PPI art A404 wiring questions/help

[tx4wl]

Ok I have looked at many manuals and cant get an exact answer as to the possiable wiring(s).

Im looking to run stereo front 2ch and if possible 2 rear subs(jl 8w3's)..can I do this? if so ..HOW? basically im not sure between what the manual says....

"the Front and Rear channels of your (four channel) Art Series amplifier are capable of

of being bridged into a mono output due to the internal design of the amplifier. This feature

permits the creation of a mono channel for a subwoofer or center channel. Also bridging

adds flexibility of operation. The Art Series four-channel amplifiers can be used as 2 mono

channels, 3 channels - 2 channel stereo and one channel mono, 4 channels - 2 channels

front and rear, 5 channels - 4 channels stereo and one channel mono, or 6 channels - 4

channels stereo and 2 channels mono."

....maybe a diagram will help //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Thanks guys The reason I want to try this is to test the amp,its old And want to see if she can still deliever what i remembered it could do 15+ years ago on both its LPF/HPF sound reproduction and to see if i can notice any degrading that may have taken place for being 20 years old (caps etc..)........ but have forgotton the proper way to do so

The problem is that the A404 will only drive 4-ohms when bridged. You have two 4-ohm subs, which isn't a good match to this amp. You have a few of choices, but none are ideal:

1) Use channels 1 & 2 to drive the Fr-Lt and Fr-Rt speakers. Bridge channels 3 & 4 to drive *one* of your 4-ohm subs.

2) Use channels 1 & 2 to drive the Fr-Lt and Fr-Rt speakers. Connect one sub to channel 3 and one sub to channel 4

3) Use channels 1 & 2 to drive the Fr-Lt and Fr-Rt speakers. Bridge channels 3 & 4 and connect the subs in *series* for a single 8-ohm load.

All above options will produce sound and not overload the amp. Options 2 and 3 will probably not drive the subs hard enough. Option 1 may actually be your best option because the amp will drive the single properly matched 4-ohm sub pretty hard bridged.
