Badd ground ? what do bad grounds do?

[iivan 10+ year member]

i just connected my 4 channel amp

(2 channels to 6 speakers (my 6x8 my tweeter and my 3.5)

(2 channels to my rear 6x8)

i think i have a bad ground cause i see the amp light dim a lil with my highs on only

after about a full song it sounds like the amp isnt putting its full potential

can i be the ground?

im running a 4 Gauge Bullz audio amp kit( low end amp kit) to my battery which is in the back

what are effects of a bad ground? are some grounds better than other ground places?

How/where did you connect your ground?

 

[goingdef 10+ year member]

you have most likely dropped WAY below rated minimum impedance on the front two channels.

It's not a ground issue it's most likely incorrect gain settings along with the fact there are not many 4ch amps that will run around a 1ohm load per channel and if they will they get hot fast and require a lot of current to do it at all. My Rf T600.2 will run at 1ohm per ch(or 2ohms bridged) for about 30minutes then it overheats, he needs to wire the speakers properly or use a x-over to disperse the signal to the 3 speakers in each door.

^^^^ yep, sounds like too much load on the amp

Oh and one more thing on the 3 1/2s can i just dissconnect it? or do i have to remove the whole wiring

?

just pull and re-wire and check for in-line x-overs on the tweets.

View attachment 26534666View attachment 26534666Ok i dissconted those 3 1/2

so now just running my 6x8 and my tweeter with x over on the 2 fronts

it still does the same it powers down a lil and makes my highs sound like a radio

this is how my amp is tunned

 

[goingdef 10+ year member]

do you own a dmm by chance?

 

[iivan 10+ year member]

No, What is a dmm?

You think the amp is defective?

im so confused

 

[goingdef 10+ year member]

#1dmm =digital multi meter

#2 might be?

I would try hooking up one speaker to each channel and see what the result are but without the dmm(15.00 at walmart)it's hard to say.

 

[goingdef 10+ year member]

are you running comp type x-overs or just a bass blocker type and when this happens are the tweeters going down in output and then returning when the volume is reduced?

 

[iivan 10+ year member]

Ill go get one soon! ive seen people on youtube use them to tune amps

yes the speakers are connect to each channel no bridge

the only x over i got are the ones that came with the tweets

These

Kenwood KFC-T207 13/16" 280W Component Tweeter Pair 267-4351
