Having problems with the installation of the brutus 2008d amp in my truck. how many channels is it? how do i connect the subs? do i connect the rca cables from the radio to the input or output.

The rca cables from your stereo go to the "input" part of the amp. Now, if there are four speaker connections in your amp, then it's a 2 channel. If you have eight speaker connections then you have a four channel amp. Note, some amps can be briged to provide more power to the speakers. On a two way amp(2 speakers), the connections can be briged to only one speker providing more power, usually whatever the amp power rating is, say a 500watt amp will put all 500 watts to that speaker. The same goes for a four way amp(4speakers), can be bridged to two speakers(250watts per speaker). Hope this helps.

Free amp problems

As you are probably aware the red light would be the circuit protection.

If you are confident with electronics it could be worth repairing yourself as the component parts are reletively cheap but that depends on how you feel about fault finding and soldering or do you know someone who you could ask to take a look and possibly do the work for you.

It might be worth getting a quote before tossing it in the bin though.

Just bass through speakers attatched to amp

Check the power transistors which usually have their cases screwed to the main heatsink/body of the amp case. They are usually large black cases with 3 legs soldered to the main board.
If any of them are shorted out inside the amp will go in to protection mode. you can test them in the circuit but it's best if you can detatch at least 2 of the legs when testing. If you don't understand the meter readings for transistors you can test them with a continuity tester which will bleep if the transistor is shorted inside.
First put the two probes from the meter on to the first 2 legs, if it bleeps it's probably shorted in side, if it does'nt that junction of the transistor is probably ok.
Then try leg 2 and 3 and the same for leg 1 and 3.
If all 3 legs bleep which ever way round you do it, the transistor will need replacing.
Depending on the power of the amp there are 8 large transistors, 4 for each channel.
Good luck with it.
