there is a physics law that states that if any 1 single device in a circuit draws more than 20% of the total output of the source then damage will incur to the source. so really you need to take the rated amperage of your alternator and determine what 20% would be. then any amp that does not exceed that number will not hurt your charging system. personally I would use the JL amp if you know it is in good working condition

search up the amps your looking for in the search box in the forum search bar, im sure there are alot of opinions on here of pretty much every amp out there

The rd and saz amps are both good amps I would ask if the rd has been repaired and if so what was done

He say only 2 years old still look pretty clean from the pics i didnt ask if it was repair before but suppose to go test it out later on today..so u think that amp is pretty powerful n good? I saw a few clips on youtube but never heard of them or no anyone that has them i wonder how are the qaulity..

you also need to consider the sub and what its power handling capabilities are as well as what type of box you are going to use as that will directly affect the subs power handling capability

The sundown will be a better fit for the dibs. But if your planning in better subs then the rd amp
