two tens in the right inclosure! the type of tens will no doubt make a big difference. by the way what kind of vehicle is this in. and were your previous subs in a different vehicle that u figure sounded better!? this is not to be critical, the info is necesary.

 

if you want less deep bass ie muddie bass make the box smaller
that increases the midbass and produces less deep bass
and the terminalogy for that is boomy bass

 

More does not neccessaraly mean better tho.

 

The vehicle is a 2004 Kia Rio. I think the two tens sound great, especially after tweaking them a bit more (and more, and more...) since my original post a few ago. I increased the gain a bit and adjusted the parametric eq onthe JL 500/1 (very nice feature to have onboard an amp)to reduce the low-end roll off. Now I have these subs sounding just right, the perfect balance between SPL and SQL. I can feel the drum-kicks in my chest and the low-end is plenty loud! If I had the cash, I would upgrade to higher quality subs cause I know I can do better with my amp, but the money tree just isn't in bloom right now.

As for the previous sub-car combo, I had two 12" Memphis M-Class subs in my Nissan Pulsar hatchback, but I they were undepowered with 2 channels off an AB class amplifier and were only nice at lower volumes (amp could not control them properley when I wanted them loud - very frustrating!). I know the Memphis 12s sound better than the Kenwoods because I had a chance to compare 1 of each in my wife's Ford Ranger. I have one Memphis in the cab of the truck and a JL 250/1 running it and the SQL and SPL is definately better than the Kenwood 10. (yes, I had one 10-inch in her truck, took it out and bought a matching one for my Kia and put one of the 12-inch Memphis' in her truck and sold the other one).

I think it would fun to try 4 eights just for the hell of it as I am always looking for reasons to play in my trunk. I AM A CAR AUDIO JUNKIE!!! [img]graemlins/headbang.gif[/img]

sounds like u answered your own question. lol

 

The problem therein lies the fact that 4 8's cannot possible achieve the bottom of the spectrum in the frequency range. An 8 should play down to possibly 80hz, a 10 down to 50hz, and a 12 down to 30hz. These are recomendations for average wattage, with subsonic filters and a ported box that is tuned 5-7hz below sub resonant frequency. If you are looking for tight bass in a small enclosure, go for sealed, but if you want the low end extension then go ported.

Four 8s...from 44hz down to 20hz.

Never had a lack of bottom end.

Or course I had a wee bit of power on them. [img]smile.gif[/img]

I would have to whole-heartedly disagree with that statement. Multiple 8s can without question play down low with authority.
