View Full Version : Amp and Pre-Amp Head unit

04-12-2011, 03:12 AM
Hi, I'm new to this forum, and I don't have much knowledge about audio or how to set it up to get the best sound or quality, but I'm willing to learn!

What is the difference between Amplified head units, and Pre-Amplified head unit. My brother-in-law told me, "it's better to get a pre-amp head unit" I asked him why, he replies, "it's better because when you run the pre-amp head unit with an amplifier, it sounds so much better and you can tell the difference easily like day and night" He told me why but I didn't really understand specifically why and how to distinguish the technical part of that reply. Can you guys tell me what's up about the head units?

I think you a little confused here whats your goal your trying to accomplish? Just get a new head unit? Or get amp, headunit, subs?

Most headunits come with 2v rca preouts for amplifiers, and an amplified signal coming out of the wiring harness. a headunit that has preamps for rca's is nice because you can run the rca's to an external amp and run it however you want, plus there will be more power. most headunits only put out like 13w x 4

I'm trying to get the best sound quality when I set up a sound system for a car. If I get a head unit, I'm planning to get an amp to power speakers and so on.
