Subwoofer Help

[maximus73]

<font color='#000000'>I recently moved into a new home where the builders pre-wired the house for sound. &nbsp;In my home theatre room there is a run that is labeled &quot;subwoofer&quot;. &nbsp;This cable is a thick yellow cable with two pairs of speaker wires inside(red&amp;black, white&amp;green). &nbsp;The one end of the cable(receiver end) has a device on it that takes the two pair and turns them into a single rca input. &nbsp;The other end has nothing but the 2 pair of speaker wires sticking out. &nbsp;My questions are: &nbsp;What is that converter on the receiver end called and what should I look for when going to buy a subwoofer? &nbsp;Thanks</font>

<font color='#000000'>Strange.. usually, you'd just run a single cable and then split the end at the subwoofer with a Y-cable to feed into both inputs of your subwoofer... Your scheme seems to indicate that they ran two cable runs and joined the end at your receiver.

If the other end isn't terminated with RCAs, you'll need to do that, provided you are using line-level inputs to your subwoofer.

<font color='#0000FF'>hawke,

Do we still need to use the Y cable for subs as most of them are set to bridge the signal when a mono RCA cable is attached to the L channel? I know Yamaha and M&amp;K doesnt reccomend using Y cable for RCA in.</font>

 

[Audioholics]

<font color='#008080'>Depends on the sub. Velodyne CHT Series need the Y-adapter. I don't know what model sub maximus73 has.</font>

<font color='#000000'>so is it possible guys? if so can u tell me how?</font>

 

[Guest]

<font color='#000000'>does anyone even know if its possible?</font>

 

[Audioholics]

<font color='#008080'>You can connect either a speaker level input to a car sub that accepts AMPLIFIED audio signal (but it will require the sub to have an integrated crossover), OR you can connect the LINE LEVEL output of the receiver to a self-powered car &nbsp;subwoofer.

I'm not familiar with the model you have - but there are the guidelines to follow. Connectors aren't a important as the presence of a crossover, or the sub being self-powered.</font>

<font color='#000000'>uhh ok, can i get that in english??? jk &nbsp;i am a noob though so could u explain a bit more?

[Audioholics]

Hang loose and save up for a powered subwoofer.</font>

<font color='#000000'>If your subs have built in crossovers as I suspect most of them do, then all you have to do is connect your receiver's amp section to the sub and then take the connection from the sub to your main speakers.

Eventualy, a powered sub would be the best choice for you as it would tax your receiver less and enable you to get better performance out of it.</font>

<font color='#000000'>k thx guys ill get a powered sub... sounds like it be the best option i appreciate the help</font>

 

[Guest]

<font color='#000000'>do u guys have any recamendations for a mid-grade powered sub?</font>

 

[Audioholics]

<font color='#008080'>What do you mean by mid-grade? How much do you want to spend?</font>

 

[Guest]

<font color='#000000'>under $300 US</font>

 

[Audioholics]

<font color='#008080'>Try looking at Velodyne subs on eBay
Axiom Audio's EP series starts at $380, but if you wait for a B-stock deal, you may find it cheaper.</font>
