Look for sD in the ts parameters.

Anything below 200 hz should be ok, but most capable midbass drivers are going to want more than 50w each to shine.

I want a set. Has anyone measured their exact depth? I seem to remember hearing that they were deeper than the specs suggested.

That was me with the small pickup. Any ideas on what I should do then to achieve the low, loud bass that I'm looking for? For example: tune lower or higher than normal, build a bigger or smaller enclosure than recommended by the manufacturer, bigger port or smaller port? Let me clarify one thing. I'm not an spl guy, never have been, never will be. Consequently, I have never tried what it sounds like you are try to do. I am more interested in a somewhat flat, predictable low end response and have spent much more time studying the ways to achieve this goal. That being said, you're not alone. Visit any audio forum and do a little searching and you'll find a number of people who are not getting the response they want out of their trucks. It would be fairly easy to get a good low end response by using a large enclosure and tuning low, but then you're bottom end will be bloated and your fundamental frequencies (40hz-80hz) will suffer. If I were to try to build a ported enclosure for a pickup I'd build it towards the smaller end of the size spectrum and tune it a couple of clicks higher than I would in a larger vehicle... but again, I'm not an expert on the subject.

I'm just saying that a guy with a small pickup would have to design his enclosure differently than a guy with a minivan or a large SUV. Put two identically tuned boxes into two totaly differnt vehicles and you have completely different results. The enclosure that works well in my truck isn't going to fare so well in a school bus... even if it is well designed for the sub that is going into it. An enclosure should be built with the vehicles charecteristics in mind, just as much, if not more so, than the sub manufacturers recommendations for their sub.

Well. I guess you can get low in any vehicle, but the amount of output you can achieve down low is vehicle dependant to a large degree.

3 pages and nobodys mentioned the enclosure for the enclosure. Believe it or not, the size of the car plays a very big role in determining how low you can get, IMO.

I' ll share what I consider to be one of the easiest ways to do your a pillars. Make a basic template to ensure both sides look the same... Mark your spot... Next find a piece of PVC pipe just large enough to mount the tweeters in and purchase a hole saw the size of the outside dimension of the pipe. Tear in... After aiming the tweeters in your car, epoxy them in place, then fill in around the pipe with a two part epoxy filler... Once you've applied enough filler, simply sand evenly and wrap it in grill cloth. When you're done, you'll have something like this... At this point, just cut out the cloth for the tweeter and place it in the a pillar with a little hot melt glue. I hope this helps. It's actually a lot easier than it seems. This was my first attempt at anything like this and it turned out pretty well.
