im new with subs, im thinking about getting two infinity kappa perfect 10.1 for my civic...what i was wondering is how would it sound if i put the subs in two different enclosures?? and facing each other on different sides of the trunk like in the picture of what someone had...will anything happen to the sound by doing these??

 

Experiment, but generaly speaking you subs will sound louder if you fire them tward the rear

 

You may get some cancellation if subs are pointed towards each other, the most convenient would be a single box, made to fit up against the back seat, [same angle as seat] subs facing rear, and mount box with piano hinge, [along front of box, next to seat] that way if you need to you can fold the seat forwards and flip the box forward, and have the whole hatch, and make it easy to get at your spare, and if you make the box narrow enough, you can mount it off to one side and leave a gap so you can fold the seat down on that side and still be able to carry some longer items. 94

 

soo puttin the subs in different boxes doesnt effect the loudness or bass than putting both in one box if both ways are facing the rear??

 

as long as there phazed right and tuned right it will be fine.

Because both the subs, [speakers] reproduce the same frequencies, [low-pass] at the same time, you want the speakers to work as one, [couple] so placing them as close together as you can is the best way, it makes no diff. if they are in 2 diff. boxes, as long as they face the same way, are in phase, and are as close to each other as possible, and of coarse are in the proper sized and shape box, [a cube is not a good sub box] 94

 

what amp is good enough to power both infinity kappa perfect 10.1?? can a 1 channel amp power two subs?? i think i heard it somewhere but wasnt sure cause i thought there would only be one negative and one postive...

 

Yes a mono block sub amp would be the best to use, you just have to match the subs too the amp. or the amp too the subs, your subs are 350W continues 1400W peak 4 ohms so I would find an 700-800W rms into 2 ohms mono block sub amp, wire the subs in parallel for a 2 ohm load, done deal. 94

 

so buy wiring them in parallel is wiring the two negatives and positives of both subs together to the one set of negative and positive in a one channel mono amp?? right?? just makin sure what wiring in parallel meant...oh and what would the rms be if it becomes a 2ohm load when i power both subs?? and would this be a good amp?? http://www.cardomain.com/item/INFREF1210AZ

Yes, parallel wiring is speaker pos. (+) to other speaker pos. (+) to amps sp. pos. (+) term and the same with the neg. (-)

The power handling of the subs stays the same, it's the output of the amp that doubles every time you halve the imp., [load] just like the amp you link to it will make 854W rms into a 4 ohm load and 1300W rms into a 2 ohm load, it does not mater is the load is one or two or more speakers, the amp "sees" the load, not how many speakers, although 1300W rms into 2 - 350W speakers is a little overboard, you need an amp that makes 700W and IMO no more then 800W into a 2 ohm load. 94

 

what about this kind of amp?? http://www.cardomain.com/item/INFREF611A, it has 657w rms at 2ohm...will that be ok or will that underpower it?? i was tryin to go all infinity thats why and thas the 2nd wit the most watts at 2ohm...ALSO, what does putting the box up against the backseat do?? will that make it bang more or what?? cause i got an amp mounted on one side of the rear seat and was planning to put the other amp to power my subs on the other side of the rear seat

 

You should be ok with that amp, placing the box up against the seat is just to get it out of the way, [the subs face the rear] as much as possible. 94

 

can all subs run at 2ohm?? because i was planning to get the regular kappa perfect 10.1 (non D, DVQ etc.) but i noticed the others have different impedance...like the regular 10.1 says 4 ohm and the DVQ says 2 or 8 ohm...does that mean i cant power the regular 10.1 at 2ohm?? and what are the other differences between all the other infinity kappa perfect 10.1 (D, DVQ, VQ)?? and which should i get to power both subs at a 2ohm load??...

The + and - terminals are put on there so you get the proper phase. Having only one + and - is fine. Placing your speakers facing each other is also ok. You will know if you have something hooked up wrong by a drastic reduction in bass. If this occurs just invert one of the speaker terminals and your good to go.

Speakers have different impedence to match different amplifiers and the needs of the user. The DVQ speaker you speak of has 2 4 ohm voice coils. so you can run it in parallel and get 2 ohms or series and get 8 ohms. You could run just one voice coil and get 4 ohms but you would reduce the power handling in half.

The question could be, can all amps run at 2 ohms, and the answer is yes and no.
The question should be, are all amps stable at 2 ohms and the answer will depend on a few things, EG: an amp that is stable at 2 ohm in it's 2 ch mode may not be stable when bridged into mono, [as is the case with most 2 ch amps or most multi ch amps] however most mono block amps are stable down to 2 ohms or less.

You can pick your subs, and then pick an amp that will run them, or you can pick an amp and then pick subs that will work with the amp, or the best way is to pick both together.

You want to get the "regular kappa perfect 10.1" if you mean one sub, it is a 4 ohm sub, so no, you "can't power the regular 10.1 at 2 ohms" it's a 4 ohm speaker, the amp will see a 4 ohm load.

However if you have two 10.1 4 ohm subs, [or one DVC 4 ohm sub] if you wire the two 10.1s in parallel, the amp will see a 2 ohm load, or if you wire the two VCs of a DVC 4 ohms sub in parallel the amp will see a 2 ohm load.

It's how you wire, [parallel or series] the subs or VCs together that determine the final impedance, [ohms] the amp will see. 94

 

^^^soo as long as i wire two regular kappa perfect 10.1 in parallel, the amp will see it as a 2 ohm load...and this isnt bad for the regular 10.1 being a 4ohm speaker??
