Hifonics Txi 4008
 

So I just installed a Hifonics Txi 4008 for my front component system and I'm not sure what to set all the dials to because I've never amped a front set of speakers before so any help would be great! Here a link to the amp hopefully.
Hifonics Txi 4008 Amp: 2-Channel

Keep your crossover switch in High Pass (HPF), your mode switch in stereo. Put your bass eq knob to a quarter clockwise turn starting from 0db, turn your high pass filter knob one quarter counter clockwise turn starting from 1.2khz, your low pass filter knob 1/3-1/2 clockwise from 30 hz. This will be a good starting point, you will have to listen and adjust stuff lightly as time goes by to get the proper sound you like. As for the level knob, keep it at the 5v point, turn your cd player volume up about 80%. Then start to slowly turn the level knob until you hear distortion then bring the knob back a little bit.

So I did all that and it sounds good.... but when there is no music playing or between songs there is a buzzing coming from the amped speakers. So is it a bad ground? bad speakers? or what?
Thanks for your help

it sounds like an rca prob. try grounding your rca to the back of the deck, any wire wrapped aroung the tip of the rca to the back of your deck will do.

K cool thanks

I wrapped wire around the female end of the rca in the back of the deck and then wrapped it around a screw in the back and it didnt help. Could it be the quality of the rca's im using cuz im using just some crappy ones?

could be. could be a slice in one touching metal, could be a bad amp ground aswell.

Ok well i swapped out the rcas and they still buzz, i checked the amp ground and it is good so any more ideas?!?

I can give you other thoughts, what is the amp mounted to? where is your speaker wire, power wire, ground wire ran?, near any stock wiring? Does youre deck have any frequency tuning capabilities on it?

So I was just out there fiddling around with it and found something helpful out i hope.... when i change the x-over from High Pass to low pass the buzzing goes away, when i change it from low pass to full the buzzing comes back. So that leads me to believe that its not a wiring problem or an amp problem but a problem with my component set. Any new advise on how to fix this now?
