I want to connect a second amp to my car audio system. Could you describe to me how this is done. Do I need to run a second power cable exct. If I have already connected a amp. Where does the Line cables go?

Re: How to connect 2 Amps for my car audio system
Based on your post, you actually have 2 concerns: 1. Power - Normally this is the +12V straight from the battery + terminal. If the existing power wire from the battery to your old amplifier is capable of carrying the combined current (in Amps) of the current + the new, then it is simply running an extension of the B+ line (usually big red wire) from the old amp to the new amp. The negative/ground is simply connecting to the chassis/exposed metal part of the vehicle. On the other hand, if the old amplifier uses a rather not so big wire to supply it from the battery, you are better running another bigger wire from the same battery terminal to the new amplifier. You have to check how much current the amp will draw from the battery and select a wire that is capable of carrying that much current without heating up. Offhand a #8 AWG would suffice for most single amp.
2. "Where does the Line cables go?" If you are referring to the Line INputs of your new amp, they maybe connected to the RCA OUTput (line level) of the old amp (it it's got one). Alternately, if the old amp has only INputs and your new amp has both INputs and OUTputs, remove the RCA connection to the old amp and plug them in to the new amp. Thereafter connect another pair of RCA male cables from the output of the new amp to the inputs of the old amp. If neither of the new or the old amps has an OUTput RCA female, you may need to use a splitter of some sort. Below is an image of a two female RCA to a single RCA male.
You can hook it up in many ways. The simplest would be to remove your existing RCA connection to the old amp, plug in the double female/1male to the INput of your old amp. Connect the cable from the head unit to one of the female RCA. Connect another pair to the other female and the other end to the input of the new amp.
Hope that this be of some help/idea. Pls post back how things turned out or should you need additional information.

You didn't indicate what car your radio is in, whether the car has factory amps that the pioneer is integrated into or bypassing, or if you're using the radio's factory amps to power the speakers, or if you have external aftermarket amps fed from the radio's preamp outputs. So with the lack of information, it's hard to say for sure what's going on, but I would suspect either you have a radio whose internal amplifier is dying, or your car has an internal amp that's being overdriven because your pioneer's internal amp is providing a powered signal to your car's factory amp which should never be done. There's too many directions in which to go to troubleshoot this issue because you haven't said anything about the make and model of your car or it's current sound system, so I hope I've given you enough of a foundation to point you in the right direction.
Hello! The required voltage is 24 volts...which means two 12 volt batteries connected in series...It sounds as if you have two 12 volt batteries connected in parallel...Which doubles the amps and leaves the voltage at 12 volts...Connect the negative of one battery to the positive of the second battery...Then from the positive of battery #1 to the negative of battery #2 is the required 24 volts for the Kole...Guru...saailer
you dont want to connect both of those amplifiers together. You could run them separately to separate subs or the jl to your sub and your alpine to your front speakers. But you dont ever want to mix and match amps to the same sub. Even if you had 2 jl500/1's you wouldnt want to just hook them up together. Because they both have to be putting out the exact same amount of power. Which no 2 amps are ever exactly the same. Some companies make bridges to properly connect 2 exact amps together. I Hooked up 2 JL 1000/1's to each voice coil on a 13.5 W7 and i smoked the sub. So i definitely dont reccommend doing it unless the amps are conneccted to separate things.

Your amp is probably OK. The volume is either set to
high or the speaker load is to low of an impedance. Remember 2, 8 ohm
speakers connected is the same as 1, 4 ohm speaker. Another possibility is that
you do not have enough battery power coming to the amp itself. A simple rule I
use is take the watts and divide by ten, that will give you an approximation of
the amps needed on a 12 volt system. This takes into account some of the
losses in the amp, but it is only an approximation. For example 300 watts RMS
is 30 amps, which will require a number 8 wire to keep the losses at a minimum.
You can check wire drops on the web.
You either have a short, or the speakers are too powerfull for it, or the most likely problem is that your fuse is like 15 amps, but the amp is like 20 amps, so check the amps and if they are near 13 or higher, put in a higher rated fuse. :)
OK, From what I am understanding is that you both are trying to uilize a digital audio source (HDMI cables are digital audio only) and hence this is the problem. You can only use an analog audio source (connection) to utilize the audio output to zone 2. A simple soultion is to use the analog audio in conjuction with the digital. Connect the digital (HDMI, Optical, Coax) to the main zone and the left and right audios to zone 2.
heyman... try checking the fuses on both the sony amps. if they are ogood...next try hooking up each amp individually...if they will turn on seperatly but not at the same time it could be due to over abuse of the single ground and power leads that feed your amps. meaning that whie 2 amps will draw more power, they will also break down the wires faster. a continuity test of the power and groundwires should also be done.
