amp//box//ohm information for 15in. BTL

[00tl 0]

Hey everyone,

So i recently sold my 2 audiobahn 12'' sub woofers, and my amplifier. I have the money now to buy my 15''BTL fully loaded. I had a few questions that i am still not sure about.

1.What should my "ohms" be if im using a mono amplifier.

2.If my box is tuned to 3.25feet at 30HZ is that too little feet, and too low HZ?

3. Does anyone know a good mono amp to go with 1 fi BTL 15inch

4. Also is a BTL legit 2000RMS?

i really aprciate all help, thanks everyone.

1.What should my "ohms" be if im using a mono amplifier.

Depends on what amp you have, although to get the kind of power you'll need for the BTL you'll probably end up with an impedance between a half and 2 ohms...

2.If my box is tuned to 3.25feet at 30HZ is that too little feet, and too low HZ?

On the low end of the recommendations, but they do recommend 3-5cF...

3. Does anyone know a good mono amp to go with 1 fi BTL 15inch

Depends on your budget...

4. Also is a BTL legit 2000RMS?

It'll take that power, yes.

Depends onthe amp. More than likely a dual 2 ohm sub for a 1 ohm load.

2.If my box is tuned to 3.25feet at 30HZ is that too little feet, and too low HZ?

That size/tuning will work great. I personally would tune it at 32-35 Hz for a little extra output. It will still have plenty of low end.

3. Does anyone know a good mono amp to go with 1 fi BTL 15inch

There are too many to list. What is your budget?

4. Also is a BTL legit 2000RMS?

Yes it is.

haha thanks guys,

im looking to spend honestly no more then $300. you guys answered all my questions great except i still dont think i know what these "ohms" are. can anyone explain

Thanks alot

why a btl???

[johnecon2001 82]

An ohm is a measurement of resistance.

Each coil on the BTL is a 2 ohm coil (what you should get). An amplifier will put out varying degrees of power depending on how much resistance is on it. So if you have a sub that can be wired to 1 ohm (DVC2 coils) your amp may put out more power than say at 2 ohms.

[jonbearsmt 919]

are the ohm fi's 2 ohm cause the fi 1 ohms are not 1 ohm.

[JimJ 11]

I have no idea what you said.

[johnecon2001 82]

The BTL's come in DVC1 and DVC2

[jonbearsmt 919]

o chit... what i ment, was... are the dual 2 ohm fis... really 2 ohms a VC...... because the the fi dual 1 ohms,are not 1 ohm each VC.... thay are dual 0.70

[JimJ 11]

1 ohm nominal...impedance changes depending on cone position, so you end up with an "average" of 1 ohm for the entire bandwidth.

Ok so it would be in my best interest to get my 15'' BTL with 2ohms instead of one? should i get it universal or no?

Thanks for all the help everyone i really appreciate it

if you plan on getting another sub later down the line yes.
