From: Brand new subs nearly no bass?

[brian p 1]

So i recived my Fi BTL n2 12"s which are 2x2 dvc and wired them like this:

Voice coils in series and woofers in parallel should give 2 ohm final load (reads 1.3ohm on DMM). My RF 2500bdcp amp does 3500w at 2 ohms @ 14.4v (not sure if i shall belive the birthsheet)

The woofers are mounted in a temp ported box till next week when i build my enclousure which will be 4.5cu after displacment and tuned at 33hz.

As it is now it dosnt give out much bass at all, don't know if they are out of phase or that they are brand new and stiff as hell or it just might be the box.

My voltage is steady even at full volume before clipping. (14.7v) i've scoped everything to make sure nothing clips.

woofers dosnt get hot they are ice cold , but the heatsink around the RF amp get really hot but on top of the amp its just warm.

My brother got two kicker cvx 12" running at 1800w 1 ohm and they pound. and i did the wiring :S so something must be wrong...

Power and ground is 0ga, speaker wire is nice and thick, XSpower d3400 up front and 270a dc power alt.

Hope someone can find the problem, there must be something wrong :s

check phase
