User questions & answers

Question:	Do these speakers come with grills
Answer:	I have seen Behringer digital amp push them to the max and ,let say, Gemini 4000 watts fails to do anything thing. So it depends which amp you have.
Question:	Anyone put this in the rear deck of a Saab
Answer:	This is a live sound reinforcement driver. The amount of volume in the cab to support it is going to be a significant portion of your trunk. I have two of them in a cab design that is 3.5'x2'x3.5'. My main sub stack is 4 of those cabs, I target each driver at 1500W RMS, however I could easily run it at 3000W no problem but that is going to go past the 2400W program rating which means I have to be careful. It has a 7000W peak but that is the point where you actually damage things. Program ratings are crap. If you want to run the speaker for ever with no damage you need to sit at RMS rating and that is 1200W. If you really want to run a 3000W amp then get two of these and mount them at 90deg angles into an enclosure that has enough volume to support it (like your _entire_ trunk.) Cross mounting them allows them to acoustically couple and you get more output.
Question:	what is the mouting depth
Answer:	Yes you could use that. But this model is known for its power handling. 18lw1400 handle less power and more bass
Question:	Is this and actual Subwoofer
Answer:	The program power of it is 2400 watts.
Question:	whats the lowest amp watts can push this speaker
Answer:	Around 200ish, depending on the flavor. I personally like Quest bars the most, though.
Question:	can i use a rockville amp which a 3000 watts to push this 18 sound speaker
Answer:	Our Chocolate Peanut Butter (P 54472, B 59215) contains highly refined coconut oil. However, the Chewy Chocolate Chip (P 54473, B 59211) and Chocolate Deluxe (P 54474, B 59213) do not contain coconut or coconut oil. Thank you for your interest in Pure Protein!
Question:	Would this be good to use specifically as a subwoofer purely for bass
Answer:	Here's the info on the chocolate one. If I had to summarize, I would say avoid it. Maltitol spikes blood glucose and causes gastric problems, and the carb count is too high. There are many better choices.

Question:	how much watt one of these speaker have
Answer:	Regarding the earlier answer from C.A.: "Also, there is no such thing as "natural" anything (there is no FDA definition for natural), much less "natural flavoring"." You just made that up, lol. The FDA defines natural flavoring in 21 C.F.R. 501 "The term natural flavor or natural flavoring means the essential oil, oleoresin, essence or extractive, protein hydrolysate, distillate, or any product of roasting, heating or enzymolysis, which contains the flavoring constituents derived from a spice, fruit or fruit juice, vegetable or vegetable juice, edible yeast, herb, bark, bud, root, leaf or similar plant material, meat, seafood, poultry, eggs, dairy products, or fermentation products thereof" The flavoring on these bars is really good. You can also CAPS LOCK chemically sounding names all you want to make them appear sinister, but that doesn't make it true. "CALCIUM CARBONATE" - seriously? That's the 20% DV of calcium and is also the active ingredient of Tums.

Answer:	No, these are a factory replacment speaker designed to fit under your cars factory grills.
Question:	can i add it to my logitech z906 without an amp

User questions & answers

Question:	Do you recommend this speaker for a dj system that’s playing rugged bass
Answer:	No problem with AppleJust laura via Bluetooth
Question:	What are the Hz numbers
Answer:	This is just a speaker and requires its own amplifier to power it. That Logitech has power built in to the sub woofer, this does not. So I guess the answer is no. Also the Logitech splits your highs and lows and powers the smaller satellite speakers. This is made to go in a car or truck with a car stereo and it’s own deprecate amplifier.
Question:	Can u put them in your car doors
Answer:	I say yes as long as you have the appropriate equipment. I have this 400 watt amp hooked up to it. It gives me some rich base that can be heard throught the cabin but not outside the car due to tge low wattage.
Question:	Are they easy to blow

User questions & answers

Question:	I have a chevy s10 2000 single cab and I wanted to know if it will fit in the back of my seat. what box should I get to fit my truck
Answer:	I never measured it but the system is designed to maintain nominal load under all conditions. Mine works fine on a whole house system with all outputs wired. Keep the same speakers per load connected, i.e. use only 8 ohms speakers.
Question:	Why are they making a popping rattling noise
Answer:	A "passive' subwoofer (no internal amplifier) is just a speaker with a low pass crossover, which would be fine. If you have a "powered" subwoofer, you would use a line level audio signal from the amplifier line out, not a speaker output [even though that is also possible with some powered subs with input attenuation].
Question:	What is the recommend air space for these
Answer:	I think Mr. P means to ask if it uses autotransformers, which can be used in audio applications to adapt speakers to constant-voltage audio distribution systems, and for impedance matching such as between a low-impedance microphone and a high-impedance amplifier input.
Question:	Does this come with a grill
Answer:	It does not require any power.

Alphasonik Subwoofer Innovation

The Treis Series shallow mount subwoofers are designed to deliver true subwoofer sound in a form that has a mounting depth of 3.54'. Alphasonik engineers recognized that there are scenarios where you just can't fit a full size subwoofer behind the seat in a pickup truck, in convertibles, in the trunk with golf bags, strollers, or whatever other assorted goodies we drive around with. Other shallow mount subwoofers in the market are not able to deliver true subwoofer performance, they are more like mid-bass drivers, unable to play those truly low notes that make owning a subwoofer fun.

Design

The Treis series was designed with a Spun aluminum cone fore accurate and ground breaking bass. Also, Alphasonik engineers added EPDM Surround for Enhanced control at Extreme Temperatures.

User questions & answers

Question:	This sub doesnt have a power cord, so how do you power it up
Answer:	Not sure on the 3rd gen 4Runner, but will not fit as-is in a 1st gen ('84-'89) 4Runner. I had to modify the antenna mount slightly to get it to work:- http://www.4crawler.com/4x4/CheapTricks/AntennaReplacement/6.htmlProblem is there is not enough room behind the hole in the fender to allow the rigid part of the antenna base to insert fully at the angle it needs to be. So my adapter lets it stand straight up and down and then there is plenty of room and it works great.
Question:	What are the actual dimensions of the sub woofer itself
Answer:	depends where antennae is
Question:	Is it dual 4 ohm voice coil or a single 8 ohm
Answer:	If your car has the Motorola antenna then it plugs into that to make it longer, So lets say you have a car where you are installing an aftermarket stereo and your antenna won't reach the antenna hole on the radio you would plug the female side to the factory and the male side in the aftermarket radio.
Question:	dollars and no manual. 4cwires in cable. black, yellow, blue, brown. blue and brown are cut. do i have to break out the volt meter
Answer:	I don't know about a 1999 jeep wrangler, but I do know that it will fit older standard OEM radios, and aftermarket radios. I purchased it for an extension to an aftermarket Pioneer radio for a 1963 Mercury Meteor, but it would also fit the factory installed radio.
