i dont even think these subs are comparable.

3in coil vs 4 in coil

The Hdc4 is a 4in coil

My 2 cents is the same as others have already said, The SQ Hdc4 is much better at burbs and can handle a great deal of power doing it imo,

I have a sp4 now I used to run AQ Hdc3 18s and they are great for the price. I love the Sp4 I have and its on 2 IA40.1s right now handles it just fine and can play a long time with no stinky sub smell lol

Wait...I was asking this vs that but I don't see how it's a vs thread!

Tell me...does this smell like chloroform to you?

What a coincidence, I have been searching high and low for a awesome 18" woofer. I've cut it down to two choices and the FI SP4 happens to be one of them. I love to hit the low notes! Looks like most people here prefer the SP4 too.

Sp4 will give you more of the lowend output youre looking for and will take the 3500 just fine with a good box and signal.

Ami said that hdc4 could take 5-7k and I trust his judgement, also hdc4s area more spl oriented sub so it will want to be tuned high with lots of port area (straight from ami)

While sp4 is a much more groundpounding sub with a low fs and i most builds that ive seen them in have 3.5k on each and they seem to really like it but obviously could take more, but that said they can work great with that power if taken into consideration while planning the box

exactly what i was looking for, thanks man i appreciate it very much. you said info on both subs, an u were not saying one is better then the other. thanks!

an for the last time to the other ones saying this is a vs thread its not! read what i was asking about the subs an you will see that
