50 Watts x 4 Built-in Amplifier

• 6-Channel / 4 Volt RCA Output

• Subwoofer Volume Control

• Built-in High and Low-Pass Filters

Okay guys, based on this, disconnect everything running to the amp and run the RCA outputs? I have an amplified bass canon in the trunk to hook into the subwoofer outs..

HU supposed to be delivered tomorrow so thought I'd get the ducks in a row

Clarion U.S.A. | CZ501

 

That should do, just the clarion is not symmetrical (sorry, my silly aesthetics preference) , and clarion used to have not the greatest FM reception, let us now how it is with this one.

You do need as described to add cinch inputs to the stock amp, the wires behind the radio are single stereo.

 

Well just did a straight up harness adapter wiring for now to get the HU in and start playing with it. Sounds great compared to the stock infinity. Volume settings go to 40 on the unit but anything past 30 starts getting distorted, but is still louder than stock unit. Reception seems improved also, local/DX was defaulted to DX and was picking up OK City (75 miles out) loud and clear. Blue tooth works great.. wife says no problem hearing me with built in mic. Planning to separate amp wiring for rear outputs and running bass cannon to rca on HU. Only downside I've found is my phone wont share the phone book-missed-last dialed with the HU. So it is manual dial till time for AT&T phone upgrade.

 

This makes perfect sense to me, and I am about to go ahead and do it. The Kenwood unit that I purchased has 3-2.5 volt preamp outputs, not 4.0 volts. Is your preamp output 4 volts?


Can anyone else tell me if it would be a mistake to do this with only a 2.5 volt preamp out? As I understand it, the front speakers would not be affected, only the subwoofers. This would be different from Airscape's setup.

I can exchange the unit for a different one with 4 volts, but it will cost $70 more to get the identical features.

 

If you plan on driving the Infinity amplifier with the pre-outs, you will need 4v.
You can always drive the amp with the speaker outs, you lose just a little clarity.

 

You could just use the speaker leads for the rear channel of the head unit (that is what I did on my coupe).. I don't think anyone has been impressed with the less than 4v output rating.

 

That sounds like a reasonable idea, but it might not provide as much control over the subwoofers as I would have if they were wired through the subwoofer preouts running at 4 volts. I think I am leaning toward exchanging my head unit for one with 4 volt outputs. I might as well do it right the first time.

 

Yep.. I used my "sub out".. for my amplified bass cannon..

 

YOU HAVE GOT TO BE KIDDING ME!


I hope the A/H 'cruisers' in my neighborhood don't see or buy these.

LOL.. it will rattle the license plate for sure.. And unplug 2 RCA leads and the wiring harness.. and it's outta there for packing up on a road trip.

 

I have a new Kenwood HU with 5V pre-outs. I currently have this wired with a standard wiring harness as supplied by Crutchfield to only the front HU outputs. After I make this change and separate the Front and Rear channels I assume the volume should be louder than it is now. Because I won't be sharing the front output anymore to drive all the speakers. Is that correct, will I have a louder system? I hope so, it could use a little more volume. Even if not, I'll probably still do the change to get the advantage of crossover control.

 

Not louder, as the amp is already driving the speakers in four channels, the change is to drive the AMP with the HEAD with four channels - giving you a fader control.

If your head unit supports it, you could also have separate equalizer controls for front and back, which is what I really want.

 

I would think because I provide 4 separate inputs to the amp, instead of the 2 inputs I currently provide that the volume would be increased. My thought is that because the input signal isn't split between front and rear amp channels it should be stronger for each input. Not that the amp output is changed, only the input supplied to the amp.


And I do have a lot of equalizer control in the HU so that is a bonus.

 

You answered your own question: "Not that the amp output is changed."

That is it: Power delivered to the speakers is a function of the amplifier, not what is driving the amplifier. It will SOUND different and (IMO) better, but not louder.

 

I wired my stereo using this diagram thanks a lot. I got like 3 random wires still. figured out that enable signal was the remote wire for the amp.
What is the power rating on the stock amp in the crossfire anyway?

 

 

Not sure if this is directed at a single post.. but at the young age of 51 I managed to wire my coupe to four channels with this thread.

 

 

You missed post 2?

 

Is post #2 accurate? There was a noted correction in Post #7. But I don't know if the OP went back and changed it or if a later diagram is correct. I was considering doing this change also.
