Hey guys, I have a few questions about my system. So this is my first time changing out a stock audio system in a car with brand new parts, yes noobie here . The parts I have alrdy ordered are a set of Alpine type R 100 RMS (coaxial)6x8 for the front two speakers. For the back I have Alpine type S which are 75 W RMS(coaxial 6x8). I ordered a Sound Ordnance M-4075 amp which delivers 75 w rms to 4 channels. I also use an alpine cde 141 head unit.
So, im starting to question my choice of purchasing an amp with only 75 W rms, when i will be installing speakers that have a 100 rms rating. I have read that this can cause my amp to clip the tweeters heating them up and eventually blowing them out ("underpowering" them). Is this true even if I don't crank up my amp at all? In other words, if I just keep my amp at the normal settings (gains ect..) then my amp will not be sending any more power than it would be to my alpine type s's; which is why i bought the amp in the first place due to them being 75 W RMS.
Now, could I use 2 channels of the amp for my two rear 75 w rms speakers and then bridge the other 2 channels for higher wattage for my front 100 w rms speakers? I need to research more on bridging, but won't this make the impedance 2 ohms for the front speakers? Not sure how I would go about doing this with parallel and series. Any help here would be appreciated .
Lastly, since i alrdy purchased the amp I will be using it assuming it won't harm my type r's, would the sound really be that much worse when only 25 W under the speaker's RMS? Does anybody have experience with underpowering their speakers by 25 W rms?
I know I have many questions, just trying not to screw up my first audio installation and want to learn as much as possible before I start wiring. Thanks guys!
