Lets narrow it down.

You've go two speakers, one works, one doesn't.

First off, switch the connections on the speakers.

- Good to bad
- Bad to good

Now, if the one that wasn't working, starts working: The speaker is OK

If the one the was working, still works: The Amp is OK

If the one the was working, stops working: Either the amp input for that channel has been compromised (check connections), That side of the amp is blown, or possibly (long shot) the heads balance is all the way to one side.

If they both are working: It fixed itself!!

Hope this helps locate the problem

I have 2 solo baric l7 duel 4ohm subs and a legacy la-2499 amp.What is the best way to wire it up?


Unfortunately, the amp is only 2 ohm stable, so the best option is to connect each subs voice coils in parallel (2 ohms) and connect the subs in series (4 ohms).

Open your speaker box up most likely the jumper from the inside of the box to the subwoofer itsself is broken free, Usally when they have lights around the sub woofers there seperate leads, bet 10-1 you have loose wires inside the speaker box

Legacy audio LA590 car audio amp protecet mode


Is that on all the time or are you saying the light is on? If that light is always on that just means it's protecting your amp. If it's off and not playing bass then your in trouble

I have 2 kicker cvr12s and a legacy predator 2400 watt amp and when I turn the radio up the amp goes into protection once they hit a decent time. I just down graded from 15s so I know its not a power...


you prolly have the subs wired to a too low of an ohm load...thats what happend to me. i had the same subs, and a 500.1 watt amp...and they still blew up..whire EACH sub to a 4 ohm...that should work.
