Set-up with two subs and an integrated amp

rbach +1
I have 2 REL subs and connect them via a 'speakon' high level input from my amps speaker terminals. I found this connection is by far the best way to connect a sub.  

OP:

I have a Line Magnetics LM-508ia and there are no line/sub outs. Can anyone help me out with possible solutions?

rbach:

I think the OP received great advice, REL has the perfect solution for the OP's problem.  mattmiller, wlutke, oldhvymec and lalitk all gave great advice...you are the one giving misleading advice.

Actually no, you must not be reading, because some of that advice is wrong. The OP does not have to buy a sub with speaker level inputs. He can simply do as both myself and imhififan said and use a LOC.

Question for you, rbach, you really think "the perfect solution" is to sell two subs in order to buy two subs? You really think that is better than a $20 LOC? 

Really???!

If your budget is tight you may want to try this subwoofer:

I've had one for about a year and I like it very much.
Very tight and musical.

Millercarbon,

That is wonderful information. Thanks. Why is no one listening? Oh, I know, they're too busy listening to  themselves.

I've noticed by some of your comments that we may have more in common than one would think. Besides a shared appreciation of the RSL 3600s I should tell you that I also go by SpdYlw993.
