rfpcreations

i would also make the port as smooth as possible if spl is your concern, it looks like that person used some kind of texture paint.

I am going for 160+ later this summer with 4 rlp 15's.

how many cu. ft are the enclosures? looks great!

thanks for the link it does not really apply to trucks but i will probably face the subs forward, which is how i had a 15" stroker facing. as for the bx2005d the hifoncs will put out plenty of power even if they are a little over rated , so i am not getting in a debate over that topic save it for another post. , , now if anyone has any personal experience with sub placment in a truck let me know what you think about sub, port placment. thanks

i was thinking of having the subs and port facing up in a net 7 cu. box, subs on the outside and the port in the middle , but i wanted to see what you guys thought, i am powering them with 2 hifonics bx2005d amps, a zx6400 for the mids/highs (4 sets of mb quartz 6.5" reference series comps), ixos signal wires, and with plenty of clean signal from (2x) 1/3 oct. 30 band audiocontrol eqt seriesII's and i am not sure yet what ohm i will wire the subs at. as for the bx2005d amp: 2000@ 1ohm, 1300@ 2ohm. and does any one know if the bx2005d puts out true power, i have heard they are a little over-rated. any ideas welcome! my truck is a 2001 ford f-150

how many volts of signal were you actually giving the brutus, because the sould have line drivers used on them?

i really like the mb quartz rce216 6.5". don't think any one can beat the sq. plus you don't need to push full rms to get them to play at extremely high levels. i have 4 sets(pairs) in my f-150 being pushed 85 watts to each set. find them on ebay brand new for about $150 shipped.

yes 12-15" of port per 1 cu. ft. of air space. plus if you do a slot port you can always turn it into a right angle (90*) port and round all corners. the right angle bend slows velocity reducing or eliminating port noise.

don't forget hifonics amps

just starting to figure these enclosures out a little. any one got any info.

sorry no pics of the jeep , but i might be able to get a hold of some the next time i see my friend john. not really sure where he was competing when he hit that # so i will also ask him about the mic. as for the power he is using a us amp competition amp it puts out 8000 watts it was custom built for his company in ohio, the owner is a good friend of someone at us amp. the enclosure is a true comp style box that filled the entire back of the jeep and angled back 2 corners no front passenger seat using the formula (A*3=B+C+D) check link. i am sure he said the port side was tuned to 65HZ but if not close to it.http://www.audiobahn.com/Audiobahn06/image...l/SPL_Chart.pdf i will do alot of testing when i install the box. thanks for the insight on waves. by the way can someone tell me what the freq. resp of the rl-p15" is? thanks!!!!!!

as of right now i am sound dampening, already heavily dynomated but not enough for me personally. so i am covering the interior with mdf and foaming between the mdf and all metal. the back wall will be about 3"soild, needless to say i want solid. i am going to have the subs facing up behind the two front seats, i have 12.9 cu ft gross and 10.77 net cu ft of space to work with. the box will be constructed from 1.5" mdf and internally braced with 5/8" all thread. the plan is to have an interchangable port set-up for SQ and SPL for compitition. if anyone has any ideas i would like to hear them, this is the first time i have ever used soundsplinter subs. my last sub i had in this truck was a cerwin vega stroker 15"d4. the amp i am using is a modified us amp 1000 that puts out around 1800x1 @1 ohm. i am looking for stupidly insane bass!!!!!!!!

well my idea with the wall is the box will be mounted to the wall and floor (bolted that is) so the way i was thinking was the wall will just become part of the box. reinforcment if you will and prevent sound waves from going behind the enclosure and that would be a waste in spl comitition as you want as much of the sound waves working there way to the front glass. plus my friend's jeep the thinnest wall is 2.5" thick and he hit 160+db with one solo 18". so basically i am directing the waves forward. at least that is the intention. please give feed back to give some insight. the funny is i was thinking of using a concrete fiberglass mixture to fill the wall with but weight really was the issue.

ok here is the first pic i have of the wall being costructed, i will post more pics later this week so i have time to go through them. the wall is about 2.75" thick. you can also see i started on the lower shelf that will go down to the floor witch will get the same treatment. now that is what i call sound dampening.

can anyone help with inserting pics taken with a digital camera. if some one could help with this i will post some pics.
