new amp now tweeters wont work?????

[matt.gtr360]

Hi all.... I just replaced my old sony 4 channel amp with a new Audiobahn 4 channel but now my tweeters wont work... I put the old amp back in and they fired back up, so I put the new one back in and still no go again.. the old sony had no hi/low filter but the new Audiobahn one does... Could thes have something to do with it.

The amp is controlling the 2 rear rockfords aswell as the 2 front infinity cappas & tweeters.. I dont understand why everything runs sweet with the cheap old sony but the tweeters dont run with the new Audiobahn...... Any help would be great... cheers guys...

Has to be a crossover issue. Are there switches for high/low and full?

 

[matt.gtr360]

The cross overs have a 0db-?db switch on them. Sorry i cant remember what the db range is. I have flicked it back and forth but it did nothing. The amp has low/high/full - on low I dont really get any sound, High and full both produce sound but still nothing at the tweeter. I have played around with levels but doesnt fix it.

actually flicking the crossover from 0db to ?db changed the sound coming out of the doors a bit but did nothing to help the tweeters...

crossover on the amp, set HPF and at about 80hz

Do you have a passive crossover or at least a capacitor on the tweeters?

Crossover issue on the amp, check your setting again

 

[matt.gtr360]

Yeah checked everything twice. Tried every combination of setting that I can, Still no go. Pissed off, just cant see why they would not work.

bbeljefe::::: } The tweeters have crossover but I have no capacitors within the whole set-up...
