IMO in Ford Cars (Fiesta & Fusion), one should stick to stock sizes only. There are lot of good quality 5X7" options both in components & coaxials.

With this one can avoid cutting and modding the doors. Keep the car in original condition as much as possible.

Round speakers (5.25" or 6.5") can be installed in Ford Fiesta, Mondeo etc without any cutting or modification to door panel or the mounting surface.

hydra
can you tell me why you suggest that i wire at 4 ohms instead of 2 ( and use the mono to its max?)
is it because the ID is rated below 700 anyway and so i dont need to stress my mono unnecesarily?

also the CDT's are out
they are giving me the entry level ones for 24k- im not gonna be interested in that

Also can anyone help me out with the prices and opinions of
Focal polyglass 165V1
and Focal Acces A1 compos

Ajay - what yaar i know the fiesta takes 6.5 i was more interested in your advice on the components and sub choices!

While gurus are here to give you more appropriate explanation, a bit of "theory" I know of is that damping factor will be more in case of 4-ohm, which means more control over the speaker from any given amp. Also, any amp will distort relatively more if feeding 2-ohm. So, 4-ohm should be preferable for SQ while 2-ohm is preferable if want to extract max power from the amp.

Exactly! In addition, there is lesser load on the car at 4 ohm, and you need to use just 4AWG power wire.

If you use a single good sub, you will be feeding the sub well, and still have loads of headroom, even if you wire at 4 ohms. If you go for an IDQv2, you will be overpowering the sub a bit, but with the sub in a sealed box you will get very good results and unless you go really ballistic with the volume knob, the sub will be quite safe.

Why are you keen on two subs?

For a good mono, the amp would mostly be designed to have an acceptable damping factor at rated load.

Distortion would as a matter of fact increase when the amp reaches maximum output, which will happen sooner in the case of higher load impedance.

By running it at lowest rated load, a Class D amp will run with lower distortion at normally used power and the additional power will serve well as headroom.

OH ajayjiii
hmm

i thought of 2 subs
though i SQ is preffered here the chance to show off some SPL too! would be great
Also because is possible here -hehe ( amp is a big one!)
also a sedan allows the liberty to
ive heard a sub in a sealed box in a sedan (yes it was an entry level sub driven with only 300W) but felt 2 would be fun

i know i may be wrong (well LBM's monster proves that!) but i thought i could get the bass louder with 2 subs
if you can suggest a single sub that will give me the same output(loudness and SQ wise too) as two ID V2 (not theoretically but actual experience) i will gladly go for one
but ofcourse that 1 sub should be under 25k

So, it is mainly a trade-off between two factors, THD versus damping factor. You meant to say that at normal power (which I assume would be below 4-ohm rated power), using 2-ohm is an overall better trade-off? Does that change if it is a class A/B amp instead of class-D?

I would certainly think so. This is mostly in the case of Class D only. Few Class AB are 2 ohm stable in bridged mode (which is preferred mode for driving subs). And I would consider it foolish to apply the same logic to a Class AB amplifier and run a 8 ohm load on it , which btw will also exhibit similar charachteristics.

In this case it will reach it's max power limit too soon, right?

Way too soon, because the max power will be very limited.

My monster or my sub ???

And yes there are many 12 inch subs which can come closes to two ID V2

I think he ment was the other way round.You had CLAIMED higher SPL fiqures while using one sub and got Lesser SPL fiqures while using Two subs.
