Car Stereo Question

[SwiftWind]

When I turn on my stereo, the sub amp's power light will come on, but the kicker logo does not come on. When I disconnect the signal wires, the kicker logo lights up and the amp is now running. If I plug in the signal wires again, the kicker logo light goes off, but the power light stays on.

Specs:

120.3SE - 400W at 4 Ohm

KX400.1 - 200W at 4Ohm, 400 at 2Ohm.

Since the amp is providing only 200w, would this be the issue?

Ideas?

Thank you in advance.

Sorry for being a newbie...

Edit: Took it to a car stereo shop and they tested it, its broken...bleh

Does it work??

No, no sound comes out.

Edit: Speakers in the car work fine, and they run off a different amp. Its just the sub and the sub amp that are having issues.

Did you wire it up right? The power ratings have nothing to do with it working or not. Did you hook up the remote line? It needs +12V to signal the amp to turn on.

By signal wires, do you mean the RCA inputs from the head unit, or the speaker-level outputs to the subwoofer itself?

Yeah. I ran 12V positive to a power block, one wire goes to the 4 ch amp which works, and one goes to the sub amp.

Signal wires - RCA inputs from the head unit going to the input on the sub amp. The sub amp does have output ports, but isn't that for hooking up another amp?

Yea, the RCA outputs are for chaining another amp off it - they may or may not be stereo.

Stupid question.... is your sub output turned on? Another thing to try (if you can), chain the sub amp off your 4ch amp and see if it works that way. If it doesn't, the amp might have an internal short and need to be replaced.

Possible short in signal wire from head causing a fault condition in the sub-amp, turning
on protection circuitry. Are you running 2 sets of pre-outs,one for each amp?? Try (if possible)
and switch with the pre outs currently running 2nd amp and see if sub works correctly

 

[SwiftWind]

well, amp turned out to be broken...ugh.
