Question:

how to wire a 4 channel amp to door speakers?

i know where the power,remote,rca,and ground go but how do i wire the speakers do i hook it up to the stereo or do i just take off the wire from the speakers and then hook up the amp to the speakers???

Answer:

Its not as simple as running speaker wires Most 4 channels are rated at 2 ohms and depending on what impedance your speakers are and how many you plan to power, you might have to wire them in series, series/parallel, or parallel. Speaker impedance usually come in 8 or 4 ohms.
A 4-channel amp is commonly under pressure the comparable as a outfitted-in head unit amp: Stereo, front and rear, left and correct. The amp will see the impedance of the put in audio equipment and perform at that load. maximum commonly, inventory audio equipment are 4 ohm, yet some 2 ohm at the instant are getting used. Assuming which you have a separate subwoofer and amp, someplace between 50 and a hundred watts RMS is in many cases sufficient for stable high quality factor or coaxial audio equipment. Alpine's lowest powered 4-channel, the KTP-445 Head Unit potential %., in basic terms outputs 40 5 watts RMS into 4 channels, yet even without a sub, it is going to grant sufficient bass to a pair of 6X9 coaxials to rattle the abode windows. With a separate sub, Alpine recommends putting the potential %. benefit to low. i might propose finding for a high quality amp in with regard to the comparable RMS potential selection as your audio equipment are rated to safeguard. that is probably okay to bypass a splash larger, incredibly with a separate subwoofer. That way, you may save the constructive components on the two amps quite low and nevertheless have sufficient quantity to play them loud.
Run speaker wire straight from your amp to your speakers. I am running 14 gauge copper speaker wire to all my speakers. Not the only way to do it. I have seen people running speaker wire from behind the dash to the amp [if you know what i mean] but i wouldn't suggest that. So just speaker wire straight from amp to speakers. Enjoy.
