LOC Issue?

[tlw1980]

Hello everyone. I've had an LOC running a cheap 4 ohm amp setup directly pushing two 12's for a couple years now. My amp went out, and I bought a nice Kenwood capable of 2 ohm setup. Ran it correctly, pretty basic, however, now I only get bass if I only have one RCA plugged in. If I plug in both, no bass. I'm stumped because I didn't change anything else except running the new amp, and I triple checked my positive/negative wire routing from the amp to sub 1, then to sub 2. Wondering if this is a common symptom of a bad LOC.

It sounds like a polarity issue. Since you checked the sub's polarity, I think it may be the RCA's polarity. Was the first amp a Mono and this one a 2 channel?

Yep. I'm gonna go out right now and toy with the wiring to the LOC.

Ok, so the input wires to the LOC, I can have one channel connected fully + & -, and connect one wire on the other feed to one specific side of the other LOC channel and have sound, but when I connect the second half to complete the channel, it cuts off. I tried switching them numerous ways and can't get any tried combos to work. So strange.

I think that still indicates that it may be the LOC is bad.

How are the subwoofers wired inside the box? Are the single ohm or dual 4 ohm or dual 2 ohm or what?

What Coolhand20th said. If the amp cannot handle the Ohm load of both subs playing, it will shut down. What are the make and models of the subs and amp?

I tried both ways, to trouble shoot. I have new news today! I bought a new LOC, went home and rewired everything carefully (2 ohm) and it all works! So, I guess the LOC did have a bad channel or something. I don't really know how they work. I wonder if it had something to do with my old amp quitting.

This is the first I have heard of an LOC causing this symptom. Thanks for rhe update.

I may have just got lucky and corrected another wiring error when I redid it all, no way to be sure I guess, unfortunately. Thanks for the feedback
