Also if you are running the power cable and the leads down the same side this some times causes a noise known as engine noise try running them down either side.

Without hearing the noise, it's difficult to determine the exact cause. I've seen enclosures do this if the panels were not glued together well.


Try connecting the speaker to one channel at a time to see if one particular channel causes the problem.

Can you bridge 2 4 ohm kicker speakers to a mtx thunder 7801 amp?

Ya. Just hook one sub to your amp (bridged) and hook the other sub (positive and negative) to the first subs positive and negative

MTX thunder 304 4ch red amp light comes on but no audio have triple checked all connections and they seem alright

if the lights on and there is no sound it's either a cd player issue or your rca issue or the inputs for rca's on the amp are no good. or you have your subs wired at a wrong load to your amp and it is in a constant protection to avoid burning up.

I'm having problems getting full power to my sub.

when bridgeing an amplifier it always sees half of whatever load you have on it, so if you have a 4ohm speaker when it is bridged the amp will see 2ohms, so yes you can bridge the 4 ohm speaker

sounds like you need another amp, if the amp has a speaker already connected to each channel, you have no open channel to connect a sub-woofer.
Some years ago I seen an amplifier that was designed to use 3 speakers on 2 channels. what they did was had a speaker on each channel and then they bridged the 3rd speaker across it. That amplifier was designed for this configuration, unless you have an amplifier like that you should not try it. It may result in smoke from the amp.

Jbl gto 3501 amp

It's a mono amp. There's no bridging with this amp.

The two pairs of speaker terminals are connected together internally. The second set of terminals is for convenience.

Subs will go off the wall with bass, but not in tune with music.

hi, first disconnect the rca input, then switch on headunit and if the amp produces a constant bass thump it then means it has an internal fault. if the amp idles quietly then replace the rca cable, or try connecting the headunit lineout feed directly to the bass amp, in this way you cud find out if your fault is coming from the headunit or the equaliser. cheers
