Clio 182 rear speakers have a crossover? 🔊

[Jackie]

I installed some half decent JBL speakers up front and they sound great compared to originals. Very happy with the sound apart from door rattles....

So then I installed a second pair in the rear of the car and they sounded like garbage. (I have original head unit and used the settings to only send sound to the rear speakers)
Completely different sound to the front ones.

I then put originals back in and they sounded about the same. It's almost as if there's only 2W going to rear speakers rather than 20W or whatever it's supposed to be.

Is there a crossover or something causing most of the power at rear to be lost?

Would installing an aftermarket head unit solve this issue?

My idea was to maybe just split the front outputs and splice them onto the cables for rears. This of course would half the power but they are small speakers and go plenty loud enough anyway.

I did have a search and no one else seems to have discussed this.
Mucho gracias and merry Christmas 🎄

Don't splice 2 speakers in to one output, this halves the impedance; if they are 8 ohm then it would then become 4 ohms, this reduction in load doubles the current through the output stage of the amplifier and usually results in smoke!

Sorry I can't help with your problem.
Just out of interest. What speakers did you put in the fronts? I'm looking to change mine sometime.

I got JBL stage 2 524 speakers.

Very good sound. Managed to get for 27 squid Amazon warehouse offer.

It's like the rears are connected to same outputs as the tweeters or something.

Maybe the output for my rears is just bad. Head unit is 20 years old now TBF.

Bloody good point.

I just read that the front door speakers are connected to same output as tweeters apparently.
So I'm thinking the rear output is bad on head unit most likely.

It sounds pretty good with just front speakers going so I may just leave as is. Would have been nice to have a bit more volume and less rattling with 4x speakers going though.

Seems like your head unit is failing. An aftermarket head unit will sound loads better, plus you can have bluetooth audio and calls etc. A game changer in an old car

I think you're right mate.

It's a shame as I quite liked the stock look. I already have an aux input into back of standard unit using a magic box that uses the optional cd changer input.

All oem speakers are wired per channel and there is no crossover on the rears.

Stock head unit is also shite. A good aftermarket stereo vastly improves sound quality overall.

I actually think its the location/sound deadening at the rear. On my dci it was not specced with rear speakers so did not have oem wiring. Wired the rears direct to the headunit with quality wiring and still sounded shite. Speaker grill rattle like fook.

Bit of blue tack might help the covers rattling?
Or mammoth tape or something.

Not worth messing on with in all honestly. The doorcards also rattle once you fix the cover rattling.

Underseat sub is a better upgrade with a good head unit.

Got one you recommended?

This one fits and works well.
