Hi, I just bought an insignia reciever from best buy. I've got all the speakers setup and it all sounds great. Quite a step up from my old stereo with 2 channel output, now i got 5.1 , but anyways, I was wondering how or even if i could connect this sub i have. It's actually meant for a car, but I thought maybe there would be a way I could use it for my room because I don't have an amp for my car, so the sub is just sittin' there. The sub has the red and black connection slot.
Does the car sub have any crossover network included? Or, is it meant to be driven from an external crossover? If so, what does the receiver have in the way of LFE crossover settings? You will require an external amplifier, I would guess, from the brief description you've provided. And, as a rule, car subs do not work well in the larger environment of a home. If you have no crossover, no amp and a sub poorly suited to your needs, I would suggest you save enough to buy a proper sub for your HT use.
As Jan stated, you will need an amplifier, a properly designed enclosure, and some way to adjust were the sub kicks in and the other speakers don't try to reproduce the low frequency signal.
Actually, some decent results have been obtained with some so-called 'car' subs.
It all boils down to the diver's Theil small parameters, ( http://www.thespeakerstore.com/glossary/understandingspecs.htm ) and designing and building an enclosure to match ( i.e. Box volume, sealed or portedbox, port length and diameter, etc.)
If you are interested in building a sub or buying a pre-made enclosure like ones available from Parts Express, the guys here are a V good resource for info: http://www.htguide.com/forum/forumdisplay.php4?f=6
thanks, i'm pretty new to the whole ht setting so, i wasn't sure if it would work or not. I just had it, and I probably won't be getting an amp for my car soon, so I just thought maybe it could be put to use. but thanks anyway, i'll just wait and get a more suited sub.
