This is my first time ever installing a sound system, so excuse my inexperience and lack of basic knowledge. Right now this is the setup in which i have bought to install into my car. My plan is that the 4-channel amp, which is rated at,4 ohms: 50 watts x 4 chan, will power the 2 sets of speakers i have. The 3-way Sony speakers run at 75W RMS, and the 2-way Lanzars run at 60W RMS. I underpowered the amp rather than overpowered them, idk if that was a good idea or not, if someone could tell me whether im an idiot or smart for doing that itd be much appreciated. The 2-channel amp will be bridged to run at 400W RMS and power the 350W RMS sub. I have a couple of questions.
1)is it okay to have a pair of 2-way speakers conjoined with a pair of 3-way speakers on one amp?
2)My head unit only has one pair of rca out ports, and i have 2 amps, how can i get both amps hooked up to the head unit? and do i need to have one of them on a high level input?
3)What are high-pass and low-pass frequencys and do i need to use them on either of my amps?
Any help is gratefully appreciated!
