help troubleshooting my system

[smidge710]

thanks, im going to go ahead and tackle that right now, ill get back as soon as im done. now dont the amps/headunit need to be tuned and whatnot?

Yes the amp does. Do you have a dmm (digital multimeter)? If not, get one. 10-15 bucks at walmart. Google "setting gains with a dmm."

 

[smidge710]

yea i have one.

 

[smidge710]

i do not know the specs of the amplifier im using though

 

[CSCStang]

I looked it up and it says 25wX4@ 4ohms. So you would run a test tone of 1khz with your volume at 75% (without the speakers hooked up) and the gain all the way down and your eq flat and all filters off on the amp. Hook the dmm up to the front speaker outs on the amp and set at ac volts on the dmm. slowly turn up the gain until you get 10volts. Then do the rear.

i see a lot of people say to use a cd, i currently dont have any blank cd's could i use an aux cord and my phone for this?

 

[CSCStang]

After you set your gains, don't go over the 75% volume or you'll start "clipping" the amp.

Yes, but a cd is best

sorry for all the noobish questions but you have been a great help. now which knobs on my amp are the "gain" and what are the filters on the amp? if i have any?

 

[CSCStang]

Gain is volts. Filters are on top...lp off hp. Set to off.

 

[smidge710]

sorry im still confused, the lp/hp switches dont have an off position only lp/hp or lp/hp/out. also the lp/hp knobs what do i need to do with those? anything?

 

[CSCStang]

Switch to out then.When you're done, go back to hp and adjust to where you like the sound best using the hp crossover knob.

ok so im not sure what im doing wrong, i got my power on, headunit on rca unplugged from amp, with a test track running at 75% volume and im getting no voltage readings

 

[smidge710]

ok well i definitely did something wrong, only one set of rca cables is working.. and when i plug these in in is controlling all sets of speakers exlcuding the sub.. i have rewired everything the way i was supposed to..

 

[smidge710]

well both sets of rca are working actually, but weirdly only on one set of inputs.. why is this? and they both control all speakers?

 

[CSCStang]

There should be a switch on the amp that has 2 channel/4 channel. It's probably on 2 channel still.
