my mate has a vn sedan with a clarion 2005 pro audio 1000w max(so clarion reckons) sub powered by a clarion pro audio mono block 1200w max/477w RMS amp. and it is in the right size box facing into the cabin through the hole between the back seats.
Now, I hav a vn wagon and i have a MTX road thunder sub rated at 100-200w RMS powered by a MTX road thunder 2-channel amp bridged at 150w RMS. its in a box about the rite size and my setup ****s all over my mates. now i know that being a wagon(and MTX rules) it will sound better but i didn't think it would sound this much better.
the subs are both in sealed enclosures.
does anyone have any ideas on how to make it sound better. do you think sound deadening would help a bit?

its all got to do with the amount of air that can be moved, by having a wagon ur car is a massive sub box.

yeah i've learn t a bit about air volume and stuff like that when i done some work eperience wit a car audio specialist. hatches and wagons a always better than a sedan.
its just that there is a fair diff. |

Okay, first up, take those max power figures and throw them in the bin, they don't tell you (or anyone else) ANYTHING about the sub. The only power figure worth quoting is WRMS.
As for the sound quality, a lot of it can come down to the build quality of the sub box, and the quality of the cabling used. That said, assuming that the both of you have the same quality sub box and cables, you might want to think about sound deadening, however depending on the specs of the sub it could be in the wrong box.
The reason I say that is that some subs are designed to only work properly in a ported box, others are designed to work properly in a sealed box, others can work in either happily. Also, the ports should be run into the same air space as the speakers. So having the subs in the boot and the vents into the cabin is just going to sound crappy. I'm not saying it doesn't get done, but in terms of SQ, it rates up their with 6x9's and MP3's.
Something else that's worth looking at is the tuning of the amp/head-unit. Make sure that the cross-over frequency is set properly, find out what frequency the box was designed for, and make sure you've got the cross over set properly. It might just be that you're not feeding your sub properly.
The biggest tip I can give though, don't have it facing into the cabin from between the seats. Might look good, but it'll sound like poo. Sit it up above the diff, but turn it around so that it's firing into the boot, towards the very back of the car. Have the sub mounted inside the box (ie. with the magnet inside the box, not sticking up outside the box), dunno which way you've got it mounted, but to my ears, that's the best way to go. |

we both got our subs magnet in cause i agree, it sounds better. my box is a cheap pre-fab box and my mates we found the inside volume specs that clarion rec and made a box out of 20mm MDF no sound deadening inside box.
I usually work with RMS figures to but i couldn't find any for the Clarion.
i just remembered when i installed his setup, his headunit only had rear pre-outs so i hooked the amp up to them. where as my head unit has sub pre-out. could it do with quaqlity of head unit. i have a JVC KDG-615 and old mate has JVC KDG151 or some thing. |

The quality of the h/u will have a little bit of an impact on it, but shouldn't make THAT much of a difference. Typically the variation between good and bad headunits is in the internal amp, since you're running on the pre-outs, that doesn't need to be considered. For this I'm willing to say that your head units are about the same quality.
Spin the sub around so that it faces into the boot and consider building a properly configured box for it. Volume is one guide, but SHAPE can have an impact on it. Get your hands on a copy of WinISD or Bass Box 6 Pro. A bit of foam inside the box can help. Since you listen to metal, you'd be better off with one (or two) 10" subs than a 12". 10" subs are much better for fast punchy double bass kicks, 12" subs are a good compromise in that they can do some kicks, but will also give nice long 'burbles' for R&B, generally 12" subs are used for rock. 15" subs are useless for metal, but are wonderful for long rumbling bass notes.
I will say this though, I've got the JVC KD-G615, coupled with the 12 disk MP3 changer and I can't fault it. It's bloody awesome. |

What's the difference between understeer and oversteer?
Understeer is when the driver is scared.
Oversteer is when the passenger is scared. |
