Default Found some old speakers and now I have some questions!

I was going through one of my closets and stumbled across a pair of MB Quart 5 1/4 with competition crossovers that I have long forgotten I had, my old hobby........

Now my question is, what is the story with a factory Infinity stereo? I don’t have the budget for a new head unit, but am going to fit these into the dash. They will show the amp (is there a separate amp for the speakers on this system?) 4 ohms, what is the factory speaker load? Can a separate amp be added to the system and still keep the factory head unit? Is there any issues with hissing or hum doing so? I think I can still get ahold of one of my old PPI Art series amps, my brother has 2 that I know of.... to do this. Also, does the factory unit have any type of crossover? Does it use RCA’s (or some kind of line level outs) or speaker level outputs?

I know, tons of questions, but it has been a LOOOOOONG time since I have dabbled in car audio. Honestly, I like the sound of the system in it, it is loud enough, and the clarity is OK, imagining is OK as well, for a Jeep. Nothing is going to sound like a live performance or a good home system for that matter, but a serious improvement will happen if carefully planned out. Plus, I LOVE fooling with this stuff!

Seriously, any advise will be greatly appreciated, this is going to be fun! Thanks, Matt

there are no RCA's in the factory unit so i used an RCA line converter for my subs wired into the factory subwoofer after the factory amplifier (I believe) and it sounds awesome! Hope that helps and i believe you can just plug your speakers in to the factory wiring and it should work fine

since you have the Infinity system they will be getting the factory amp power so they should sound better than factory if they are not too old...

I think they should sound pretty good, they have never been installed, and while the stock speakers aren't bad, I feel these will sound better, I just need to get out and install them! The specs are decent on them and I have used MB's in several systems, but this was all back in the late 90's, I know there are probably better speakers now, but these are paid for.

Someone did a write up on the factory amp awhile back. Do a search. The factory sub is a dual 2 ohm voicecoil sub, I have a feeling the other channels will be the same. The MB Quarts would sound way better though

Thanks Ryan, I have been looking and yes there is a couple great write ups on this. I agree, the MB's will sound great, but now I'm thinking about going a little bigger, new HU, amp, new sub....... another mod for my Jeep!
