How to connect mey speakers to the amp?

Since you have Only one common main output,you can hook up your speaker, its either in series or parallel connection depending on the impedance in your amplifier,impedance in OHMS,(8ohms/4 ohms/16 ohms) please see the impedance level at the speaker terminals of your amplifier,
Thank you,

your speakers are of an incorrect ohmage, or you have too many speakers hooked up to it. your stereo likely calls fo a singler 4 ohm (4?) speaker per channel and the factory speakers may be lower than 4 ohms, or you have several speakers hooked up to the same channel. there should be 4 channels, each with no less than a 4 ohm (4? ) load. two 4 ohm speakers wired to the same channel in parallel (both attached to the amp's poositive/negative leads) will create a 2 ohm (2?) load, and overheat the amp. if the 2 speakers are a woofer/tweeter combination, and there is a capacitor involved, it may be ok, but 2 woofers, or a woofer and a subwoofer hooked to the same channel will likely reduce the ohmage below 4 ohms (4?). look at the back of each woofer speaker, and look for an ohmage rating stamped to the back of the speaker magnet to verify that they are 4 ohm (4?) speakers, and verify that only a single 4 ohm speaker is hooked to each channel. the car likely has multiple speakers hooled up to each channel, which would lower the ohmage rating below 4 ohms (4?).

you need to run the left speaker output from the amp to the left speaker input on the Bose, the right speaker output on the amp to the right speaker input on the Bose, the center channel output on the amp(assuming it has one), to the center channel input on the Bose...then the right output on the Bose , to the right Speaker..the Left output on the Bose to the left speaker...and finally the center channel output on the Bose to the center speaker

You are correct

spks in p = lower than the rating of one

spks in s = greater than the rating of one

so 2 x 8ohms in p = 4ohms

and 2 x 8ohms in s =16ohms

Make sure that you do not connect too many speakers to the amp, and try to stay as close as possible to the amps specs.

Hope this helps, thanks for using FixYa

This is miscatagorize as a chainsaw; not the amplifier that it is. I requested it be moved to the proper catagory. It didn't happen.

Pretty Straight Forward get a 8 or 4 gauge amp wiring kit.

Run your hot wire to the +12V from the battery make sure to install the supplied inline fuse near the battery don't connect to the battery until installation is complete.

Run the REM to your stereo power ant. Wire. if available.

Run the GND to Metal Chassis Ground keep it as short as possible.

Run the RCA Cable from the back of the Stereo to the RCA Inputs or Low Level on the amp.

This amp is 2 Ohm Stereo Stable which means you can connect 2 (4 ohm) speakers in parallel to each channel or 1 (4 ohm) speaker on each channel or you can connect 1 (4 ohm) Speaker in bridged mode.

There are other speaker configurations you could use but you cannot drop the load below 2 Ohm in stereo mode and no lower than 4 ohm in bridged mode.

Hope this helps

double up the speaker and then use the two extra screw to hook sub and center

If you have a 4 channel amp and 4 speakers and each speaker is connected to each of the 4 channels you are just fine.
A stereo amplifier has 2 channels, typically labeled left and right and each channel has an amplifier. A 4 channel amplifier has 4 amplifiers. With one speaker on each channel, there is one speaker on each amplifier. Audio amps are referred to as amps or amplifiers, although if they have more than one channel it would be more correct to call them something like 'multi-channel amplifier' or 'multi amplifier speaker driver'. Semantics.

If you've got a standard 4 speaker system (2 front, 2 rear), your best option is to connect both left speakers to the left channel amp output and both right speakers to the right channel amp output. The only thing you lose is the ability to fade the speakers front to back.

WAT BRAND SPEAKER AND RECEIVER?POSSIBLE OHM ISSUE?WAT IS THE IMPEDENCE ON THE AMP AND CENTER SPEAKER,.HAVE YOU TRIED RUNNING A 6?8 CHANNEL CONFIG?FOR EX.USING YOUR SOUND CARD THROUGH THE PREAMP AS A DSP. WHE PLAYED IN SHOP HE USESD CD? U USING SAME CONNECTION FROM THE SAME INPUY? OR IF LISTEN ING TO RADIO. SOMETIMES THE SINGNSAL IS NOT IN A DIGITAL FORMAT SO THE PPR LOGII C CANT PRODUCE IT.IT WOULD BE PLAYED ANALOGICLY.MEAN NO CENTER.
