Replacement of existing car 8 speakers sound system

[shutterbox 202]

Hi all,

After driving Forester XT a few years, decided to upgrade the sound system.

Factory setup is Harman Kardon audio system. Only info I can find about the set up is as seen + a factory head unit. Don't have specs of amp other than it being a 8 channel DSP amp with 440W output.

Usual music types, classical, vocal, Jazz. Not really into EDM. Fat Boy Slim is far as I go.

Thinking of 3 options to upgrade:

Option 1 - Keep factory HU, Harmon Kardon 8 channel DSP amp, wiring, and replace the 8 drivers at:

1. Front L/R door 6x9" woofers
2. Front L/R 80mm midrange below windscreen window
3. Rear L/R 80mm midrange at the door
4. Rear L/R door 160mm woofers 

 + add basic sound proofing.

For this, would need recommendations on what to replace, and at where.

Option 2 - Keep wiring (where possible), replace all HU, amps, drivers in a passive setup + basic sound proofing. Need recommendations on what to change to for a set up to support Android Auto and Apple Carply.

Option 3 - Do Option 2, but in an active setup. I'm just being playful where, but how much more are we looking at to go for a 2 Way active setup.

What kind of money are we looking at for Options 1 and 2 for a 2 way setup?

1k to 2k+ (depending on parts to change and their quality?), I think i can 😀. Not prepared to dump more than 3.5k though 😏

PS; I did some background searching here, hwz ICE thread, sgcarmart, FB, etc  but so many brands and setups it gets very confusing 🤣

Must be careful that the speaker depth fits the window else cannot wind down window.. the glass contact with the speaker magnet

The DSP amp is tuned exactly to match the position of the speakers, the power output and tonality of the speakers.

There is no way you can improve the sound by changing the speakers without retuning your dsp.

Tuning is a hassle.

My advice is don't change.

Position/power output an position, I think DSP tunes this to set the sound for Forester's cabin.

Tone, I think DSP doesn't know how to measure right?

DSP do tone also.

The DSP can sent say music that is 3k Hz and above to the tweeter sounds like a man singing

or it can high pass higher and send say only music that is 4k Hz to the tweeter

and sound like a man signing with his balls being squeezed. 

Very clearly it will be a very different tone.

If anyone needs a demo I can also call my MIL along to help with the squeezing.

I will never stop anyone spending money on car audio as I also love spending money on car audio

until my wife says I spend toooooo much money on car audio.

You can certainly change to better conponent speakers but you will have to retune your dsp

unless the speakers you change have exactly the same specs as your current speakers.

Now if they have the same specs then they will well sound exactly the same and no improvement.

The dsp is tuned to make your existing speakers sound the best it can be. 

So you cannot get a better sound but you can tune your dsp to get a sound that you like more!

What is it you don't like? More bass, a sweeter treble?

More bass add a subwoofer, a sweeter treble rolls off the high frequncy on the dsp.

If you want to change all your speakers you can. If you like the new sound then job done.

If you don't like the way the new speakers sound then you have to retune your dsp.

If you retune and still don't like it then you have to change to a better dsp and or change the head unit.

And after all that its not guaranteed that you will get a sound you like more.

The existing dsp is tuned to get the best sound from your speakers and the shape of the cabin.

Its designed to make the best of everything it has.

Now Pandemic no more concerts try to get some big concert speakers on the cheap and put it in your Musso.

Maybe something like these speakers would be good.

And once you get everything done the way you want. It’s time to change car.😂. And then the whole process starts again.  To some it a hobby.

After spending sometime checking stock speakers specs, I think I'll try to go for a FR for front dash n 6.5" mid that goes to around 50hz.

So far seems like audible physics has a FR driver that physically will fit front dash with minimum mod. 

Anyone has recommendations for other FR drivers around 2.5"?

i did my 3way active mixed Morel+Focal setup in XV (upgraded from initial 2way passive Morel with GroundZero DSP amp) at Dimension Audio, maybe see what Roy can do for you.

he's good at tuning and carries multiple brands to suit budget and setup and most importantly, what sounds good to your ears (cos different brands really sound differently). 

Hear it at his showroom to believe. he's not pushy also.
