I have a 3400 watt amp for subs a 1200 what amp for high 2 tweeters and a crossover, how do i wire them?
3400 pyle mono amp, 1200 nitro 2ch amp, boss 2way crossover
how do i wire the 2 amps and the crossover
i know how to wire all the speakers tweeters and subs but completely lost on wiring the amps and crossover
Seems to be some confusion about the actual wattage use of the amps.
You need to work that out and figure out the actual needs of this system.
You can use one battery feed for both amps, you just need to size the wire big enough to handle the combined amperage of both amps.
You can do the same for the ground too, size it for the total power and tap both amps from the same wire. To do this you will need a bug or splitter lug. You can get these in set-screw style at home depot in the electrical section. The object is to combine three wires at one point. You would have the battery positive, then a wire to each amp coming together, and this connection needs to be solid, and insulated. You can wrap it in electrical tape to insulate a bare lug. Don't put multiple wires under the same set screw. That would be asking for trouble later. If you need to you can simply bolt multiple lugs together. Or you can crimp eye hole terminals onto each wire and bolt those together then tape them.
And the crossover is usually unpowered, And connected in line before the amps. Don't put an amplified signal through the crossover. It really isn't necessary to use the crossover on the 3400 amp, only the tweeters where you want to isolate the 12-20khz range. So your radio signal will first connect to the 3400 amp, and there should be parallel connectors on the amp to wire from it to the cross over, then to the 1200 amp.
Again, total wire size is according to combined max amperage (current) of both amps. Make sure you size the fuse at the battery on that wire the same as this total).
Google "wire ampacity" to get this information. Sizing the speaker wire is the same concept. Divide watts by (12) volts to get amps. And most people don't know that 12 volt systems have a voltage drop over distance, so every 6 feet you can lose up to a volt. So consider that you may actually only be getting 11 or 10 volts at the trunk which increases amperage.
For example 1200 watts /12 volts = 100 amps
but 1200 watts / 10 volts = 120 amps
If you're truly running a combined total of 4600 watts... then you would have 384 amps of power which is gonna kill your car battery and alternator. And you'll need to run some big ass aluminum for that, so on second though home depot won't have big enough lugs, you'll need an electrical supply house like rexel or hagermeyer. That's 500 Kcmil copper or 750 kcmil Aluminum. Very expensive stuff.
I hope those other answerers are right about these amps being way less power.
