Question about Infinity 475A Car Audio Amplifier

Both Positive and Negative Speaker Wires Mixed With Truck On

My sons truck was running when he crossed the two speaker wires. The amp went into protect mode and went back to regular. Fuses are fine and so are the cables but you can hear engine noise when started. Whats wrong?

How do I connect my nitro 1000 watt amp to get thr most bass .i have two 15 vx kickers


If you have the Nitro bmw-482 running it at 2 ohms will give you the max output (its not 1ohm stable so don't run it that way). First run your two dvc speakers parallel (run both negative out puts together and both positive out puts together on each speaker). After this you should have 1 positive and 1 negative wire from each speaker (4 wires altogehter). This will give you a 1 ohm load which your amp can't handle, so you have to run the 4 wires in series to create a 2 ohm load. Now take the positive wire from 1 speaker and connect it to the negative wire from the opposite speaker. Thats how to run in series. Now you should have 1 positive wire from 1 speaker and 1 negative wire from the other speaker which is 2 ohm load. Your amp sould be bridgeable, so connect the positive wire into the correct terminal of your amp and the negative wire into the correct terminal of your amp according to where to bridge it (positive into left positive, negative into right negative) . That will give you a 2 ohm load bridged which is the most power you can get out of your amp 300 watts. Medium quality amps are over rated so you will never acheive the 1000 watts as advertised.
