Much depends on the volume you want to play at. Better to go bigger than not have enough and strain your equipment. A suburban or extended cab truck cab will be a much bigger space to fill than a compact car trunk, no reason to compare the two. If you drive with the windows down on the highway offer yourself enough volume to overcome the road noise.

Normally a subwoofer amp may shut down due to thermal protection (keeps the amplifier from overheating and destroying itself). Otherwise its possible if your sub has an auto on function it may not have been sent enough power to turn on the auto on function. Also possible the amp may be malfunctioning but its best to rule out other possible causes first as mentioned above.

The woodgrain is beauteous, guitar is a classic. This should sell quickly.

Why not just brace the horn mouth ? 3/4" plywood will add alot of weight, you could just use 1/4" sheet & band the front with matching veneer. I like option #3, you can then add a riser to match the Belle look. A set of rubber feet will keep the top from sliding around or if you still feel the need to attach a few small circles of Velcro will keep things secure. You can always screw it together too.

I use flush trim router bits regularly with good results. As long as the bearing path for the bit is straight and smooth it would be my choice over a circular saw. If you do go the circular saw method be sure you have a sharp blade & set the depth properly.

OBD II was a huge leap forward for diagnostic capability + having to use different harness connections on OBD 1 systems was a headache.

Likes don't come free around here. Errrr wait, maybe they do.

The days are gone where you just needed a oscilloscope, vacuum gauge, dwell meter & timing light with basic hand tools to tune up a car. I don't miss installing points or rebuilding carbeurators myself.

I prefer Snyder's honey mustard and onion pretzel pieces myself. Plain pretzels are kinda boring but i do like the big salty soft ones hot out of the oven.

The codes are only a piece of the puzzle. It's the data logging, both memory and in real time, that are useful at getting to root cause. Codes are just general information on where the problem may lie, data can often help but most would not know what they were looking at anyways. I spent 2-3 months out of the year in GM training school just to keep up with yearly changes. Think the backyard mechanic could get by with limited or no training ? I think not. Watching sensor data in real time shows what the engine and emission systems are doing. It can help in some situations. The ECM processing hardware alone (sensors, harnessing, ECMs, etc) add about $3K to the cost of a vehicle. Not to mention most of these parts are OEM only. I'd like to have access to it since I paid for it. You pay for the vehicle but manufactures do not want weekend mechanics working on their own vehicles. I don't make the rules but i agree more harm than good can be done by a uneducated tinkerer.

Some cars can access the codes & much more information by way of dashboard cluster or info screen but most would not know what to do with the code and end up just throwing parts at it anyways.

I add a horseradish flavored pickle as a top of glass garnish myself.

I have a Table Tuba to bring along if the room is available for me and my folded horn.

The Tuba 30 should have no problem keeping up with your KPT- 200 pair, probably distort your mains before you hear any stress from the subwoofer. Looks like a great project. What made you choose the Tuba 30 over the Table Tuba ? A double 8" Table Tuba would hit lower notes and give more than enough volume.

Thank you very much. Just hungout with family today. Another year passed by too quickly.

SVS subs are good but in no way a substitute for the effortless sound of a horn loaded subwoofer. That's what I was waiting to hear jason... but you never got back to me via email... Sent you back a reply to your PM the same day, feel free to E-Mail me anytime. jasonstr1969@yahoo.com

My advice is find the nearest local authorized Denon repair center and have them do the repair, they should know your receiver better than most and perform any other updates if needed as well. I think shipping delicate electronics is not worth the risk especially if they are of value to you.

Apology not necessary, just buy the participants a good lunch and a couple of beers. I have no problem manning up and admitting I'm wrong when I'm wrong and thought an apology would be a nice touch. The $50 would be used for grub & beer for the participants.

3 pairs of Dayton B652 bookshelf speakers. $179.40 ($59.80 pair) 1- 12" Dayton Subwoofer--------------------------$129.00 Total-----------------------------------------------------$308.40

The woofers are good and the tweeters are highly rated, i would have not recommended them if i thought they were not an upgrade to the other suggestions.

C'mon Mike. Don't be so defensive. Everyone knows it's all about location where leaks are concerned. Drilling a hole in the tail pipe of an automobile is a lot different than drilling a hole in the head gasket. So where is the hole the most problematic? If we're talking a 1/4" mounting bolt removed from a 15" driver, then the maximum influence that can have on the output would be around -0.003dB. The whistling it makes will be far more noticeable. It is not uncommon for me to only install 4 bolts when tracking down other real problems and the response plots overlay quite nicely. A 1/4" hole isn't going to explain a +/-6dB issue. The fact that a horn will load to within +/-3dB with the walls of the horn just laying against each other is telling of the sensitivity to this kind of thing. It happens that way because most of the wavefront doesn't even get into the corners of the horn path. The wavefronts like to be more spherically shaped. Btw, I'm not advocating that we build leaky cabinets, nor do I think it is defensive to point out false claims. A paltry $50 says you're wrong. I have a brand new tested Table Tuba with a RE Audio REX8S4 witch is very similar to the THT in design I would gladly bring over for this test. I suggest one neutral forum member be present for a witness and bet your -0.003dB estimate is very underestimated by at least 100% sounds reasonable. Anybody local neutral forum member willing to be a witness if Mike takes this challenge ? The loser also needs to apologize on this thread along with the posted results.

For ~$300 Speakers Sub Not Klipsch but much better than what you listed here. Those 3 way Sony's are not too bad, maybe you could just find more of them to complete the system.

Great analogy, i like the way you think.

I assume you're talking about conventional type subwoofers. Personally i do not recommend mixing those either due to phase issues, by adding horn loading into the mix just adds to the complications. If somebody absolutely has to blend subwoofers don't just hook them up to a plate amp and expect miracles to happen. Phase cancellation is present as is delay complications in a horn loaded design, plan for the worst and hope for the best when mixing cabinets.
