Looking for SQ: ID or Fi?

[snypaz 10+ year member]

I want a good sq sub and a lot of people recommend the ID IDQ12 or Fi Q12 but if you had a choice which one would you pick? I am open to other sq sub suggestions as well. Thanks!

edit: forgot to add, just a single 12" and probably sealed because I need space

That would depend on the power you want to throw at it. The IDQ handles up to 500 rms with 14 mm of xmax, the Q will be double on everything from power (1000 rms) to x-max (27mm) Both subs sound amazing, but the Q will have more output.

X2. I love the sq that my IDQ has, jus the output isnt the strongest. Id say go with whatever sub that matches best with your amp. Anything over 450-500 watts you can pretty much rule out the IDQ.

Stereo Integrity BM if you can go ported as they are not sealed subs, or SI Mag if you can find one used.

Aren't those SPL subs?

No, more SQ with some get loud capabilities. Mags sound beautiful

IDQ v3 has a little more xmax, 12's aren't available yet.

If you aren't horribly concerned about price you could go with a pair of IDQ's to handle a bigger amp. The IDQ line requires a lot less airspace than typical subs so you can fit 2 of them in roughly the same amount of space that you'd need for 1 of another.

For example, the recommended enclosure size for a sealed FiQ per their website is ".8-1.5 cuft" while a single IDQ.v2 sealed recommends ".55 - 1.00 cu. ft". So if you were going for the smallest size possible you'd have to use a little more space for the IDQ's [.55x2=1.1 for IDQ vs .8 for FiQ], but IMHO it'd be worth it. Granted I have never heard the FiQ myself, but I have never read a comparative review where the FiQ came out on top for SQ, especially when comparing it to the Mag or IDMax/Q. Plus I own a pair of sealed IDQ.v1's and love them so there. =P

Never heard a 12, but had an IDQ10v2 and it was quiet as a wee little church mouse.

if you compare ID to Fi, i would compare IDMAX to FiQ.

Not IDQ12 to FiQ.

out of these two i would get the FiQ

The SI subs? SI does not make anything for pure SPL, They are SQL, they sound amazing but also get pretty **** loud.

My vote is for the Fi Q. As I have 2, and love them.

I am most likely going to go with a Fi Q 12" and a 1000 RMS amp but I have one last question; can my stock electrical handle it? The car is a 2006 BMW 325i (e90) with a 180A stock alternator without the big 3 (maybe 2?). My stock battery is located in the trunk so running a new wire from the alternator to it will be a huge pain in the ass but I can do the other two. The only thing I want to add to my car is an amp and a sub, will it be fine?

sounds like your electrical should be just fine. if your amp really is 180A, and your battery is in the back, you should be set.

If you want a pure sq driver look at the SSA Icon or the Si mag/bm

both are based on sounding good, althogu they may get loud
