Question on FI Q's

[DjiNN 10+ year member]

So i have decided i wanna upgrade from my 10" MTX to 2 FI Q's 10" .... My question is would the FI Q's be good in this box this or should i have someone build me a box? .. second question would be .. What is the BP option? would it be better to get that or leave it? does it help the subwoofer? If i choose both subwoofers at 2ohms what would the load be? 1ohm? what would the load be if it was 1ohms?

yeah you should get your box built by someone

check out the SSA forum on the different options,forgot the link.

depending on your amp,which i think is 1 ohm stable, i would suggest 1 ohm, also load would be 1 ohm.

Definitely get a box made instead of those ported prefabs.

How much power are you going to be giving them? The bp option adds cooling to increase the power handling 200-500 watts (depending on application).

If you got 2 d1 (dual 1) Qs then the final load will be 1 ohm

if you get 2, you have to get dual 4 ohm subs to run at 1 ohm.....

ARSkemp, how you gettin 1 ohm from 2x dual 1 ohm subs

alright .. if i get dual 1ohm would the load be .5ohms? and if its dual 2 the load would be 1ohm? if im not mistaken

I think you would go series on each sub getting 2 ohms per and then into series for 2 ohm.

The Q's only come in D1 or D2 ohm configurations. You will need 2 D1 subwoofers wired in series/parallel for a final impedance of 1 ohm.

Wired like this.

all you need to wire almost any subs in any configuration

yea DHL lost it but claims were filed and refunds were given i think

what would be a decent amp to power these subs .. thinking fo the 2ohm load subs. For the price i think the Hifonics amp is good. Anyone have any opinions?

bump for response on matching amp? 2 Dual 2ohm FI Q's with options.
