ok not the best when comming to amps but heres whut i need to know. I bought 2 12"W0's (JL AUDIO)

specs:

Nominal Diameter: 12 inches (300 mm)

Continuous Power Handling: 125 Watts

Voice Coil: 1.38" diameter, 6-layer, Kapton former

Available Configurations: 4 ohm or 8 ohm (Single Voice Coil)

Xmax (one-way, linear): 0.34" (8.6 mm)

Ported Enclosure Range: 1.75-2.75 cu.ft. (49.5-78.0 liters)

VRC™ Technology: YES

now i was wondering if the 2004 JL AUDIO E1200 MONO SUBWOOFER AMP would power my 2 12s?

Dimensions:

9.8" x 9.25" x 2.36"

Features:

Absolute Symmetry™ Class AB Circuit (U.S. Patent #6,294,959)

Differential, Noise-Cancelling Input Topology:

RCA jack inputs (low-level) and multi-pin jack (high-level)

On-board Crossover:

State-variable, 12dB/octave Butterworth with continuously variable cutoff frequency selection from 50 – 200 Hz. Configurable as Low-Pass or High-Pass

Preamp Output:

Pass-through type.

Speaker output connections:

If you have single 4 ohm subs then it will work fine.

 

[F-Ranger]

but if its 8 ohm then it wont work? it says this on the page i bought it from

"Voice Coil: Single " so is that 4 ohm?

 

[JimJ 5,000+ posts]

Does it say 8 ohms or 4 ohms on the page you bought it from? Or does it say on the sub?

 

[iceteebone 5,000+ posts]

if it is 8 ohm it will still work but you could only wire it down to 4 ohms and only get 120 rms.

havent talked to the guy yet but these are them http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&category=39776&item=5745751988&rd=1#ebayphotohosting

or would the JL AUDIO E2150 2 Channel Amplifier work better?

anyone need to know quick!

Anyone ?!?!?!?!?

The original amp you asked about (the E1200) would work great as long as each sub is 4ohm. If they are both 4ohm, then you could wire them in parallel for a 2ohm load on the amp, which would give you 100w per sub

 

[F-Ranger]

ok whut about the E2150?

 

[squeak9798 5,000+ posts]

ok whut about the E2150?

The other amp would be much better. With the E2150, each sub would only get 45w, as opposed to 100w each with the E1200 (again, assuming each sub is 4ohm)

I would look into this amp especially if you are looking at a 4 ohm final load, if it is a final 2 ohm load watch you gains and you should be fine.

Dude you need to have all the info before you ask a question. What voice coil config. are the subs. Single 2, 4, 8 or dual 2, 4, 8ohms.

 

[F-Ranger]

the subs are 4 ohm.. just found out! so the JL AUDIO E1200 should power it no problem?

well with 2 dual 4 ohm subs you can either run them at 4 or 1 ohm, so the E1200 would not be a good choice considering each sub will only get 60 watts rms.
