Just ordered my (2) additional 15's. Will take pictures of the van tonight. . .

You have PM. . .

PM me your zip code, and I can get the correct person to give you a true price quote on one. Brian

It will be ok. . .

I am going to have to ask. . . .How much for them? That would be a big part of my decision to buy them. With 2200 watts, you should be ok with the 2 slug version if the box is designed correctly and your subsonic filter is set correctly. IIRC, the 2 slug vs 3 slug with long coil is 16mm vs. 27mm Xmax. Used BTL's are for sale quite often, so unless you are being offered for a smoking deal, look for the next deal with 3 slugs if you are worried about it. Brian

The worst part is people think the gain adjustment is a volume knob - If it is set at 1/2, then their 3000 watt amp can't make but 1500 watts. It is not a volume knob. A "perfect" amplifier is nothing more than a gain device. A voltage signal input is multiplied and reproduced at a higher voltage. With not all input signal levels being the same, the gain adjustment was created. Lets say your amp can produce a clean 40 volts on the output. If your amp's gain can be adjusted from 1 volt to 8 volts, that simply means: If the gain is set at 1 volt, when one volt is applied, you get 40 volts on the output If it is set at 4 volts, when you apply 4 volts, you get 40 volts on the output If it is set at 8 volts, when you apply 8 volts, you get 40 volts on the output You can see where this would cause problems with people thinking it is a volume control. The user sets the gain "half way" thinking he will get half ouput. If "half way" is say the 2 volt setting and the user has 4 volt preouts, then the result is the amp is clipping LONG before the radio is at full volume. As Nick mentioned, low impedance/high current throws another mix into everything. Not for the sub, but for the amp and the point at which the amp clips. The sub does not care - It has dual 1 ohm coils that will get X amount of current when voltage is applied. For the amp, running lower impedances causes the need for changes to the gain setting that you will need experience and/or will have to measure to get correct. Example: 3000 watts at 1 ohm requires 55 volts 3000 watts at 0.5 ohms requires 39 volts Remember, your amp is a voltage gain device. If you set your gain based on the "normal" 55 volt output, you will be clipping the heck out of it running at 0.5 ohms. These subs will handle 4000+ watts without any problem (and for long periods of time). If you smell glue with it on a 3000 watt amp, you are overdriving something. . . Brian

When you clip the 3000 watt RMS amp, you get more than 3000 watts RMS. In theory, if you could clip to the point of a squarewave without damaging the amp, you could get 6000 watts RMS. When you smell coil getting hot, you are getting int he area of causing damage. . .

Yes. . .I am Brian

When you say "7 cu ft after displacemnet", I assume you mean just after woofer displacement, since you don't know the displacement of the port yet. . . The best thing would be for you to post up some dimensions and we can help you with a box design. Knowing the box dimensions is pretty much a requirement to determine the port size and length. Brian

There is a sticky in the AA section with ordering info. Since you are in Texas, you can order from me, and AA will drop ship. PM me what you are looking for and I will get you prices. And the reason you get info through Scott is he owns AA in case you did not know. . .

Welcome!!! My uncle lives in Corpus. Visit there a couple of times a year. . . Also planning for CC Heatwave to be my first competition with the van Brian

I woudl do (4) 18's. They will be impressive in a wall in the van. . .

No pics yet, but just thought I would start a thread Bought a 1992 Astro and will start a new build soon. Ripped everything out of the suburban yesterday (13 hours of fun). . .picking up my new silverado crew cab today The suburban has made 8 yrs so I am finally going to get something new. Right now, the plan is (6) Mayhem 15's and (6) 40.1's. I am lucky I managed to get two more 40.1's over the past couple of weeks. Going to squeeze all the mids and tweets I can get in the doors and where ever else I can find. Pictures will follow soon. . . Brian

Nice

Turn the crossover up higher. . .

1000 watts per Havoc will work just fine. . .

Online is direct. Fi is a internet direct company. A few days to build, a few days to ship: http://www.soundsolutionsaudio.com/forum/i...?showtopic=7158 They use UPS. If the sub arrives damaged, they will take care of it promptly. . . Brian

Sweet. I just moved and left my projector with the house. Looking to get the Epson Home Cinema 1080p UB. Man what a projector for under $3000. Brian

Happy Birthday Nick!

Sell it and buy two new ones. I gain 0.9 dB from old to new with no other changes. . . Brian

Install looks awesome, but just a thought. . .I mounted Hifonics amps to a box like that in an install a couple of years ago. Did not take long for parts to start rattling around inside them. . .result was not good Might consider isolating them from the box with spacers and a dense foam mat. Brian
