then get some serious bass

[thekl0wn]

If you're going to run 2 amps on one sub, they have to be strappable.

Since you want loud, I'd tune higher...

The Sundown is way more of an amp than the others you are looking at. Grab the 3000d and enjoy!

[mab69us]

9500

[95_Sierra]

What? If you are refering to the mtx 9500, im pretty sure both of these are more of a sub than that... I might be wrong though, just never really heard anyone say mtx is that great...

[Polecat]

unless you do one per coil...we do many installs, two 2500's on one X18.

[Polecat]

not true.

[///M5]

/\ harder to setup as it takes a bit more intelligence in the gain setting, but not harder on the amplifier

[95_Sierra]

I meant harder on the sub but i guess that is wrong... Semms to me like it would be bad to have is cause they don't both put out the exact same power so one would be having to do more work, but i guess thats not the case...

Actually it usually is, but only due to operator error in the setup portion.

no offense, but that wasn't very impressive. the only reason the roof was vibrating like that is because it's very thin sheetmetal, and the sub was upfiring. I didn't see anything on the inside even moving.

[Nickleahy23]

any update on the blowthrough?

[killa66cam]

He prolly never bought the sub or amp/s. I would definately go with the BTL's of the two. Do something that gets the same results for less money. And the BTL's will handle 4000wrms daily...that's a plenty for any daily driver.
