Hds3 15" to hdc 15"

[Stevenajpvv]

I have 2 Hds3 15" subs and I was wondering if I would need to bore out my cutouts on my enclosure to fit either hdc 3 or hdc 4 15's in them and also would the screw holes match up? The reason I am asking is because I want to upgrade but I do not want to start completely from scratch because my box is perfect for the hdc's 9cubes net after displacement at 30hz

haha I just re read what I wrote and I meant to include the question how do I make them bigger because I don't have the tool to make the hole in the first place, would sanding take too long or is there a better way?

rounded file will work, will just take some effort. Otherwise dremel or die grinder with a sanding roll.

Or just get the HDC4's and more power....I run a few of the HDC4's, nice subs and they get loud....

but even with the hdc 4's, wouldnt I still need to change the cutouts? and yeah my buddy have 2 hdc 18's, donno if they 4 or 3's but they get loud and low.. and each would be seeing around 2500-2700 rms..is that being fair to the subs or will they be asking for more

power?

just relooked at the specs of the hdc 4's, would only have to bore out like 8th inch or so..that is looking like the better choice to me now + They're monsters
