x2. If you could smell them, you were hitting them with more power than you think. . .Or maybe it actually died a mechanical death. Sealed box, do you get a lot of excursion? Have you determined what actually failed?

foot pedal bass drum should play just fine through the subs. . . Not what I would consider midbass. . .hmmmm. . . If your amp has a subwonic filter, be sure it is all the way up.

Yes, per sub. No sure about the program, as I am not a Mac user. . .maybe someone else will answer.

Is that 0.67 impedance, or DCR?

Or somethign like a Lanzar Opti2000D that does max power at 0.5 ohms

I would add the HiXmCoil option too. Make it easier to sell if you ever decide to, and great option if you add more power.

edit - below is just an explanation of the alt trying to charge the batteries in a situation where the system draws more than the alt can provide. As already stated, if you alt can keep up with the system, the battery is just used as a reserve or to aid in high current peaks. Bigger battery = more plate area. More batteries = more plate area. More plate area = need for more charging capacity. Think about it: 1 battery, 1 250 amp alt. alt can charge that battery with 250 amps. 10 batteries, 1 250 amp alt. alt can only charge each battery with 25 amps. I thnk I have finally just fixed my van charging (fingers crossed). 15 batteries and 1 alt is hard on the alt Brian

I am 99% sure Scott said the answer to that question is NO! edit - I should add when I tested the new BTL, I gained 0.7 dB vs the old BTL in a one-for-one swap using the same amps, same enclosure, and same vehicle.

Wow, missed that. . . looks like too much power to me, so be careful!!! Brian

Looks like 2.5 ft^3 tuned to 23 Hz would work good. How much power do you have?

What does it matter? Order whenever you are ready. . .if they are out for the holidays, they will process the order when they return.

Should work fine. A lot of people do not like Hifonics, but I have never had a problem with them if you do not abuse them. Brian

No. It is the same voltage level as the RCA inputs - It is jus a pass through made for daisy chaining amps. Not in place of the 4-channel. your main speakers would still connect to the 4-channel amp. The rear ouputs of the deck would just drive the LOC. speaker wire = high voltage RCA = preamp level voltage

As already stated: Are you using preamp level for inputs to the Alpine? If yes, daisy chain the line output on the alpine amp to the preamp input of the subwoofer amp. No LOC needed If you are using speaker level inputs to the Alpine amp, use the rear outputs on the headunit, not the amplifier, as the inputs to the LOC. PAC makes a nice 10:1 LOC. It is my favorite for installing amps with factory headunits. Brian

Lanzar Opti6000D can be found new for around $1000. Almost same internals as the Soundstream XXX10000. some claim better results with the Opti6000D

I have got to get back to work on this thing!! Stay too busy all the time, but finally caught back up.

Is that computer going to make it mounted right there??? Should be some good vibration testing

I think you mean the amp's SSF. . . Just like the box depending on the t/s parameters, so does the tuning. Anyone have the old Arsenal t/s parameters?

Just have to watch them to see what they are doing mechanically. Thermally, if you smell the glue on the coils getting hot, you have gone to far. . . Unless you really know what you are doing, they are not going to live long on 5k. . . Brian

If I had my choice, I would do the 12" ported. . .

No. . .Calculated just shy of 2200 lbs added for the sound system.

You can, and more than likely will have to. Still not easy. Example: 3 ft tuned to 23 Hz with a 15 x 3 slot port - port has to be 70" long. I guess you could do a pair of 40" long 4" aero ports and let them stick out of the box. . . Brian

You can get the Dayton plate amps from Parts express. The 500 or 1000 watt version would work great. As already stated, the main difference is the recommended enclosures for car take into account for car cabin gain. 2.7-3.0 ft tuned to 22-23 Hz looks good, but good luck with the port length!!! Might want to try sealed. . . Brian
