Sub-woofer connection question


Hi all,

I have a Music-Hall a15.3 integrated amp and a JL Audio 8" "Dominion" powered sub-woofer.

The sub-woofer has speaker-level inputs (R & L, + & -) but also has line-level RCA inputs.

The amp has an RCA out as well as (of course) speaker-level out.

So I can connect the RCA out of the amp into the RCA in of the sub-woofer, but I can also piggy-back off the amp’s speaker connections to the sub-woofer’s speaker-level inputs.

I am not sure which method is better. I called Music-Hall and the guy (maybe it was Roy Hall but I am not sure) told me "I don’t like sub-woofers... just do what ever the sub-woofer manufacturer says".

But the JL Audio manual does not specify one method over the other.

I am new to sub-woofers, so I was hoping maybe somebody on the forum might be able to help.

Thanks in advance,

Why not try both ways and see what sounds best to you? If there is an RCA out as you state, I'd go with that. 

That sub has no high pass filter,so anyway you decide to hook it up the speakers will still be running full range.
That's what I was wondering about, and why I tried the speaker-wire connection first.  I was hoping that if I used the sub in parallel with the satellites, that the highs and mids would go one way and the lows would go the other way (to the sub).

I guess that shows my ignorance of how these things work...

I connected it this morning back to the RCA R&L method and I guess I will keep it that way out of simplicity.

Thanks for the replies,

Eric
