JL Audio Amps

I'm wondering if the JL E2150 can push 2- 12w3v2 D2's ?

Or would I need to find something higher on the food chain to push those?

With the 10W3v2D2s, you'll need an amplifier that is 1 ohm stereo/2 ohms mono stable or 0.5 ohms mono stable. The E2150 neither provides adequate power nor is it stable into any of these loads. In short, look at another amplifier ... Perhaps a pair of D4s and a Soundstream Rubicon500-1 ?

^x2^

The E2150 would be good for front and rear speakers, but not really suited for sub use.

SHUCKS.

Anymore recommendations?

I'd check out Avionixx...their website can be found on this site

Just click on amplifiers.

JL under rates their subs and they say the 12W3v2 will run 300W RMS...so you have a lot of options. There's a lot of good amps around that power range that won't break the bank.

Heres a newbie question, but I should ask it before I buy something I don't want.

What effect does the variance of ohms have on the subwoofers?

 

[street_accord 10+ year member]

The ohm variance isn't really a subwoofer problem...it's more a problem for your amp. The subs present a particular ohm load to the amplifier depending on how they are wired to it. In return with amplifiers, most will produce more power with lower ohm loads present. However, you must be sure that the amp can handle the load you wish to run it at, if you're looking to go low(ie: 1 ohm or .5 ohm).
