i hit between 151 and 160.8 depends on temp out side how much battery i have and lol the tearmlab

what vehicle is this

 

[Mattd0344 10+ year member]

It's an older Accord. Box is probably 3.8 or 4 cubes. It peaks at maybe 45 hz or so, I can't remember exactly.

for two 12" nightshades??? i know bigger boxes are more efficient but i thought they did better in smaller boxes?

I thought the sub I'm using right now would be power hungry, being an Rl-p motor with Fi softparts. I just threw it in for the hell of it and it ended up sounding really nice IB'd.
the sub is only seeing one channel of my 4channel amp (250w @ 2ohms), -7dB on the xover, and 5/15 sublevel

and it still gets loud. It's a mystery to me. I don't know why it works so well, but I like it.

I just noticed it has Fi soft parts. The Rl-P is actually a popular driver for home IB. Many on infinitely baffled have used it. I don't know what changes using the Fi parts has done though.

u hit between 150 and 160 depending on the temp outside....

i know temp plays a role but not that big of one.

Loudaccent Keep your eye out round end of June for a 2X TeamNorthEast and 2X Dbdrag event! Just looking to finalize the date!

Here are some vids of a team mate's car. It's an '06 Nissan Altima. The setup consists of 2 Rockford Fosgate T1 15s powered by a Sundown Audio prototype saz-2000d. The box is 6ft net volume w/ four 4" ports tuned to 33hz subs up ports forward. It hits 148.6s @ 40hz sealed on the TL mic on the windshield.

pics of the prototype??????

nice can we see the box?

 

[jdmferio13 10+ year member]

yeah see the box are those in trunk

[roarzorz 10+ year member]

One of these days I'm gonna convince him to put an saz-3000d on them. I'm 100% positive it will do 150+ legal with the added power.

 

[jdmferio13 10+ year member]

thats 6 cubbes what are the specs of box and has he tried those in trunk any other ways is that the loudest setup the way he has it.

 

[thorshammer1 10+ year member]

Nice! x2 on the pics!

 

[thorshammer1 10+ year member]

late post^^

Swweet pics! Porting into the cabin. Very nice. How does it sound like that? Proto 2K looks nice!

Yes that box is 6ft net volume w/ four 4" ports tuned to 33hz. It's the loudest we've tried so far. What works for him might not work for you though.

They sound great. He has a pair of the new Sundown Audio Z15 subs on pre-order to swap into place of the T1s. Then we'll be putting some extra power into the car. We had strapped a pair of saz-1500s in there but the T1s didn't last long with that much power. They did well though for only being 600watt rms subs but now he's skeptical about putting any real power into his new set of T1s. The Z15s though are rated 1000watts rms but have been tested with over 3kwatts repeatedly wiout any coil damage at all. There aren't any concerns with running a pair of saz-3000s on them for burps.

Here's a vid of a single sub setup in that car sub forward ports to the driver's side. This box was 3ft net volume w/ two 4" ports tuned to 33hz. It hit a 143.5db @ 40hz with a Kicker cvr 15 powered by a Sundown saz-1500d at maybe half power.




I don't know if anyone has noticed but the port area in these setups is on the low side. It truly needs about 50% more port area. In the single 15" sub setup using the exact same box in the vid above I saw a 0.5db gain by adding a 3rd 4" port. The problem in this car though is it likes extremely low tuning and hits it's best #'s tuned down to 32-33hz. With six 4" ports for the two 15" setup they would need to be 30" long to keep the same tuning which is impossible in this car. We're throwing aroung new designs to get the port area where it needs to be because in theory there could be a full 1db gain just by giving it an adequate amount.
