Twin Sub In Box

[Bonjaz]

Power = Current x Voltage

less current or voltage and your going to get less power output and depends how its all wired...but as the others have said I am gonna guess your amp isnt big enough to make the "HECTIC DOOF" your after haha

Facing subs toward the front will most likely reduce the amount of bass but experiment. Sealed enclosures are really about SQ and are not the best design for bass volume. A ported box will product a lot more bass and 10 inch drivers do not play as low as a 12 or 15.

How low a driver plays is down to Fs (resonance frequency) and not driver diameter. Adire Audio Tumult 12, has a lower Fs than almost every car audio sub on the market.

Ported enclosures are more efficient above the port frequency, but less so below it. If you have a ported enclosure it will generally produce more bass below 50hz - port frequency than a sealed setup, at the expense of group delay (kind of like speed). Sealed designs are generally easier to get right, more forgiving to construction and design tolerances, at the expense of roll off. Sealed designs tend to follow the natural increase in bass that you get from a car, resulting in cleaner, more linear sub bass and better integration with the front speakers.

I've only got a cheap system in mine atm, 140RMS 2 channel bridged running a 1300w 12inch in a ported box and bass is more then enough. In the car that is, not that loud out of the car.

It's easy to get loud bass but as someone said before if you want a quality sound you gotta pay for it.

Oh and mine sits right in the middle facing the front, worked best in my car.

wow!! thanks for the replys everyone. ok so I'd better clarify a few things.

amp that powers subs = ECLIPSE DA6213 (500WX2)

amp that powers speakers= ECLIPSE 36401 (50X4)

headunit = JVC KD-R905

its set up with 2 sets of rca's. 1st set runs to sub amp

2nd set runs to speaker amp

like I said before power cable is run to sub amp first and looped to second amp. the DA6213 apparently draws alot of power

so maybe looping the power from it to the speaker amp is draining all of its power????

thanks again u guys rock!!

disconnect 1 sub and see how it sounds.

The negative positive wires for the sub might be the wrong way around make sure the negative positive wires are the rite way around.

I checked all connections they seem ok..... I might run another power cable to the sub amp and see what happens... because in theory my amp is strong enough?????

What subs? Ohm ratings? That amp will be only 250wx2 at 4ohms. 500wx2 at 2 ohms. 1100wx1 bridged at 4ohms.

Packs plenty of punch, depending on your sub specs, you might be better running one sub on the bridged setting. I am assuming you are running 4 ohm subs, which would only give you 250w in this case.

So what model are the subs?

hey mate, the subs are clarion sw1251 subs, 4ohm by the looks of it..... continuous power 250watt peak 700watt...

should go hard in theory???

my 12inch sub box doesn't fit under the parcel shelf :( let alone both....
