2 amps

[Fender5 10+ year member]

I finally have two amps runnin. I'm using a power/ground distributer block.

4 gauge all around. 4 gauge as main, and 4 gauge to each amp. and 4 gauge ground

There was heavy there was some heavy interference but i fixed it after i moved the speaker wires away from the power wire.

The subs are weak for soem reason, and the front speakers do not work. The front ones are connected to the head unit right now becuase I am waitin on my components. Only the rear is powered by the amp.

Head unit only has 2 RCA outputs. Front & Rear

Im runnin the mono amp off the output of the 4 channel. It worked better

What could be the cause for the weak bass and front speakers not working

im assumin so. i need to redo it tomorrow. i spent roughly 8 hours getting it to work. stripping, crimping, cutting. redid my mono amp wires.

had a hard time gettin 4 gauge into the 4 channel amp even though it says 4 gauge recommended.

phase prob on subs

 

[Fender5 10+ year member]

do i just reverse phase to 180? or do i need to check the pos and negs?

pos and negs

 

[Fender5 10+ year member]

i'll make sure i check that.

the 6X9s came alive man! Never amplified speakers before. I can't wait to amplify my components when they come in. They actually rattled the trunk. Just barely

Now why don't my front speakers work? I disconnected the front RCA that i had going to it and still no luck

The back speakers also sound distorted past a certain volume. Are they blown or did i hook something up wrong.

thats called clipping. you need better speakers or more power.

Distortion isn't always clipping. The speakers have limits, too. It could also be that the amp distorts prior to clipping. Many budget amps do.

 

[Horsemanwill 10+ year member]

that's true there are alot of cheap amps out there that put distortion out quciker then anything. at the same time you should make sure the signal your sending is undistorted too as an amp just increases that distortion.

speaker says 80W RMS. but the amp is puttin out 75.

The front speakers do work. I faded it to the front, the rear is just so much louder.

Now the subs are not working. I can hear them, but they are weak and sound muddy. I've swtiched the outputs around. and everything

I did output of 4 channel to output of mono

output of 4 channel to input of mono

output of mono to output of 4 channel

wat is the correct one

 

[Horsemanwill 10+ year member]

just plugging and testing like that could result in amp failure. if the output of the 4 channel is a full range out put that would go into the input of the mono. then you would have to check the xover settings on the mono amp. does the 4 channel have an option where you can run all 4 channels with just 2 rca inputs? also check your gain setting on the front channels.

 

[Fender5 10+ year member]

yeah the 4 channel runs on 2 rcas. front and rear. and thats all my head unit has.

when i say 2 rca i mean one pair not two
