Dilemma... 12" Fi SSD, 800 x 2 or A Mono 1600???(abbreviation help too)

[fritosaregood]

so i should decide on an amp b4 the subs?

you need to match them up, yes.

I would stick with a mono amp. Most are class d amps which are more efficient, cheaper since they dont have the bigger crossovers built in that will be useless when using it for subs, and it will usually have a subsonic filter

I'm Looking into upgrading from 1 12" sub to 2 12" Fi SSD's. I'm still shopping around & looking for suggestions on amp & how I should set it up. I was wondering if I should run 2 - 800 Rms amps, 1 - 800 x 2 channel, or if 1 - 1600 x 1 channel is possible.

I was also wondering if someone could clear up what some of these abbreviations mean.

Fs: 30.1 Hz | 30.1 Hz

Re: 0.7 Ohms/coil | 1.4 Ohms/coil

Qms: 7.65 | 7.65

Qes: .37 | .37

Qts: .36 | .36

Mms: 248g | 248g

Cms: 0.11mm/N | 0.11mm/N

Sd: 480cm^2 | 480cm^2

Vas: 36.5 l | 36.5 l

Spl: 86.1dB 1W/1m | 86.1dB 1W/1m

Bl: 13.1 N/A | 18.7 N/A

Fs = resonant frequency of the speaker

Re = dc resistance of the coil

Qts = the total quality factor of the speaker at Fs

Vas = volume of air that offers the same degree of restoring force on the cone as that of the cone's suspension

Spl = sensitivity of the speaker at 1 watt RMS (different companies measure it at 0.5m) But the standard is 1 meter

Thats all I know
