AWESOME bro.... very cool... glad you got it sorted..... nicely done.... congrats.....
Yeah I need more midrange though. They keep up but the bass is still drowning it out. Should I go more power or just wire up another mid. ?
-
I just relocated the amp to inside the cab and took it off the side. I measured voltage to see if there was some crazy drop between power and grounds. And it stayed above 14.
The amp is literally brand spanken new.
I hope it was just some thermal issue or something to do with the impedance.
I'm still waiting on UPS to deliver my othe mids but lord knows if they'll get here before 4
honestly do they ever? im lucky if i get my packages by 6 or 7pm
Lol yeah it didn't get there until about 8 or so.
But I figured it out. Some connections to the other missing mids were touching and causing the amp to protect. So it runs good
I just didn't see the clips hanging into each other. Stupid things
Oh well. Works and sounds great. Thanks guys.

Shutting off at mid volume has to be an internal issue.
There's no way mid anything should hurt any amp. Mid to me means you can talk normally and it matches the volume.
I don't really know what to say other than warranty it or somehow get another amp to test (yes I know you don't have one, but it's really a good way to eliminate possible causes)
Your grounds are good, and by good I mean they aren't screwed under a seat so there shouldn't be an issue there.
Measure the voltage of THAT amp? I really don't want tot say its your vehicle, cause you know what your doing IMO.
I'm no amp pro or anything but.. Your electrical is good, rcas are good, speakers are good.. Really doesn't leave much.
Ohm load, or an amp issue is all I can guess

run a dc 175.4 and see if it dose the sameRight ... And then shutting off at mid volume..??? Hmm, anyway to find another amp, and slap it in??! And See what happens.???
i dont have another amp.
Nvm what the op said.lol
hope yall are joking.. i just said i didnt have another 4 channel
-
bump for any other opinions
-
ill see what happens tomorrow i guess. thanks

My first thoughts were connections or if it was mounted somewhere it couldent breath but nevermind lol
thats what i kinda think. its an extended cab. but the panel over the front block it off. its mounted inside behind the panels by the side window.
behind the seat belt area..
-
anybody else have any ideas?
-
ive got the bass blockers for the super tweeters coming in tomorrow as well as the other mids from crescendo. so i guess ill recheck my crossovers and see what happens..
-
As of right now all channels measure between 6-7 ohms. I find that weird seeing as how all are supposed to be at 8 ohm
some 8 ohm speakers, or 4 ohm for that matter, tend to read lower than stated. i've seen 8 ohm drivers on partsexpress that have an Re of like 5.something
okay well only the mids that are in right now are parts express stuff the super tweeters are crescendo and they read like 5.8 and 6.0
-
How did you tune the amp and what is your electrical like?
the amp is scoped. and honestly i dont know what the crossover setting is id have to look. my buddy set it and he does it all the time. and did it last time with no issues.
my electrical is a 3400 and xp3000 and mechman 270.
voltage doesnt drop below 13.9 at full tilt.
-
this starts on the passenger side of the truck and the power and ground run under the box to the driver side to this

I'm gonna be pissed if I have to trash this amp. It took them 3 months to send me another
-
It actually just went into protect again after 10 min of playing at a mid volume.
I don't know what the deal is. The amp is brand new
Edit: all I have to do is turn the radio off and back on. And it comes out of protect
-
no expert on anything here.. but is there any way,just to trouble shoot, go at the amp, wire the 2- 8ohm channels, to 4, and crank it up, and see if it stays playing? just to see?
Id rather not keep throwing it into protect
if I can figure out the problem without messing with it too much I'd rather do that
-
It's grounded to my buss bars. And I'll just wait until the other mids are in tomorrow to see what happens.
-
I've got an onx4.125
It's got 8ohm to each channel for the time being until more mids come in tomorrow.
But it'll play all day at low volume but when I go full tilt it goes into protect after a few seconds of playtime.
I felt the amp and it's pretty warm but definitely not toasty.
Any ideas why this could be happening. I'm thinking it's because te impedance is too high and just causing too much heat too quickly.
I'm not an amp guru so I'll take any advice.
Tomorrow I'm getting two more mids and it will have both front channels wired to 8 ohm which is the super tweeter. an the two rear channels which are the two mids paralleled down to 4 ohm
I had this on my previous amp which was the same amp just I screwed it up and the input signal was egged up. So they sent me a brand new amp and it's only had power for a couple days.
Need help guys. Thanks

if you can just make a box with an external port that is removable and try some different tuning . figure out what you like best and then make a real box with that tuning in mind.
-
theyre a musical box not a numbers box
basically itll play anything very nicely and can be loud on low power
-
I just want it to be louder than it is in my current box, i'm not looking for numbers at all, just something that continues killing the lows, but has a wider response range than my current box (first one i ever built, believe me....it is shitttt).
if you want a ground pounder and dont care about numbers tune low.. like 42-45 hz and have lots of port.
17-20 per.
my old 4th peaked at 33 hz. it was two 12s on 2k and it was great. didnt play much over 42 hz though.
if your feeling froggy go between 20-25 per on port area. but unless your design is good and know you wont have unloading issues id stay 20 and below
A ground pounder with simply 2 12's you sayyy. Haa, no, that's too broad of a spectrum for me, i dont listen to all songs with low ass bass, if so, id sure as hell tune lower...honestly, i was devise away to make the port swappable so i can try out what the different port tunings sound like on it and in my car without constantly having to destroy the box.
just used two sided foam tape for an adjustable removable port
you can do whatever port you want. doesnt need to be external. you cann do an internal port that can be removed

Yeah right now I set all my stuff using a multimeter, I'm looking into getting a good oscilloscope or the SMD DD-1glad to see we could help save you from blowing your subs apart, just remember to set your gains correctly. clipping on that 3.5k will fuck up your subs in a heartbeat
using a multimeter will not keep you from clipping. i suggest buying a dd1 or oscope.
if you plan on playing it before you have those then dont turn your gain up much and go off the clip light on the bass knob
4channel thermal issue?

Yeah right now I'm thinking another driver in a better position would help a lot. Seeing I have a wall the port is right by my head so I hear that over anything.
Buying another set of drivers would be a cheaper way because I have a space on side of the seats closer to the doors to fit another driver
