Question about Cars & Trucks
I have a 2005 GMC Envoy and connecting an audio system. I have everything installed but i dont know where the control wire that comes from the amp has to be connected. They told me i had to connect it in one of the ignition cables but i need to know excactly which one! PLEASE HELP ASAP
It's always blue wire in back of radio. You could connect it to ignition power but amp will always come on when key is turned on. With it hook up to radio the radio itself will power the amp. But again its blue remote wire if you can read the labels still on radio

SOURCE: Hooking up speakers to amp
YES ! This is usually ok, the speaker cabinet should contain a high pass filter or crossover on the tweeter to decouple it from the low frequency signals. My Linn Index speakers are wired like this.

I'll try to help you step by step from your question. My answers will be in all caps. Here we go.
I really hope u can help me,i have 2 basic speakers with connections in the back for the amp leads to go into,but i am really struggling with what wires i put into the amp and in which connections and then really, really struggling with which connections i need to come out of the amp to go to my speakers.
I have a Carlsbro 150w power module
(THIS SOUNDS LIKE A PA AMP AND NOT A CONSUMER STYLE AMP, IS THAT TRUE?)
and it has an Output hole of which im guessing is where the speaker connection goes
(IF IT IS LABELED OUTPUT THEN IT IS INDEED A SPEAKER OUTPUT CONNECTION)
,but on the front of the amp i have 6 channels,each with a hole which is black that says HIGH Z,and also a red hole that says BALANCED LOW Z,
( THESES ARE MICROPHONE AND OR GUITAR INPUT JACKS AND MOST OFTEN YOU WOULD USE THE HIGH Z (meaning impedence) INPUT FOR A MICROPHONE
and next to it i have two buttons with REV and FX
THESE ARE FOR REVERB AND EFFECTS CONTROLS OR INPUTS. YOU DON'T NEED THESE FOR JUST A VERY BASIC SETUP.
.At the other end of the amp ,ive got another red hole that says REMOTE SWITCH
DISREGARD REMOTE CONTROL SWITCH JACK
and 2 black holes that say EFFECTS ,SEND and RETURN.Do i need these?
DISREGARD THESE TOO
I just dont know where to put my output line from my mixer to the amp.
IT WILL GO INTO THE BALANCED LOW Z INPUT, BUT IT MAY ACTUALLY BE TOO HOT A SIGNAL(signal strength too high), LOOK FOR SOMETHING LIKE A TAPE INPUT OR SOMETHING LIKE THAT ON YOUR FRONT PANEL. IF YOU DON'T HAVE ANYTHING LIKE THAT THEN YOU MAY NEED TO USE AN ADAPTER DEVICE THAT WILL KNOCK DOWN YOUR SIGNAL STRENGTH TO THE RIGHT LEVEL FOR A MICROPHONE INPUT AND THEN PLUG IT INTO THE BALANCED LOW Z INPUT.
PLLLLLLLEEEEEEAAAAASSSSSSEEEE HELP.Im tearing my hair out.
HOPE THIS HELPS. GOOD LUCK

Tech data sheet with diagrams:
In a nutshell, the controller would go between any preamp Stereo OUTput and a dedicated amplifier INPUT. You really don't have much choice in the matter. The 802's and their controller are part of an inseperable system.
The Bose 802/901 family uses full-range speakers instead of traditional woofer/tweeter combinations, so they compensate for the response limitations at the extreme frequencies by using severe electronic modification of the program material. Hence, they are a system, functionally inseparable, but the results are outstanding. Consequently, they need a dedicated amplifier so they alone get the processing provided by their electronic component.
I don't have any data on your mixer/amp but if you can't insert the conroller logically between the mixer and its amps then you'll have to get separate dedicated amplification for the 802's, with the controller between the mixer and that amp.

It's not that this amp isn't like "newer amps" with + and - terminals, it's that this amp is made for public-address system use. This kind of amp is used in a store, for instance, to pump background music through speakers all over the place. The terminals you connect to are determined by total impedance of the speaker configuration used.
Most single speakers, or the two- or three-way cabinets for home stereo systems, are 8 ohms. If you're connecting a single speaker you use the "common" and "8 ohm" terminals on the rear panel. With multiple speakers, you need to figure out the total impedance and use the appropriate terminal. In series, impedances add. Two 8 ohm speakers in series would total 16 ohms, so you use the common and 16 ohm terminals. In parallel, the total impedance drops. Two 8 ohm speakers in parallel total only 4 ohms. You need to figure the total impedance of the speaker configuration and connect accordingly. Too great of a mismatch will damage the amp or speakers or both.
You might be able to find the manual for this amp on Radio Shack's website. Here's a link to the manual for the model MPA-40 which should have similar output terminals. The basic information about figuring out total impedance and general use of PA amps applies to your amp as well.
