Hooking a car sub, up to my Z-5300's

[-=Pyro-Psycho=-]

Hmm would anyone know how to do this? I'm guess that there is probably a way to do this, but I'm not really sure how. I don't have the sub here yet, so I haven't had anytime to look at it. I'm hoping some of you will know how to do this, and what I will need.

for one you will need an amp to power said sub.

I guess the amp for the 5300's can't handle another sub huh?

uhm i think that would probably be pointless. The build in amp in the The logitech z-5300's, probably doesnt put out alot of wattage, just adding another sub wouldnt make the bass louder,it would just divide the amps bass wattage by 2, and split it into two subs. It might be cool to have surround bass though

Not true, people have hooked up multiple subs before (they were Z-5300 subs, or 680 subs) and increased bass. I was wondering if it would do the same, and be possible with just a sub for a car.

I would think he's trying to replace the 5300's sub, no? I dunno, but how powerful is the sub for that system? I'm guessing it's not like the 5500/680 unit(s), eh? Anyway, good luck, heh I haven't messed too much with car audio yet (no car) so I dunno what you would need to do to set that up...

No I don't wanna replace, I want to add it on. I got a 12" sub for free and I don't have a vehicle to put it in, so I figured why not just add it on to my PC? :)

Hm......I wouldn't do it. Here's the reasons......

In order to hook up another sub, you'd have to daisy-chain it to the existing sub, which would mean cracking open the case. Since the Logitech sub boxes are sealed, no screws visible, you'd have to cut open the side........which would pretty much destroy any bass you had going on there. Second is the ohm rating. I'm pretty sure Logitech used a sub with a close wattage and ohm rating to the built-in amp. If the sub inside is, say, 4 ohms, and the amp's max rating is 4 ohms, adding a second car sub (usually 4 ohms, but can be as low as 2 ohms for a dual-coil sub bridged for mono use) will lower the ohm rating too far. Say, you get a dual-coil sub, rated 4 ohms per coil, bridge it, then run it in parallel (hook the connectors together positve/positive, etc), you'll drop the ohm rating for both subs down to just below 3 ohms. After a relatively short time, you'll burn out your amp.

I really wouldn't try it.

Also of note, car subs have a different frequency "map", to compensate for the small confines of a car. They don't sound nearly as good in a large room.

The guys who hooked up multiple '680 subs used 1/8 splitters at the PC, and ran cables to each sub, which is perfectly fine. In that case, each speaker is getting it's own signal load, on its own amp.

Ok.. Basicaly it works like this...

The sub needs power to work. The amount of power is dtermined by the rating of the sub. (i.e. 200 watts....) Now the amp in the sub with the 530's is, like most have said, probaly set just right for the sub its powering. So you would need to find yourself an amp that would fit two essential properties of the sub you have. 1. Wattage. (If max watts on the sub is 200, you'll be fine with 100-150 watt amp. The RMS of the sub will most likely be in that range.) 2. ohms..Make sure the sub is designed to be run at whatever ohmage you are looking at. I would recommend 2 ohm mono. (When looking at amp wattage. make sure you read what it is for 4ohm and 2ohm, and also mono and stereo on both of the ohmages as well.)

Once you have the proper equipment, there are a couple of angles of attack here. I think the easiest being, hooking the amp directly to your computer. and that way you'll have the controls for the logitecs and a seperate control for the second sub. If you aren't looking for two controls, then things may become more complicated and at that point not worth it.
