The damage to the actual speaker is just on the surface...just a scuff. Looks worse in the picture. The woofer was in the back of a Subaru Crosstrek which has a very small cargo area. So it is 99% likely that the damage is from having things against the woofer while it was playing. I don't think it was a one time event that cause it but it might have been...something fell on it or something. The woofer has actually been unhooked since Christmas and I don't know how long the damage has been there. I haven't been driving the car much since November. My wife has. I've been driving the truck. Anyways, I pulled the system out of the Crosstrek yesterday because we traded it in on an Outback and that's when I noticed it. I guess I'll try the RTV and see how that works. The hole isn't all the way through so it seems it just needs patched to keep it from getting worse. I guess I'll see what happens....worse case I'll have to get a new subwoofer in which case I'll go bigger. This one is just an 8" Sundown Audio E8. Thanks for the help.

I pulled the box out of my hatch today to find that there's a hole in the surround. Not sure if it was ripped out or rubbed though from having stuff against the sub while playing. I was wondering if it could be repaired by me or would I have to send it in for repair, in which case it wouldn't be worth it since shipped and repair cost would be more than the $100 shipped I paid for the sub. Good excuse to move up to a 10" I guess...if I can't make the repair myself.

Ok...I have the subs and I want to start the box this week. I am not set on the aeroport yet so I was wondering if someone can someone help with dimensions for a slot port tuned to 40hz? Subs will be seeing about 700w RMS. Or at least tell me if this looks right for the slot port....height: 13.5" width: 1" length: 21" tuning: 39.90Hz Granted I am only using 8" subs but from all the pics of all the boxes I have been looking at....a 1" wide slot port just seems tiny. Any help would be greatly appreciated.

Oh wow...I cannot even imagine what you are going through. Being a father myself there is nothing in the world I would think could be worse than getting that news. I am so sorry for your loss but at least it does sound like Sean is at peace now.

Will do...thanks.

I am getting ready to place an order from Knu for my wiring. I just want to make sure I get what I need the first time and it's the right stuff. First of all...do I need one or two runs of 1/0g power wire for my two amps? The mono block will likely be an AQ1200d at 2 ohm (870w RMS) and the other amp for my mids/highs will be no more then 150w x 2 @ 4ohms. So if a single run is sufficient, once I get the wire to the amps and I go to split...what size wire should go to the AQ amp? I am just wondering because I didn't see a dist. block on Knu's site that allows for a 1/0g wire to be split into 2 or more 1/0g wires for multiple amps to be ran with that size wire. I figure 4g would do for the smaller amp...I just want to make sure the sub amp is properly feed. One other question for now...terminal ends...is #1 the correct size or do I need larger? Thanks and sorry for the newb questions.

Like it says...any thoughts on which is better? I can get either set for the same price for the 6.5" component set. This will be for my Jeep Cherokee system and whatever I get will see 100-150w RMS depending on the amp I get. I listen to pretty much everything but rap and country. I'll have two Sundown Audio SA-8's handling bass duty.

Also...how do I figure out the dimensions of a slotted port for a box for two SA-8's @ .6cf each? I figure tuned at or around 35Hz.

I listen to a lot of different stuff...generally rock, classic rock, techno/electronica, industrial metal, no rap or country though.

Also, what is the best tuning for daily driving (music)? I am about to commit to a pair of these and start building the box.

Can anyone help with port size and placement in the box. I used a port calculator and for 32Hz tuning it says I need a 3" port 11" long. Just want to make sure that seems right. Also, if I did want to do a slot port, how do I go about figuring the dimensions for that? Sorry...I've built lots of sealed boxes...never a ported box.

Thanks. That's where I am at now...trying to design the box. Not having much luck. I know it shouldn't be hard but I just want to make sure I do it right. The plan is to have the subs firing up and the port to the rear. Box according to Sundown should be .6cf per sub plus .10 for displacement so I was planing on a single box of 1.4cf. Just not sure about the port. The box will just be a simple rectangle box and the port I planned on using an Aeroport to keep it easy.

No kidding...I like it. Thanks for the intro to a new genre to me.

It's a 2002 Grand Cherokee so it would be pretty similar to a 2007. So in a 1.5cf box a 4" port 16" long would tune the box to around 35Hz.

I generally listen at a comfortable listening volume but of course there are those occasions when you need to show off a little. I don't listen to a lot of really bass heavy stuff but I do like my industrial metal from time to time.

Do you think that running 1500w RMS will be ok with stock electrical? I will also in time be adding a second amp for front stage that I anticipate will be in the 100-200w RMS range. Someone asked before about adding more subs and no...I won't be adding more then the two. I just want to make sure I don't get too much amp but of course I don't want too little either.

I also wanted to add that I am trying to do a system that won't require me to upgrade my electrical other than the Big 3. I have a 136 amp alternator on my Jeep stock so hopefully that will provide enough juice to keep things running.

Ok...so with the 15001D, would I run it at 4 ohms 600w RMS, 2 ohm 950w RMS, or 1 ohm 1500w RMS? And the box should only be the max size listed which is 0.6cf each? So a box for two would have 1.4cf to allow for displacement? And this would be an ok setup for a daily driver with no comp. aspirations? I am sorry for such newb questions...I have been out of the game so long that it really is still mind boggling that so many subs and amps are running on this much power. 12-15 years ago it seems that only the most expensive amps could push that kinda power. I'm still getting used to it...lol Thanks though for all the help so far...I do appreciate it.

I personally can't afford a Sundown amp at this time. That is why I was thinking Audiopipe. I want more SQ then SPL but I am not looking for hardcore SQ.

I have decided to go with a similar, well, the same setup really. I want to do two SA-8's in a ported box with a aeroport to keep it simple. My question is, using an Audiopipe AP1000D at 2 ohms will put out around 700w RMS. Tuned to 30Hz, what size box should I be looking at? One other question...is there an better amp option for around the same money? I can get the Audiopipe for around $160 shipped. Budget is a big concern. Thanks for all the help and sorry about hijacking.

Thanks again. I figure for now a aeroport will probably be easiest. Maybe after I get this first box together I can mess around with some different types of ports. One question about the aeroport...does it matter if I use a shorter 2" port or a longer 3" port as long as the length is correct for the tuning?

Ok...thanks for the port info. I was typing as you were posting my last post. As far as math and physics knowledge...yeah...pretty lacking in both.

Ok...thanks. How about ports, location, size? Also to keep the box as slim as I can...what is the minimum distance I should have between the edge of the basket and the edge of the box? The O.D. of the sub is listed as 8.25, so would I be able to make the top depth of the box somewhere between 8.5" and 9"?

Right...the safety of the subs was one concern I did have. I don't know anything about unloading so that was never a consideration. I'll look that up so I know what it is. And just an FYI...using a base depth of 15" there would be a gap of 26" between the sub and the hatch...just in case anyone wanted to know.

haha...thanks...I was worried...I hate starting threads asking people to do things for me but I have been reading for hours over the past couple days and just can't come up with the answers to what I need to know. Plus there is so much conflicting info out there it makes it even more difficult. Like the airspace needs of these subs. I read one place not to exceed .60cf ported but then I read people throwing these things in boxes with 1.5cf of space.
