You should consider the enclosure size you will be needing, some subs work best in big enclosures, audioque subs usually work best in above average enclosure sizes, 6 12" subs would require a really big enclosure..

If you can provide the dimensions of the biggest box you can fit then something can be worked out.

Audioque HDC3 subs are known not to go low but be very loud, the SDC2.5s are different, can go lower and stay efficient tuned to 32 to 35Hz, no audioque products are SQ as such but can sound nice for most users. probably will take near 1KW each.

The 2.5s work well with 4 cuft net each so 16 cuft net for 4.

So some random dims for an enclosure that would meet the 16cuft@34Hz would be:

External Height = 38 in
External Width = 37,69 in
External Depth = 26 in

Thats 21,55 cubic feet, I'd think about wasting so much wood on 600W subwoofers. Don't know if you get my point.

i understand but im not really going for a daily driver setup more for car show appeal thats why i want 3/4 subs at the same time i wanna watch prices not looking to get extremely loud neither thats why im going for a 2000-3000 rms range spending no more then $200 per sub

im looking at the re audio sex subs also fi ssd subs price wise but man does these subs need alot of space also i can not find the cargo specs but these trunks are really big(wide)

The volume I just gave you above is for 15"s, my apologies, for 12s 2.50-2.75 net cubic feet per sub is about the maximum you would need. SSDs will probably do ok on 2.3 cubic feet per sub.

I am thinking that at least 3 12" subs will fit front firing but the best way to know is to measure yourself witdh, height and depth, dual 15"s could be an alternative and can get really loud and low.

Don't do the typical hood set up and cram a bunch of subs into the trunk in an enclosure that's too small.

2 of the 12's in 4.5cubes tuned to 35Hz off 1200-1500watts will hit very nicely. Ran that exact set up for around 6 months.

If it's a show car, then make the box look nice. Wrap it in vinyl/leather, custom paint for the port, ect...

@ Joe, HDC's can do just fine on the lows, I do 56+ @ 30Hz

Ok, here are the:

1) SDC2.5 15" 4cuft33Hz
2) HDC3" 15" 4cuft33Hz

Normalized gains for each:

1.

2.
Upload

When tuning for a sub is too low for it. the gain will dip just above the tuning frequency and then recover afrterwards.

if you're able to build it inside the trunk then yes you could do more then 2 subs.

HDC3 takes the same size enclosure, but will handle 2-3x the power...

The HDC3's suspension out of the box is very stiff. After a few months of use daily they will loosen up alot and get nice and low. It takes a while for them to loosen up tho. At least thats how the copper coil versions I have used were, but I've heard the aluminum coil versions use different suspension?

Actually the new v4 suspension has a lower fs and will play lower then the old HDC's. I've reconed a few to v4's and that has been my observation by ear and on the TL...
