SPLScion

SS's site is working fine for me. Sent you a pm to help you with the links, if they still don't work let me know. BTW I have heard quite a few BTL subs and they sound great IMO!

X2 welcome

Def. a more mature audio forum here, real top notch people with tons of knowledge. Welcome, hope you like it as much as I do!

Welcome, I've joined tons of forums but this one is by far the best, sure you will agree.

LMFAO! That's awsome!

hey whats up what kind ofsubs do you run in your excursion im currently going about buying 4 apxx18's have u ever used them By excursion we are refering to the subwoofer's excursion not the truck, he has these 10's in a trunked vehicle. :-)

hard for me to tell in that pic but it looks like your saying the FETs are burnt out. I wouldn't be able to say of you can fix them as I don't know your skill set, but if you can't I'd send it to db-r he does great work, has great customer service and he usually sends them out stronger then the day they were built. Good luck either way.

Nice, maybe I'll try to make this if work permits. I hear from people I respect that your a serious competetor, best of luck at the 3X. Hopefully I'll get to make it and meet ya.

sick a** excursion! Are you the guy with the 2 5K atomics? If so I've heard about you, I think you will be base racing a friend of mine in 149.9 soon Dave in a blue Tuscon.

5 days till the 2nd Aftershock event! Can't wait for my home coming, will be fun to return to the comp. I discovered NESPL at, plus I need to certify my 145+.

To amplify my front stage I would buy something high quality like a any thing Zed, Sundown sax or a Soundstream reference, or perhaps an Alpine. These can be found at great prices if you search hard, esp. if you plan to go active. I am an SPL guy tho, so others I am sure are more qualified to answer you but you won't regret getting the higher quality amp. I dont have a ton of experience with Hifonics for anything but mono amps but they dont compair to the ones I mentioned IMHO.

wow thats a huge gain pushing on (and off) the sunroof! a bigger gain then I get when people do the same on my hatch wow. Did you test with only the center console open and then closed, also did you open just the top half of it or both sections of it open? for non-Tc pwners reading this our cars have 2 compartments for the center console. I forgot that you run outlaw shizzzon :-) i think i am going to run the no wall class next season. that damn window line rule is kinda forcing me to, cuz i prefer at least 15" subs and multiples of 'em and large enclosures most of the time anyways.

That looks sexy! Def. looking forward to seeing some specs and some more pics of the motor.

not guesstimate, he used both measurements and did the math so I'll prob. smoke the amps, they aren't 1 ohm stable? bummer. damn your top 3 designs are nowhere near what I got doh! back to the drawing board I guess, and time to do some shopping.

its funny you say that cuz its what my buddy w/ the meter has, and every time he tells me what I am hitting and I roll through the TL it is exactly right, down to like a 10th! I will be filling that area I call my cavern with the foam too, thanks for the tip.

I figured that with a wall they didnt affect you, but for me they were horrifying, considering my setup, subs up prts back, thats a major loading area for me, so it was killing me. What I want to know is why the buddies holding my hatch during spl runs never noticed the soundwaves slamming their feet and ankles. WTG guys <insert golf clap here>

there is one on each side and they vent directly to the outside of the vehicle, their big too dunno how I never noticed them before. Gotta love duct tape tho, if ya cant duc... you know the rest right.

for example, I finally got some deadening for my TC and when going to install it on the rear 1/4 panels I found this!

I've got 2 sub amps one to each sub, wired down to 1 ohm (dual 2 ohm VC's). Each amp has a rise of .8 - .9 ohms so each amp is seing a load of 1.8-1.9 ohms. They are rated at 600w @ 2 ohms and 900w @ 1 ohm. the clamped measurement yesterday was 650 to each sub. the meter is placed on my windshield, passenger side I haven't measured it but I have a little circular sticker to the placement is the same every time. Its where db-drags place it aout cuz NESPL uses db-drag style classes and and rules including placement. I'll measure it tom. suring the day cuz there is a sick storm going on outside right now, mad lightening and thunder. The loudest score I have hit on a tone is exactly one db lower then on music so 144.2 (kinda weird but I have been testing with and for music because of my class requirement, music only, all year) your scores own me lol but I am working on it!

one reason to run 2 smaller batteries instead of one big one is because of rules in different SPL organizations. For example: in the league I compete the NESPL, my class has a battery size limit of 650 cubic inches, next season I will be jumping up in class and will be allowed 800 cubic inches.

back in the day about 1996, I had 2 soundstream SPL-160's in a massive ported box, some one tried to steal it and coldn't lift it lol. So I can only assume out of anger or spite they pushed in both dust caps. I was horrified at 1st but then at the next comp I didn't drop even a tenth on the meter and actually won the comp with the ugly dented dust caps. However a month ago my buddy Mike from Team Renots has been blowing the dustcaps off his 15 (he has 4 15's walled in a olds. cutlass, believe they are T3 tsns I know they are all customed to the hilt) and lost on the meter. Of course he is hitting 160's dunno if that is a sign something else is wrong or a coincedence or what but fig. it was worth mentioning.

