yep. audiobahn used to make some 6's. look on Realmofexcursion.com there is a video of some guys with 2 of them in a massive TL enclosure or something. everyone that heard it though it was at least 2 10's.

well, I got industrious and did make some sketches and calculations. It can be found here: [ http://dce.ath.cx/images/enclosure.jpg ].

The image is almost 400 kb, sorry 56k-ers.

The speaker is rated for 2.5 - 5 ft^3, so this seems like it will work pretty well.

Tonight I'm looking for some tips on wiring kits... on ebay I'm seeing deals for 4 gauge wire at about $35 shipped. Do you think I need 4 gauge, and does it matter what brand? How many feet of main wire do people actually use? Some come with 60 amp fuses too, which is like 720 to 800 watts depending on voltage, which is probably enough for this application. Have any of you used circuit breakers with your setup so you don't have to replace a fuse if it blows? I'll bet they aren't much more expensive than a couple of fuses and work related to replacing them.

I hope I'm doing right by asking all these questions in one topic; I figure it saves space on the message board.

60a fuse?
60*13.5=810
that is the power supplies maximum wattage. actual power to the speaker is usually around 60-70% of that. so 480-570w...

so you think I'll need more than that? I can probably get a 75 amp circuit breaker to replace the fuse so I can get the full 1000 watts that amp can draw.

CBFryman · #21 01-31-2005, 09:39 PM

get what the amp needs

If I end up getting a capacitor, that's gonna go after the fuse/circuit breaker, right? How does the current work with that? I've learned some basic electrical stuff, and capacitors can have a fairly large current draw when they're first charging up.

No cap, invest that money in a 2nd auxilary battery. but if you where to install it yes it would be fused before it. you ALWAYS fuse the power wire with in 18" of the battery. this will protect any shorts after that. period. the only itme you refuse is if you usea distribution block and you send say 0awg to the block and 4awg to the wires from post distribution block. unless the power wire to the distribution block is fused low enough to where 4awg can handle the current with out burning. even still it is a good idea to fuse anyway so that instead of all of your amps going out only the one that shorted.

I still can't get over having a sub needing 3-5cu/ft for a box!!!! No wonder I see so many rears of cars dragging. And here I thought they were just hauling fat girls!!!

CBFryman · #25 02-01-2005, 07:12 PM

Dude, you really have never heard a good system have you? 5cuft large? there are thoes who beleive anything under 200l is small...big sound from small enclosures is done with either horible SQ or tons of power.

what he said^^^^ big boxes sealed or porte require less power to get LOUD..... these are usually subs with softer suspensions that are naturally easier to move too.

Diceman83 · #27 02-01-2005, 09:55 PM

Does it matter how old the aux battery is? I have an older battery from my Dad's 93 ford ranger that we mistakingly thought was dead, but it turned out the starter had died. We decided to keep the new one because walmart throws so much crap out after people return it. Do you think it will work alright?

Did anyone look at my designs? I'd like to hear some feed back before I try to build this monster.

Thanks guys!

I have an 8" sub glassed into each door ... most people think there is a 12" sub in the back

Well yes and no. Most other sub makers can have a sub tuned to the same frequency as these you talk about but in a box 1/2 the size. I know it doesn't really matter to you guys. It didn't back when I first started either. Today it does. I don't want a 10cu/ft box when I could have a 3cu/ft box sound as good or better. These subs you guys like requires large boxes because the motor structure is weaker and that is also how they are tuned. They are just a copy off of their home stereo line.
