Think I found out whats wrong with my SLC's

[Ruffy 10+ year member]

Well since I got them I wasent happy with the output. I was running them without a subwoofer what so ever off a Hifonics amp. The midbass was lacking completely. Still is somewhat but sounds better than before. Oh and my doors are deadened to hell. I have 20sqft of damplifier on each door. Front, back, inside, out. I'm about to put an order for some more for the rest of the car and some ensolite or overkill.

Anyway, last week I decided to reset my gains to proper levels so out I went with a DMM and set it to 20volts(100*4 then sqrt) Instantly the sound was improved(Seems i had my gains still fairly low) But something still sounded wrong.

I played with the fader and balanced and finally understood the problem. The left channel sounds completely different from the right channel. It sounds half powered or blown. The right channel sounds great. left sounds soft and lacking. I dont know if its the woofer, the tweeter or the crossover. To me it sounds like its the tweeter thats not producing much.

Could this have been whats been throwing me off and lacking midbass all this time? Any ideas on what I should do?

The tweeter output for tweeter didnt work on my x over at all, check your wires and whatnot, then make sure both are set to the same level like +0 or +3

Oh and play with the gains some more, along with the settings on the amp.

well 0db, -3, +3, and -6dB offered no audible difference for me

As for playing with settings. been doing that since I got them. Right now im quite sure the left tweeter is blown. Sound is still coming out of it. but not details and it's missing alot compared to the right.

Have you checked to see if both chs on the amp are putting out same power?

 

[Ruffy 10+ year member]

yep. Got them both to just slightly above 20v with my calculations.

I can try checking again later. I'll be tracing things

What does the resistance on the tweeter VC read?

I would start with playing test tones to determine what speakers are not playing they way they should. Just play one at a time until you figure out which one is bad. Then check the connections. Sometimes the terminal posts can wiggle loose and cause intermittent cutting in and out.

I'm at work right now but I'll def be checking the resistance first.

Switch sides on the crossovers. That will def rule out a crossover malfunction. I hope you aren't one of the people that like to put crossovers in doors. Def check the ohm across the VC of both the tweeter and the midbass if that isn't the issue.

no. crossovers are in the dash panel. I was going to have them in the trunk but I ran out of wire and didnt want to buy more. I probably will rerun wire down the road when I yank up the carpet and deaden the floor

check your voltages at the speaker.

component wiring can be a ***** + 2/3.

also, could be tweeter phasing

Could be the reason one tweet plays louder than the other.

I just send my slc's back cause something was screwed up in em. They blew 3 amps and no i didn't hook them up wrong so hopefully your not havin the same probs as i did.

Since when do speakers cause amps to blow up?

Ask that to my amps //content.invisioncic.com/y282845/emoticons/blackeye.gif.66a1670f5aaf7f406e783a63e3387dc5.gif they took quite a beatin.....and yeah i have no idea how it could have happened.
