U should be a english teacher.(Smart ass)m don't read the thread if u dnt like it. Aint nobody forcing u to read it

Something isn't right here, well a few things actually. He said he had to have his sub "REINSTALLED". Shouldn't you be able to screw a sub into a box by yourself. Is that a prefab box, sealed? I've got 3- 88120 ti dvc subs and they have over 3 inches of excursion and I use most of it with 1,000 rms watts on 1 sub. Are the massive audio amps that bad?

More information or FLAME ON!!!!

You're kicking some serious ass there Sir-Lance !!!! Enclosure looks damn good. Keep up the great work, you'll be hammering before you know it.

Is it me or does it sound like the woofer is bottoming out? Is the ssf set high enough? Maybe it's just the mic, but that popping noise doesn't sound right.

I would like to know if you see any potential problems with mounting a peerless 6.5" mid bass speaker "in" the door pocket of my 2000 ranger. I currently have jl audio xr 5 x 7's (coaxial) in the stock location in my doors. They image like crap ( no real surprise there, a lot of the time it's behind my head or at my feet ). I've been playing with some T.B. W3's as well as some FR 88 ex's on the dash by the a pillars. I like the sound of the fr88's and am going to try going without tweeters. I also bought 2 peerless 6.5" sls mid bass (830946), which I plan to put in the stock door location (red square in pic) to see if like them. If I do, I plan to get 2 more 6.5's and mount them behind the door pocket ( green square in the picture ). The black "inner" door pocket will be removed from the door panel and should provide clearance for the 6.5" mid. I plan to cross the mid no higher than 250 - 300 Hz. So my question is do you think it will sound correct or not being "in" the door pocket? I don't want to have to fiberglass anything on the doors (been there done that, don't have the time now). I have deadened the doors already ( entire truck )and will make a 1/4" thick steel panel to mount the speakers on, then weld them in the doors so they are as solid as I can make them. They will be driven by a sundown 125.2 in stereo (2 ohm) and hopefully play in the 70 - 250 range with some authority. Your thought's will be greatly appreciated.

There are allot of better box designers/builders on this site then I. I will state my experience with the sa-8's. The box I built to house 4 sa8' was too big in my opinion for my goals, 3.2 c.f. net. (.8 per sub) I like tight sound and somewhat flatter response and let cabin gain do the rest. The above box was tuned to 32 hz. with a 4-1/2" x 11-3/4" port. I seemed to get no output from them until ~ 45hz.- port tuning. This was very loud around tuning, but didn't sound right at all, way to peaky for me. I wound up pulling the box out after 3 or 4 days. I had a .75 c.f. box tuned to 32hz. as well, so I inverted the sa8's (2 of them) and found the response to be flatter. I now had some output at 60hz.. The output was on a gradual rise til tuning, not a spike/peak at tuning. This was much more to my liking, but with much less output across the pass band. The sa-8's were much more musical in a small box to me. You stated you wanted more SQ than SPL. I don't think I'd go larger then .4-.6 c.f. per woofer unless you've got some great mid bass already. I'd ask the box size question again with a particular freq. range and type of response curve you're looking to achieve, flatter or peaky, if I were you. Good luck.

Thanks for the response to my questions and guidance along the way, now it's all on me to pull it together. I think I understand this statement, but perhaps it's the wording that has me a little puzzled. Are you stating to find the above location, then place the mids there? I understand the equidistant/equal angle, it's the underlined part that I'm unsure of what you're referring to. I'm assuming the mids, but perhaps the way you've worded it, it sounds as if you're referencing something else. Thanks very much ///M5 !!! I was looking back at J-raodtatts build log and the grills he used on his widebanders. I believe you referred to his 89ex's as mid's , I think I understand the underlined portion of the quote now, my 88's > mids. Thanks again ///M5 !

I can tell you from experience/mistake the 2000d will be very grumpy at .5 ohm.

Well, Tues. was a no go. Unexpected Dr. appointment, for my mom. Today I went out and put the 88's on the dash wired up the 300/2 and ran some temporary power/ground wires for the eclipse AV8533. I fired everything up and started adjusting. Holy Crap!! It's like cheating. It took about 1ms. of delay on the drivers side 88 to put the image in front and just to the right of me. So I started to look for a place to mount the Friggin HUGE brain for this head unit, it's longer then the 300/2 or the sax 125.2 and almost as wide. I found a good spot and started to remove the old HX-D10 and install the 8533. I believe the wires are long enough to mount the brain in the house and still be able to drive around the block. After everything was installed I put the 125.2 and the 300/2 in the pass. seat wire them up and started to listen again. I had only the 88's playing and found aiming them at the dome light was the best spot so far. I upped the crossover to ~220 hz. and 1ms. delay to the drivers side seems to be my sweet spot. I'm surprised that the top end of the 88's seem smoother than with hx-d10. I brought the sls's up to match the 88's and started to explore TA with all four speakers. I also upped the crossover on the sls's to ~200hz. or so and raised the sub/infrasonic filter to ~ 50 hz.. It sounds pretty friggin amazing! Right now the sls's are about 6"-8" from the door panel, the drivers side woofer face is almost even with the center of the steering wheel facing the opposite side of the truck. As I played with the TA on the sls's it didn't seem to effect the sound much, if any, at all. The stage is above the dash just below my eyes outside the base of the windshield, no longer in my face. The width is just inside the a pillars at the moment. I will try aiming the 88's more on Friday and this weekend to improve the width if possible in these locations. Please give my an educated guess on the following 2 questions. I understand that there are allot of variables that will effect the outcome. Do you think TA will have more of an effect once the sls's are mounted in the door, at the boundaries of the vehicle? I assume width and depth are more an outcome of aiming then processing. Would you agree or disagree?

I have not received the DC 28's yet. I'll put the eclipse av8533 in the truck Tues. and post back on the 88's after. I'm not against an active 3-way front stage. That is the end goal if necessary, but learning a 2-way first for now. I have the a-pillars/ dash/ sail panels and the doors as potential places for speakers. Would you recommend anything different for the locations I'm using now, for a 2-way? It sounds to me that you believe I have a solid system that I need to work with now. By this spring I should have the pioneer p99rs installed and have all the processing I need to achieve my future goals, a smile on my face every time I turn the system on..

The system in my truck right now is jl 5x7's in the doors and an eclipse sub behind me, with #1 jl300/2 and sundown 2000D driving them. I don't have any of the above on when listening to the 88's/sls's. I am putting the amps in the pass. seat ( for the 88's/sls') to be able to adjust them easily ( #2 300/2 and 125.2). These amps are not part of the jl/eclipse system in the truck. I can reach both 88's on the dash as well as the amps form the drivers seat to make any adjustments. Once I'm able to get the 88's to sound and image well I'll remove the 5x7's from the door and mount the sls's in the door. I don't want to go without a "backup" system until I've made some progress with the 88's and know it what I'm doing will be worth the effort. I ordered the tweeters before you came into this thread and was considering a low crossed tweeter and the exodus anarchy's or another mid. The Dayton tweeter got decent reviews and was only $10.00 so I thought it would help me with which direction I will wind up going with. After yesterday's listening impressions, I believe the top end of the 88 is a little strained/ragged and will probably require a tweeter up top. I know I can't fit a large format tweeter and the 88 on the dash at the same time.
