I like the idea....After all even the seasoned vets don't know it all...

I think it would also be interesting to hear peoples results from testing with different cars,subs,enclosure designs...I know I have a lot of box design ideas always running in my head and I'm always wondering which would work in such and such a car...

I've been in this going on 3 yrs now and I find I'm learning something new on a daily basis even in the offseason....

Great idea,Man.....Let the sharing begin!!
Aren't you the guy that won't tell us what you want to get in contact with Pioneer for because you want to keep it a secret?

You others to share, but keep secrets to yourself. Hypocrit. [img]tongue.gif[/img]


Anywyas.. I haven't started building yet for next season, so I really don't have anything to add just yet. [img]graemlins/thumb.gif[/img]
</font>[/QUOTE]Youre sort of right....But I also said that once I got going in it to see what I could do on my own,I would let everyone know whats what....I guess in a manner of speaking,yeah, I'm being a hypocrite, but its only help myself expand my mind and learning....

I dont know if that makes sense or not,but thats what it comes down too...Alot of guys on here have huge amounts of experience and knowledge thru trail and error...thats what I want!!

that is me for sure....there is no way that i could really work on my car during the off season - weather, school, money...all play factors in limiting my spl time. but as soon as the snow melts....look out!!!

I do understand that people have not started building yet but on the other hand niether have alot of the experienced people. I know if we decide to build a car this year it will be built after hours and on Sundays, this will leave not much if anytime to help others. What I will suggest is that people that will be building this year start doing research now!!! If you are going to be in street classes post what kind of car,equipment, and enclosures that you have been thinking about trying, maybe one of the street guys or someone else has already tried that design and can give you some insight into it or can suggest something. If you are in Super Street you really should be building by now, our last SS 1-2 took 8 months of 4 nights a week and all day on sundays and then it was cram time the night before Audiothunder in 2003 and that sucks. The biggest peice of advice I can give is if you think that it will take a week clear 2 instead. The finished product will never be what it was supposed to.

Fine then... help me out. I've got equipment you should be familiar with.

Stock 1 in IASCA. (2 amps, 2 batts, 2 10's)

I'm running 2 of the Jonah Lomu amps. Modified to put out like 3k. (stable down to 2 Ohms)

1995 Mazda 323 with a Hawker 2150 under the hood and a 200 amp alt.

For subs... I honestly haven't decided yet. I was looking at either 2 of the Powerplant 10's or 1 of the Competition 12's.

If not then I'll go with something other than Fusion. I've got a great deal on Fusion equipment so I'll probably be going mostly with that.

The HU I'm using is a lower end Panasonic but it has 2 sets of 2.5v pre-outs.

All last season I was running a 12" Inhuman in a modified CRX box. (cut off about 9" in depth and made it 2-3" higher) rounded corners... 2 x 4" aeroports..

I tried a version of the Panda box at Finals with 2 DD subs. They didn't do very well but I think that's because the box was too small.

My best score was a 149.4 on the AC SPL190 sensor.

So... any suggestions?

I appologize upfront...I dont make a habbit of knocking equipment...go back to your DD's the power plants( from experience) will not hold up for SPL
lack of xmax...and hopefully by now they have also corrected their glue problem..they kept falling apart at the 3point..spider cone and coil

but a 323 good start.... PM me with dimentions of the cargo area max dimentions and also distance from from hatch to centre of windshield at dashboard

</font>[/QUOTE]Don't worry man.. I know that the Powerplants wont be the best. I haven't bought any yet... right now it's just something I'm considering.

If I try them and they don't work out I'll just be sure to get something else that can take a beating.

For box size I have the following to use in the hatch area:
38" wide x 17" deep x 16" high

I'll get you the distance from the hatch to the windshield tomorrow.. it's a bit late now

Sorry about the length here...And yes I am a dirty American, but am no different from ya'll. You scratch my back and I scratch yours eh? lol

To all the pros, how much will rounding all the corners and such in the box help?

I've been contemplating this for my setup. I didn't know about it when I build my box...I don't really want to do a lot of heavy mods though because the box is 9 cubes and 1.5 thick...bolted to the frame in 12 places, ect.ect. (hard to mess with by myself)

If it helps, I'm running 2 TC Sounds LMT 15" subs off a JBL BPx2200.1 (getting another soon) at 2 ohms (2200 Wrms). The HU is Alpine CDA-9835. I've only got the stock Alt (175A) and an additional Stinger SPV-44 yellow top battery. All this is in a 1997 F-150 ext cab with the subs inverted and facing up along with the port.

I figured that by rounding the corners in the box, it would reduce some airspace and also give me a bit higher tuning freq. (Box is tuned way too low to hit high on the mic---like 25 Hz//but you should see/hear the lows...) Its almost impossible for me to modify the port...I didn't take all this into consideration during the planning process...

help me out and give me a few ideas. (please no walls-not yet-its still a daily driver)
Also I think it may be illegal in Texas to wall it off...hmm..not sure..I'll have to check that out.

anywho...thanks a lot
