audio set-up for beginners [continued]

Siento,

You can't bypass the DAC of the head unit as long as it is analog. For example, we have a Pioneer 80PRS and a Alpine H800 processor. The chain is Pioneer 80PRS -> Alpine H800 -> Amplifiers -> Speakers. But since it's analog connection or via RCA plugs, the source is still modified/affected by the Pioneer's DAC. Only way you can bypass the Pioneer's DAC is if the signal is purely digital like from binary CD data (0s and 1s) directly out of a digital output (SPDIF/digital coaxial).1

I am actually assuiming that the headunit of the swft has an optical out, like mine. Also, if the signal that passes through coming from the HU goes analog and then passes through the DAC of the processor. The processor's DAC will prevail.

DSP idol. Like our AVRs when we use a BD/DVD/media player, it has it's own DAC and it goes through our AVR. Yun lang, difference with external processors sa kotse, it does not have a pass-through option.

So hindi po advisable mag stock HU>DSP>amplifier na setup? Plan ko sana to install a processor in the future dahil limited lang capabilities ng HU ko and ayaw ko rin palitan HU ko dahil sa TPMS, GPS and etc na mga features.

ah ganun pala yun hehehe
mas madali pa yata sa ht kasi walang mavoid na warranty hehehe

btw mga bros sa experience nyo ba after a year of use na OK ang electricals ng auto, is it safe to say na OK na sya imod to upgrade the sound setup?

If you will have it installed from a reputable and reliable shop, i dont see anything to worry about. First thing i do with a new car is modify electricals (sound set up, lights, etc.) and i haven't had any issues so far (3 cars na so far).

Depends on the head unit, but take note that a lot of stock head units has filters built into it. Unless you have a way in bypassing the filters, you'll get sub-optimal sound.

Still, the term is "sub-optimal", for many.. the inclusion of a processor and tuning is still a leap ahead.

Audison processors have a De-Equalization feature. I think that is an important tool for HU's with unwanted filters.

When I got my new car, it only took me 3 weeks to see if anything is failing. Afterwards, I started modding the sound system. Didn't have an ounce of regret. Happy with the sound setup. Kaya upgrade na natin yan idol
