the difference between cheap and expensive pre-amps are the materials used lo. Good components give u less interference therefore, before the signal is transferred to the amps, very little signal or power is being "lost" in the pre-amp. I hope i have answered your question.


WHY USE A PRE-AMP? It's main function is to do some tuning which older models of HU can't do. I hope i have answered your question.

If you need any advice on buying pre-amps. DON'T BUY ANY. Just go ahead and get a good HU. If you are still not satisfied with the level of tuning the HU gives u, go for a Active-crossover.
