well, we had a 3x dbdrag here in cincinnati and I decided to show up and hang out for a bit. I got to run the 4 8s..... 131.7 dB while slamming the voice coil into the backplate.. and that's ony with 325-350 to each 8. not the full 450 it also doesn't sound quite as good as I had hoped either, I think having dual 2 ohm subs wired down to 1 is changing the T/S perams.... and I don't think the T/S numbers eDuh has on their site is right.... so I'm thinking about ditching the 9Kv.2s. they are punchy and get low but I think I can do better. so I'm going to try sundownaudios E8 next. they come in at 4.25 deep and are built simalarly to the 9kv2 or arc 8. but with a stiff suspension and smaller box requirement... I've also heard people burping them with 800 watts. I'd like to try all my options with the current box.. I know the re8s are out.. those bottomed out with only one of my amps, so those are out of the question.. if these don't work I know the IDQ8 and arc 8 will fit... maybe the cvr8.. and if that dosnt work I can try the tang band 8's too... if I STILL can't break 140 sealed I can try 4 8's ported with a seat lift but then I would lose all my low end I'd propably have to ditch the 4 8s at this point since a seat lift would allow me to run 2 deep high xmax 12's

 

I can get 8L5's, 8L7's or CVR8's. If you want... Just let me know...

 

As cool as the whole four 8s idea is, that is why I would never do it as a daily install...just wouldnt give me what Im looking for I dont think without sacrificing all your SQ.

Have you looked at the RLi 8s?? That would be my first choice if I ever decided to look at 8s.

 

the rli-8's were my first choice but they wont fit under the rear seat without a seat lift.

 

I sell you my 10W6...

 

+1 for the 8L7's. I had 4 of them doing mid 47's @ 45hz (new TL) in a daily box tuned to 33hz. Not the greatest number ever, but they got pretty damn loud and sounded good doing it (IMO).

 

they also wont fit under the rear seat

 

Not bad for four 8s in a daily install
