Speaker Impedance : 4-8 Ohms High Pass Filter : Selectable on/off at: 50, 60, 80, 100 or 120 Hz.
High Voltage Pre Out : 4 Volt pre-out
Loudness : Dynamic Loudness
Low Pass Filter : Selectable on/off at: 50, 60, 80, 100 or 120 Hz.
Output Power (4ohm, 1kHz,16V)(W) : 52 watts x 4

Amplifier model number: Sony XM-ZR704
700W max power, 70W x 4 RMS into 4 ohms, 80W x 4 RMS into 2 ohms, 160W x 2 RMS into 4 ohms, variable 50-300Hz HPF/LPF on front and rear channels, Band : Low Pass Filter: 50-300 HZ, -12dB/oct High Pass Filter: 50-300 HZ, -12dB/oct

Power Handling Capacity : 500 Watts
Rated Input : 85 Watts


Front speakers model number:Sony XS-GTX1642
Frequency Response : 50-23,000 Hz
Impedance : 4 Ohms

What I want to know if I can connect the 2 front speakers directly to the MEDIA RECIEVER and 2 rear speakers to the AMPLIFIER OR just connect all 4 speakers to the AMPLIFIER without puting any damage to all of this stuff. Also, how loud is loud in a small 4 door car (2011 Toyota Corolla)?

well im going to give you a little although this belongs to car audio,
You have a 4 channel amp, just use that to power your fron and rear speakers. No need to use the unit to power the speakers. Wont damage anything.

I looked at the Car Audio section and most topics are about "what fits where and how to connect what" so I figured I would get much usefull answers here since this thread has much more related topics about my issue, but feel free to move the post if it needs to be.

If connecting all 4 speakers to the amplifier at 70W/channel, wouldnt there be a problem with the speakers that have 85W rated?

i dont think there would be a major problem in a car environment. Those speaker are ok eficient and the amp should do the job. In any case, if you listen loud then you may want to add a sub later adn run all front and rear all hi passed so you dont have to worry much underpowering your speaker.

So I finally installed everything yesterday. One problem: The installer did a great job mounting and wire connecting but he didn't tune the amp. I myself have no idea how to do it and a friend of mine said correct tuning is always different depending on hertz specs of speakers and amplifier.
My question is how do I tune the amp based on above specifications?
"Filter" "Level" "Low Pass"
The way it's tuned now I notice that when adjusting the equalizer on the receiver by setting it all low I still feel as if the bass is high and the high frequencies are high.
