1) Since the 800PRS HU has 3 way crossover and also a mini processor for active crossover, I then would do as you said on connecting the tweeters directly to the amp's front channels and the mids...

I'm trying to bi-amp myself the SR6500 comp with the pa500.4 amp, having the PRS800 as my HU. I have the following questions:

1) To bi-amp, is it necessary to eliminate the SR6500's passive...

Good explanation regarding the functioning of both brain hemispheres. I will certainly commence my setup with the numbers recommended from MacLeod, and from there I would tune with my right brain...

Yes it helped, it's good to know that with the 800PRS head unit I can highpass and lowpass at the 24db adjustment. So, since I would tune my system with all those crossover settings suggested by...

Thanks arun1963! Let me see if I understood you well. If the 800PRS can give me a max of +/- 12db, then does that mean that I can't achieve the tweeter highpass MacLeod recommends of 4KHz@24db?...

Thanks a lot MacLeod, for your valuable insights. Now:


And how exactly can I keep the mids on free air? If I install them on the 6.5'' stock location from the car's front doors, would the be...

This thread has been most helpful for me, considering that I'm about to install the SR6500 into a Jeep Liberty, and the Venezuelan car audio installers are very pathetic.. they only know how to throw...

^^^ No insights onto that?

I just purchased exactly the same system you got now, a SR6500 and the pa500.5. I'm curious on how much do you got your gains set to. I would like the most from the amp without frying any driver.

The Cadence ia4 is unavailable in the local market,but judging by its specifications, it seems to be a solid quality amp. However, I'm pleased to announce that my local provider of polk audio brands...

Do I take into account the driver displacement simply by adding up 0.14 cu. ft. to the total enclosure volume? That's all? No internal additional manipulation needed nor anything special at all?

Easy man, I meant it will probably be very positive.

I'm not sure which is the ia4, I'm googling it and can't find the amp. Give me the complete model name

Well that was enough for this topic. I will go with Focal Solid 4, since also I can get if for half the price than JBL's.

So that's it, my highs and mids will consist of an SR6500 comp, powered...

Hey, I found something interesting about the focal solid 4.

If you go to their main website http://www.focal-america.com/, and browse through their products to find that amp, you can see in their...

I'm also under 30, but lol, why do you ask? People over 30 can listen less to higher frequencies that what younger people do?

Well you're kind of right, sometimes I exceed too much when taking decisions..

A local provider of polks told me I was lucky enough and he can sell me one pa500.4. So I must choose between that...

pa500.4's frequency response is capped at 20khz. Wouldn't that be limiting the SR6500's upper frequency range potential?

I could find availability for the pa500.4 for roughly the same price as the JBL GTO1004, but I can buy only one unit of that polk amp.

So, it would be between the polk amp and the two focal solids...

Can't I just get 2 focal solid 4 amps and do the following:

connect the 1st 2 channels from amp #1 for mid #1 , for a total of 150 rms
connect the rest 2 channels from amp #1 for mid #2 , for a...

A tweeter wants 75 rms, but a mid wants 150 rms, so how can I compensate for the missing power to the mids? With a Focal Solid 4 I can't do this since they send 75 rms per channel.. but the JBL sends...

Wow I initially was thinking that bi amping the SR6500 to a focal solid 4 would be too much, since I would be sending 75 rms to each driver, while each side from the SR6500 is supposed to take 125...

Yes, but I was talking in terms of rms only, not of peak watts. The SR6500 has 125 rms per side, while the amp delivers 75 rms per channel, for a total of 150 rms per pair of channels.

So I could...

Ok, if Mac doesn't post here I will pm him. But what did you mean exactly by 150w per component and not driver? I mean, the SR6500 has 125rms per side, being 250 rms total. I interpret this as the...

JBL's specs are
Power Output 100W RMS x 4 Channels at 4 Ohms; 150W RMS x 4 Channels at 2 Ohms; 320W RMS x 2 Channels at 4 Ohms

But the focal solid 4 has 75*4 rms @4 ohm. Can't I use 2 channels of...

Thanks Arun1963, but it seems you have not read the whole thread. I will repeat the first fragment of my opening post:

I got two SR124-DVC, the Mb Quart DSC 1500.D amp to power them, and the...
