Question about Kole audio KMX-15 Car Subwoofer

1 Answer

Trying to put ported reccomended subs in sealed box.

Hello, I was thinking about trying a pair of the Kole Audio KMX-15 subs. Only problem is that I have made a custom box that is only 1.6 cubic ft. per side and sealed. These subs only reccomend a 3 ft. ported enclosure. Can I even put these in a sealed box? Or what will happen? Also I have some 4 inch ports ithat I could put one in each , not sure what freq. it would be or if it would sound good. I am running a MA Audio HK4000D amp off 3 batts. will be running 3600W RMS X1 at 2 ohm which is what impedance I am going for. Please let me know if these will work, or if I should just get he Lanzar OPTI1532D subs like planned. Thanks alot!

Well, 1.6 cubic foot for a 15 is not nearly enough. A ported box for 1 15 should be in atleast 3 cubes by itself. I suggest building a new box yourself or getting someone else to do it for you. If factory specs on those subs is no larger than 3 cubes per sub then I'd get the box built to 3 cubes per sub after all displacement and tune it in the upper 30's range. Putting big subs like that in a small sealed enclosure can and will damage a sub. and if you try to port an enclosure that is too small to begin with that will also hurt the woofer. Do it right or learn the hard way.

Yes im trying to figure out what the airspace for a rockford fosgate p1 12 in sub. i want to build a ported box for it to put in a entertainment room


Hello... I can help you with this. The correct airspace for a p1 Fosgate 12 is 1.79 cubic ft. I don't think the performanace of a car audio sub will be the best choice for a home audio application, though I hear of it being done on many occasions. Just that the design of the sub is different for different applications, car, home, p.a., etc. Hope this helped! Good luck with your venture!

I got to 12 they are about 400 watts each what would be a good amp to put on it to lift the subs


Hello jeremymikjha,

Basically you want to match the subs in impedance and power.

With 4 ohm subs wired in parallel, the final load will be 2 ohms. Depending on how hard you want them to hit, a pair of 400 watt RMS subs will need an amp that delivers 600-1,000 watts into a 2 ohm load.

The enclosure you use will also make a big difference. A sealed enclosure will need more power. A ported enclosure will be louder with less power.

The Hifonics shown here would be a good choice for a sealed enclosure. It's rated for 1,100 watts RMS into a 2 ohm load.

http://www.sonicelectronix.com/item_17598_Hifonics+BXi+1610D.html

The Eclipse XA1200 outputs 600 watts RMS into a 2 ohm load. It would power the subs very well in a ported box.

http://www.sonicelectronix.com/item_17598_Hifonics+BXi+1610D.html

Somewhat less expensive but good quality would be one of the Alpine MRP series. The MRP-M500 is only $179.99 at SonicElectronix. It delivers 500 watts. It's big brother is the MRP-M1000 with twice the power. Be sure your subs are securely mounted or this amp will literally "lift the subs".

Hope this helps.

Have kenwood mono amp 4,2,1 ohm capabilitie. What is the best sub to run. The amp is 1600 watts, howmany ohms and 1 or 2 voice coils.


Hello pelikant75,

The best answer depends on your budget for the sub(s) and exactly what kind of sound you are looking to get. Your amps RMS output at 4 ohms is 200 watts and at 2 ohms, it's 400 watts. I could not find that it was 1 ohm stable.

If you are looking for the absolute best bang for your buck, I would highly recommend a pair of entry level MTX 10" subs, model 4501-04, currently priced by Crutchfield at $49.99. And if you buy a pair, they throw in a free Bass Slammer BS210S sealed enclosure. The MTX's power range is 112.5 to 225 watts each, right in there with your amps output. 2 of them in parallel give you a 2 ohm load, just right for your amps best power. And they sound great. You simply can't find a better deal for $100 bucks!

If you want a little better SQ, a pair of Rockford-Fosgate P1S410's should be considered. Again, going to Crutchfield, they currently have this one "BOGO" (buy one get one) for $99.99. You will have to provide your own box, though, no free one with these.

Finally, if you want the best SQ, and your budget allows, consider a set of Alpine SWR-1022D's for $179.99 each. These have dual 2 ohm voice coils, allowing you to series the coils and parallel the subs, resulting in a 2 ohm load to you amp just like the MTX's and RF's recommended above. You will probably want a somewhat larger enclosure for the Alpines as well as a fatter wallet. Your amp is right at the lower end for powering them, so they probably will not be as loud. But they will sound good.

One thing we haven't discussed is the box. The enclosure is just as important, perhaps even more important than the sub(s). More accurate bass is generally produced from a sealed enclosure. A ported enclosure will be louder, but at the expense of sound quality. And whether it's sealed or ported, the enclosure needs to have enough internal volume for the particular sub you are planning to use. A sealed box in the range of .75 to 1 cu/ft will be OK for any of the recommended subs. Add about 15-20% more volume for a ported box and keep in mind that the port needs to be specifically sized for the frequency for which it is tuned.

Hope this helps.

Kole amp in protect mode?


Are you setting the bridge switch for both left and right or are you trying to run both subs off of one set of terminals? If you running the subs off one set of terminals you are effectively running the amp below 2ohms and thus the amp is not 2ohm stable and you will destroy it.

Some amps actually all ready run a bridged output for left/right operation, this could also be the reason why the protection circuit is kicking on.

Either way it's a component mismatch and you either need a stronger amp or different subwoofer setup.

Box dimensions for 15 in cerwin vega


do you want the box ported or unported (holes or no holes) if you don't got a lot of room than you dont want a ported box. keep in mind the box has to have the correct amount of cubic air space or you could seize your sub... if you're building it make sure you use OSB board (oriented strand board) or MDF board(medium density fiber) your sub needs .7cubic feet of air space in an unported box

Finding a good box for the sub


< I design sub enclosures for a living so you are in luck. > The one thing to remember is that generic sub boxes are just that - generic. Even if they have a fancy brand name, unless they are built for the sub you are using you will be making a guess as to how well it works. Don't get me wrong though it may work well in that band pass box, but just imagine how much better it could sound in a custom enclosure. Having said that you have the right idea, and bandpass enclosures can be power-full. If you send me (dynami28@charter.net)
the specs that came with the sub I can give you an idea of what kind of box you should get or, if you want to build your own, I can do the specs on that too. Personally I stay away from bandpass enclosures for one reason. When the subs distorts or gets pushed too hard you can't hear it happening. Since the sub is completely enclosed it's somewhat muffled or insulated so that distortion is hard to hear, which can blow up subs. A good ported enclosure would do well and basic plans should be on Lanzar's website, or available from myself. I do not recommend a sealed enclosure unless these subs will see light duty and you don't expect ground shaking bass. They can sound okay in a sealed box but most car audio enthusiasts like the ported boxes for their increased output and lower tones. Email me if you can't find the specs on those subs I might still have them on file. (Also the enclosure should be at least 3/4" thick MDF with bracing throughout.)
