completely baffled

[ajax]

I put in 4 infinity kappa 5x7 2 way speakers a while ago and they have been good to me. Couple months ago I put in my new deck with 3 preouts and hooked up the 4 channel amp i got. A couple weeks ago I hooked up my subs to another amp. While I was driving around a couple days ago my front speakers just seemed to cut out. They haven't come back in yet, it is like my staging is backwards, the people are behind me. I played around with balance and fader and thought that I discovered that the tweeters went out because the bass was still pretty strong in the fronts, but it was just a whole lot clearer in the back speakers. So I just took off the door panels to see if maybe the tweeter wires on the external x overs came unplugged from the speaker, but they didn't, and I discovered the tweeters were working. Now I am thinking for some reason that the the tweeters, or maybe the whole assembly in the fronts isn't getting the same power as the back, but then why would there still be decent bass in the front and my first impression be that the tweeters messed up. And why would it do this when I am driving around? What should I check to see if it is broken, I really have no idea.

Try switching the RCAs around on the amp front to back. If the problem reverses its your deck or the RCa connections to it if Not Your amo is probably screwed up.

i switched the RCA's and when I put the deck to full front fader position, which is actually the rear, it still sounded good like before. When I put it to the rear (front) it sounded bad like before. You are saying it is the amp? Could it be in the speaker wiring for the amp? Like if something was grounding out, it would provide less wattage to the speakers, explaining why the fronts aren't as good as the rears? Or do you think maybe my speakers are broken up front, but that dosen't really make much sense that they would go out at the same time does it?

There may be one other suspect and that's your RCAs. If you can do a temp swap out with another set to see if anything changes. If nothing changes it's in the amp if it does change then you have a bad set of RCAs. After that its up to you to fix or replace stuff because that will pinpoint what the problem is.

well, I already did sorta do the swap when I switched front and back on the amp, the problem didn't move with the RCA's like if it was an RCA problem, it stayed in the front speakers regardless which set of outputs were used. So would this be a speaker problem, or a wiring problem, or an amp problem? How could it be an amp probem, like an actuall internal problem with amp, even though when I switch the RCA's it didn't switch the problem to the rear?

well, in that case, i think there's only two things that could be wrong..

1. front speakrs themselves

2. wires to the front drivers need replacement

My mistake..I Misunderstood what you meant by switching RCAs I was thinking that you had reversed them..