I forgot a few things, all the tests were at idle which in a TC is about 600 rpm and with the A/C on, cuz I didn't have the heart to over heat my friend. I also found a neat trick, after a couple hours it got pretty hot, I cranked on the A/C max defrost and cooled the area around the meter. I left it on for maybe 20 secs or so, then I turned it off and let my volots come back up the 2/10ths it had dropped and hit the mic with everything I had, I gained .2-.3 or so!!! wont work in cool weather perhaps but on a hot summer day... helped alot!

try out the last song on that cd! lol BME click is the best. hmm, will have to go outside and try it, i haven't made it to the end of the cd yet cuz so many hit hard, do you know what freq. the song is (for the most part i mean)

Not owning a meter I have not gotten to do much testing. My SPL comp runs have been as much for testing purposes as for fun. I have done 3 testing sessions not in comps. and the 1st 2 were in between comp runs for 20-30 mins each and then yesterday I finally got a chance to do some rigoris testing for a few hours. Here's what I learned helps my TC get louder: 1. a. Passenger seat all the way forward as if some one was getting in back seat of my 2 door, a funny thought cuz I made my car a 2 seater with a massive enclosure. b. The back of the seat all the way forward. I have a pic. of this if any1 is having a hard time visualizing, but its a common practice with db-draggers to do this and it makes a huge difference on the mic. 2. Sun visor down, almost verticle. The point of this in conjunction with the seat being forward is to make a condensed and aimed pathway to the meter, and step 1 + 2 adds about 2 db's to my score! thats alot imo! 3. Glove box OPEN this gives me .2 db's every time. 4. Vents on dash closed, this gains me .1 db to .2 db 5. Sunroof shade closed (on both sunroofs) this gains me .2 every time 6. Enclosure kitty cornered with the ports aimed more to drivers side, if you look at my avatar you can get a feel for what that looks like. I gained over a db from this. 7. Port 6.5 inches from back of hatch yeilded the best reluts making a 1 db gain for me from having it further away. I need to lengthen my wires to the box so it can go back further then test, cuz it was as far as they would reach atm, so who knows, 6 " or less might gain me more... 8. My dash score is exactly 1 db higher at the kick over the legal position on the windshield. The rest of my testing invloved freq. testing song testing (cuz this year my class requires me to play only music) and settings adjustment. Apparently my DMM is junk cuz my amps were not gain matched properly one amp was 3 detent clicks off lol. Apparently Kenwood HU's are very touchy when it comes to SPL applications. One click too high on volume or subwoofer level throws off my score by a whole db or more! My friend told me he had a Kenwood HU, albeit a different model and had the same prob., so it required a ton of testing to find the sweet spot for all of the settings on the HU. I tested my box rise, 1 ohm each sub, and clamp tested my amps power and found I was getting rated power but no where near enough which I obv knew already. I am giving my subs only 1300 watts which explains why I am so quiet! My friend with the meter, who also happens to be my box designer/builder and holds a few WR's tells me that I am pretty loud for so few watts. He says that a 145.2 (after a long hot day of testing w/ hot VC's) is respectable, but I am an SPL guy, it will NEVER be loud enough! I really wish there was a way to make my amp see a true ohm load of 1 ohm, but I suppose I'll just have to get a monster amp and power through my box rise. For the record I know a 1 ohm rise is good and most have much more then this, just frustrating cuz I am in a class this year that limits the amp to 2000w rated, not clamped. The day before this testing session I put in some deadening on the rear 1/4 panels, while doing this I found some huge azz vents on the panel that vents to the outside. Shizzzon, do you know what I am talking about? I can post a pic if any1 needs. I taped them off then put foam in front of them and taped over that, its a short term fix but I will be thinking about a long term solution non-stop. What did you do about these shizzon? I fig. you may have done nothing cuz your walled off so it would affect you less but worth asking ya :-) When replacing the little rear tail light access panel I discovered that there was a leak in the metal right above the tail light on passenger side, so I taped that up 4 the short term. Will have to fiberglass or bondo that from inside soon. I duct taped around my sunroof and it def. helped seal it even though I only used 2 strips of it on each side. Shizzzon what did you do about how hollow the rear 1/4's are (really I mean the "c" pillars. My friend suggested I use expanding foam to pack it tight and seal it up, what do you think about this? OK, thats all I can remember for now, but I'll say this before ending: Testing is the single most important thing I have done to get loud. It has given me my largest gains, and at one point I went from an 800w amp to 1800w and yet gained less then from a few short testing sessions. When all was said and done testing has gained me over 5 db's! for free, not including my comp runs which I consider testing sessions in their own right. I guess I'll say one more thing before ending, a huge Thank You to SSA, its mods. who are very informed people on many subjects and SSA members for helping me (even when ya didn't know it) and educating me. A special thanks to shizzzon for all his posts, he always posts insane testing/result posts which help me in particlular having the same car and many of the same goals, plus his other posts get my brain thinking. Hope this post helps some one some where, if not at least I'll have it for myself :-)Any questions feel free to ask. -Bill

NICE you decided to wall! Been hoping you'd give in and do it up, will take a ton of testing but you'll finally get to unleash the potential of your Van. I am getting a meter this off season, we will have to do a bunch of testing. Check out shizzons build log for some ideas and a show of the testing needed. Will be fun. It will be a brutal class for sure next year, but I know you are willing to put in the time it will require to do it right. I also have some links of a bunch of vans walled to give ya some idea's if you want I can shoot you them. Walls that you can walk behind through the port and what not, sick stuff.
