Default Need help setting the gain

Well I had two audiobahn ALUM10N...drivers blew because the gain was set to high I guess. So I contacted VMInnovations and amazingly enough my warranty was still active... So They're sending me 2 brand new ones and My Amp is a Hifonics HFI 2000D . AMP Specs

RMS Power at 4 ohms: 650 watts x 1 chan.
RMS Power at 2 ohms: 1300 watts x 1 chan.
RMS Power at 1 ohms: 2000 watts x 1 chan.
Maximum Power Output: 2000 watts

The specs for the subs are Sensitivity: 95.6 dB 1600 watt peak 800 Watt RMS Frequency response: 20 Hz - 500 Hz Impedance: 6 ohms Dual Voice Coil

The subs are ran at 1.5 Ohms but I'm thinking of wiring them 3ohms so I don't blow the drivers again this time. (Meaning I'd have to wire them separately...but if that means saving my subs for an extra few months til I get my sundown, I'm good for it.) or I can wire them both at 6 ohms

My audiobahns are leaving my sealed box and into a ported box..for I've blown so many subs in a sealed box...plus the sound in my cab isn't all that great.

Hi,

Anyone who thinks a 10" sub is 95.6dB senstivity is utterly deluded.
Or that it can take 800watts RMS, yeah right, do the real maths.

rgds, sreten.

I was gunna say the exact same thing. First I was gunna say dont trust audiobahn's specs, then I was gunna say that sensitivity figure is deff wrong! (well maybe it's correct with cabin gain factored in, or if xmax was very low) And I am not personally a fan of audiobahn's but hey if you're getting new ones for free give Em a shot!!

And with the hifonics amp I'd trust the more conservative 4 ohm rating for low (er) frequencies. Just keep the gain way down on the amp, to avoid clipping / DC voltage from being applied to your subs.

I suppose you could get more speakers, say twice a many. Or turn it down.

well I believe I blew the drivers by having them at 1v gain and I have 8 gauge power wire on it. SO It was receiving the max voltage from the amp.

Sounds like that amp can cook just about any speaker, especally on the bass. The modern switching amps can put out a god awful amount of currnet/power. There are two choices, either install speakers that will take it, or turn it down. Those are the choices.
