hello

i have 2 components in my car 2 speakers front and two speakers in the back doors

front speakers are 70 RMS and back speakers are 50 RMS

they are connected in the same channel as 2 ohms

when i turn the music loud, back speakers make bad noises

what can i use to seperate them??? transistor? capacitor?

thank you for reading

You should have those separated already instead of paralleled together. Right now you are trying to use more speakers than you have amplification for. As soon as you can afford to, separate those pairs and put them on their own amplification at 4 ohms. You'll then have controls, crossovers and gains to fine tune them individually, and the amplifier will be outputting at a higher quality into 4 ohm rather than into 2 ohm.

For a temporary fix now, you can put in high pass filters on those rear speakers to keep out some of the damaging bass freqs that is making them sound so bad. See the help section on the left column... Passive crossovers, high pass filters, 4 ohm chart, 250uF non-polarized cap. Solder the cap into the + wire as shown in the diagram.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Use your amp to power the fronts, and use your radio to power the rears.

My ex once told me I have a perfect face for radio.
