Nice sound system questions
 

So in the near future i want to get a nice sound system and am trying to figure out how to go about wiring up an amp and such. Im getting rockford fosgate components in the front and coaxial speakers in the back. The fronts already come with a crossover in the package, But the speakers would be easy enough im just questioning the amp mostly. Im getting a 5 channel amp to power all 4 speakers and a sub, For the speakers i would have to run the wires from the radio to the amp? or are those what the rca cables are for? Also what is a good mounting spot for a mid sized amp? i was hoping i could have it in a factory fitted spot thats under the back seat but if it wont fit could i put it somewhere inconspicuous? i want it out of the way lol. then for a 99 cherokee with the sound bar grills those just pop out with a screw driver right? thennnnn im still contemplating on cutting a hole in my door for the speaker grills as by the looks of it the factory ones cut off half the speaker.

RCAs send the signal to the amp. Yes all speakers wire to the amps. Under the passengers front seat. You pretty much got it for removing the rears. I prefer a stealth install, but yes I also agree with the factory grill blocking some sound. Make sure that you use good wire. 12ga for speakers and minimum 8ga, preferred 4ga to the amps with a fuse box. Did you consider doing the big 3 ? Upgrading your battery and ground cables? If needed you can also install another fuse block under the hood. There are people in the selling forums that have what you would need. As for the head unit, hook up everything except the speakers. Good luck !

hmm well i went the cheap route with an old bazooka sub that i had laying around and installed my pioneer headunit (200 watt max compared to 40 max is a noticeable difference) and ik ik rms and all that old was producing 3 per channel and new one i think is 18 per channel its alot more punchy now and with the subwoofer i couldnt help but blast it alot lol. There is alot of things i gotta look at tho now that im getting a basic understanding of subs and that but the amp is a different one for me lol, I gotta get one now im craving more power but also im noticing a power dip here and there with major bass hits so ill be looking at an upgrade of the sorts but this was with high beams, ac on high and some led driving lights and a booming ass subwoofer and speakers lol. but this radio has a nifty feature that is handy it has a quick charge port on it!

edit: and yes im looking more at what rca does i was confused with this wiring harness the sub comes with it has high level and low level cords on it like the hell are these for. but seems its for factory radios
