Brutus amp output problem

If you are replacing the existing door/deck speakers with replacements of the same size and not adding an amplifier, you will be able to use the existing wiring, making note of the positive and negative notation.
Subwoofers, on the other hand, require an amp. There are subs that have an integrated amp in the enclosure, otherwise you will need to buy a separate amp. Connecting the amp to your existing system will highly depend on what outputs your head unit (aka stereo) has. If it has pre-amp outputs, those can be run straight to sub amp. If there are not pre-amp outputs, you may have to buy a "high level" adapter that connects to the same head unit outputs as your speakers.

i would check the speaker cables to see if something came disconnected first maybe wire i touching other terminal shorted out the channels output .

run a new set of rca cable to see if one use are bad . check to see if rca cables pluged into right output of radio . check to see if your remote wire is powering up the amp to turn on the amp ..

will still light up with battery power but will never put output to the speakers with out the remote turn from the radio ... how to check this is to disconnect the cable at the amp and take a short 18 gauge wire and strip both ends and touch the battery terminal at the amp terminal one end the other end where the remote wire is mounted on the amp if do this for a few seconds to see what happens or better yet buy a digital volt meter and check for 12volt a the remote wire when you turn on your radio

run it all series and bridged

MAKE SURE SUBWOOFER OUTPUT ON YOUR RADIO IS ON IF NOT THAT COULD BE BAD INPUTS ON YOUR AMP

check to make sure your rcas are good, check to make sure all your connections to your subs are good and if they are most the time this meens your pre amp in your amplifier is out.

i would assume hooking it to the remote and ground of the amp

Possibly you need to return the amp and get a new one cause that could mean an internal problem and its deffective, you could try replacing the fuses or try changing the ground wire, this problem is very unusual

Have you confirmed that you have a good signal feeding the amp?

Have you confirmed that the speakers are in good working order and don't have any breaks in the wiring?

i think you could but before doing that did the amp itself send the output to the line if it did then replacing the parts would be pointless. if it was a hook up problem then replace parts and don't let it happen again

Hi,

Based on your post, you actually have 2 concerns:
1. Power - Normally this is the +12V straight from the battery + terminal. If the existing power wire from the battery to your old amplifier is capable of carrying the combined current (in Amps) of the current + the new, then it is simply running an extension of the B+ line (usually big red wire) from the old amp to the new amp. The negative/ground is simply connecting to the chassis/exposed metal part of the vehicle.
On the other hand, if the old amplifier uses a rather not so big wire to supply it from the battery, you are better running another bigger wire from the same battery terminal to the new amplifier.
You have to check how much current the amp will draw from the battery and select a wire that is capable of carrying that much current without heating up. Offhand a #8 AWG would suffice for most single amp.

2. "Where does the Line cables go?" If you are referring to the Line INputs of your new amp, they maybe connected to the RCA OUTput (line level) of the old amp (it it's got one). Alternately, if the old amp has only INputs and your new amp has both INputs and OUTputs, remove the RCA connection to the old amp and plug them in to the new amp. Thereafter connect another pair of RCA male cables from the output of the new amp to the inputs of the old amp.
If neither of the new or the old amps has an OUTput RCA female, you may need to use a splitter of some sort. Below is an image of a two female RCA to a single RCA male.

You can hook it up in many ways. The simplest would be to remove your existing RCA connection to the old amp, plug in the double female/1male to the INput of your old amp. Connect the cable from the head unit to one of the female RCA. Connect another pair to the other female and the other end to the input of the new amp.

Hope that this be of some help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.
