no reelfish Just read that, was that the box with the 2 Fi Q 18s on S10 forum? Yes

no reelfish

x2 Looks like its beating that truck up. Very nice. I sent you a pm a few days ago, lol

I would do 6-7cubes with around 100sq in of port for one 18. You current box is all jacked up.

That car is completely insane!! After being around comps for a few weeks I have seen what a 59 looks like and I can tell you I do not want to be sitting in it!! Impressive

I would love to receive my sub before finals!!!! But today mine says awaiting shipment. I better not get excited, then mine will take 2 months to get here. LoL

Are the Ib3's not a option

4 Xcons on a 5500 would sound awesome!!

If you were local I would hook you up, but with you being in NY I would look for someone local. There may be a few guys on here that are up that way. I also think maybe DC Creations would ship you one, but unsure. Look in the Vendor section here

May tune this one alittle higher at 32, damn cant decide. Was also looking to see if I had room for a 4th order but I think a pure wall would be louder..... Gonna be getting wood tomorrow and maybe start this weekend. Guess I need to start a new build log, lol

My 89 Saleen. Never a system in it though, hell I didnt even have a head unit, lol. Car made about 400rwhp on motor only (347, etc etc) http://s55.photobucket.com/albums/g129/Heavylifter/?action=view&current=100_4011.mp4 Sorry for the Off topic post..............

I HIGHLY doubt that. It has to be built

To focus on the lows you will want ported. Big output requires more space and cone area than you have the space for. Some trucks sound best with port on the side. Find another shop.

If the volume goes up to 62 like it does on my Pioneer then turn the volume up to 52. If not turn the volume up to 75%. Then put it on the hardest hitting song you have and slowly turn the gain knob up until you hear slight distortion then back it down till that is gone and there you go. This would even be better to do it with a test tone at say 45-50hz. If that seems too difficult just set the gain to 12 o'clock, with bass boost off and listen for any distortion. Just be smart and listen for any funny sounds, its not difficult to set the gain by ear.

Every FI sub I have bought took right at 30 days to get. I hear shipping has sped up some. Hoping for 2.5 - 3 weeks. but either way its worth it.

Shyt.. That run-on sentence mad it hard to see... Thanks for that Swift... I noticed the T/S there but didn't see that mixed in.... Lifesaver! Sorry it doesnt read that way on the site, but if you click on the actual sub listing the recommendations are at the bottom in a god layout. Confused me at first too with the quick look and took time for me to find it as well. Maybe if by clicking the picture or the subject matter about the sub it would pull up the same detail it would be easier for the shopper. But the site is a HUGE improvement as before.

JK, hahaha

Because I ran a Q 15 and loved it, then stepped up to two Q 18's and loved those aswell. Even the day I ordered the Q's I wish I had stepped up and bought the SP4's. So I quickly sold those and bought what I wanted. With the 4in vc, low fs, high Xmax and big power handling I knew this is what I wanted. The Sp4's sound just as good as the Q line but doing in a MUCH stronger fashion. These subs are low end monsters and that was my goal. My truck does the same db at 28hz as it does at 40hz and will peak around 34, all within a 1db range

I will, I doubt they would get here before then. If for some long shot reason they get here before then I will have the wall in. Whats nice is this will be built next week in my garage. When the sub arrives I will just swap it all over and add the beauty panel. I just need to go ahead and do more runs of 2/0 so Im ready for the extra amp when I buy one. Rear window seal is already going now and if I play it while its raining water comes in. Its pretty mean to the truck now.

After thinking about it two 5500's would be down right nasty I think.

I would do 4.5cu tuned at 30hz. Quit worrying about the amp size when decided on how big to make the box. You said you want to play high 20's with authority. Tune low and make the box on the larger side of the recommended specs if you have the room. Be careful with a DD-1. Easy to mess your subs up if the amp puts more power than the subs can handle.

Every car I have heard with sub firing up in a trunk sounded like ass. Two 12's will do better in the truck rear firing than one 15 firing up. What made you not like the SA12's? Probably was the install. T

Email FI directly to answer the differences that may or may not be with your sub versus new. Unless Shawn sees this thread. About the amps just make sure you can either strap 2 of the same amps or just buy a single amp to power both. 4cu will be ok for both 12's if that is after all displacement. My experience with the Q is that they like a enclosure on the larger side.

Dont replace, just add to it. You mention replacing your stock 4 gauge. Just add a run of 1/0 to what you already have.
