Whats the best way to cut a 14in diameter hole in plexiglass?

Also, cut a 5in diameter hole in fiberglass?

Thanks.

I'm changing subs cuz I wanna try a single sub setup, I wanna try a 15 as I've never had one to toy with, and cuz I'm bored with it lol. I'm not tryin to improve anything, I'm tryin to make a change, but make the best change of that makes sense.

Also I have room I really don't care about trunk space lol I have 2 sa-12s ported right now.

Considering the fi ssd 15 as of now. Xmax is 20mm I think

I like the ssd, would I be more suited with a 10 or 15? I listen to rap mostly, but other stuff here and there and I want sq mainly.

Whatever need be really. Right now I have a 1200d mono hifonics and bouta get my sundown 1200d mono repaired. But I can always get an amp to match the sub.

What 10" would you recommend for sq in the 200 dollar range?

It'll be a daily setup in my altimas trunk. Goin for sq over spl.

As versatile I mean like pick up those low bass notes and keep up with the higher ones

I think the saying "you get what you pay for" is true. That bein said would it be wiser to get a better quality 10" sub or a lesser quality 15" sub? Or is that just a favor of difference in a punchy 10 or versatile 15?

Is there anything you've ever heard of or done to a box that's uncommon and maybe out of the ordinary that increases sq? I'm aiming for sq I don't care about spl so much lol. Just wantin to try and discover new things pretty much.

Would it be a benefit to help the air flow of the port. Like add angles causing a smoother flow of air from the driver to and throughout the vent?

Building a new box for 1 15". Was gunna make it an abnormal shape as opposed to the everyday cube. I've heard that less parallel sides results in less standing waves, but I don't think it would be too noticeable in car audio. Anyway my point is wanting opinion on the ideal shape of a box. Also plan to port it. Thanks.

You need to give more info about the enclosure if you already have it built.

From reading your comments, you won't notice a difference from the SSD to the ICON or the Q. Get the SSD. I have played with all 3 subs before.

To tell you the truth, you could stick with the SA sub and rebuild the box for smoother sound.

I havent built the box yet.

And i have SA-12s and i wanna try a 15 out so i might as well explore other brands outside of sundown. The sound is smooth right now and to my liking, again i dont have a shit setup right now or anything, just wanting to change it up a bit, build a new box, and explore other subs in the world of car audio.

Fi builds SSA woofers. They are both great American companies. If the budget is your most important factor go with the SSD. You won't be disappointed and probably wouldn't notice a difference in SQ terms.

Thanks man for the help, and everyone else lol. I think I AM A go for the SSD and just go all out on the box and make up for SQ that way.

Me...

Thats mostly why im even changing my setup at all, to build another box lol.

Additional info: Im MOST LIKELY going to keep my Hifonics 1200w @ 1 ohm amp to push whatever i get so keep that in mind...

Ok well thats very close to the price of a FI Q, would the ICON still outweigh the Q in terms of quality?

If you are truly looking for a SQ sub the Icon would be a better pick over the SSD. Fi's SQ woofer is the Q.

I'm aware that SQ would improve with the ICON over the SSD, but the dilemma is whether or not it is THAT much of a difference to spend the extra money for that quality. Like would the difference in sound quality of the subs be so noticeable that spending the extra money is a must?

And any idea on what a ICON 15" runs for price wise?

i am definitely building the box

As far as pricing goes, from the FI website:

FI SSD 15": $224

FI Q 15": $304

For the SSA DCON and ICON idk pricing, maybe someone on here does?

Yea i would like I know the advantage of going for an icon over the ssd. Then again if I raise my budget and to that of the icon, would an fi q fall in that price range and would that be a better choice than the icon?

Oh damn idk why i was thinking the opposite lol.

As far as DCON vs. SSD goes, the rms difference is really swaying me towards the SSD. Any reason i shouldnt have my mind changed on that factor?

Thats another plus on the FI SSD, american built lol.

And what you mean where am i building the box?

I'm liking the FI SSD 15" im probably gunna go with that one...

Electrical engineering work lol.

Whats you're system consist of?
