Hey guys I need a 10" sub and also need a nice amp to power it, I have no idea what would be best for my application because i don't know anything about car audio.......It will be installed in a stealth box that Houman's buddy built Let me know what you got, Thanks.

 

I am assuming your box is sealed? is this correct?

Look for a sub that has a VAS (recommended sealed enclosure size) of around 10-14 liters or around 0.3-0.5 cubic feet.


Next, decide whether you want to maximize bass extension down low, or if you will be happy with max SPL at higher frequencies. If you want extension look for a sub with high Xmax (excursion, the more the better for bass extension) and lower Fs (resonant frequency). These qualities can sometimes be difficult to find in a 10" sub, especially on a budget. A higher excursion sub will usually be less sensitive, and will thus require more amplifier power.

If you want to run a smaller, cheaper amp then you should go with a more efficient sub. The only problem with this would be that you sacrifice bass extension since your cabinet is so small and cannot be tuned easily unless you go ported. You can add filler to the box but this probably won't change the Q very much.

here is what I would look for, in priority order, to get reasonable bass extension:

1. VAS of 10-15 liters
2. Fs of 35 Hz or lower
3. 12+ mm of one way Xmax
4. sensitivity of around 85 DB @ 1 W/M, but the higher the better
5. minimum of 200 watts power handling
6. single 4 ohm voice coil

To power this I would try to find an amp that puts out at least 200 watts into a single 4 ohm channel.

Naturally if cost is an issue you will need to sacrifice some of the items in that list. If you want we can try using software to model different subs (assuming we can find their T/S parameters) to see how they respond to that enclosure at different power levels.

 

I have a kicker comp 10" 250W RMS sub for sale .. 90CAD.. i paid 149.95CAD + tax at visions for it, only used it for like 4 weeks...

drop me a line if interested.........

 

I also have a 10 " dvc for sale if you want a big one, 2 actually but I may just keep one for use later on .Its a Rockford Fosgate 10 " dual 4 ohm voice coil , 400 wrms 800 watts peek , big phatty rubber sorounds etc , hugemungous magnet retailed close to 400 $$ I need 180 .00 $$ . It may be a bit more than your after if you just want some bass .

recomended box volume .63 cubic feet , sounds great in stealth box
