Wiring Loudspeakers to stock 2002 Jeep Infiniti amp

I have an old guitar amp whose speaker has an amazingly deep tone. The original head on it **** the bed and I swapped it for a 15w fender practice head and it still has that tone, so I'm thinking of trying to wire the speaker sans head into my stock 2002 Jeep Grand Cherokee Limited with the Infiniti Gold stereo package. I think this amp is 15w per channel? At any rate the speaker can handle it and sound good still. Higher is fine as the original amp head was 90w. It was a KMD GS90D. It came to me a couple years ago, I'm not entirely certain what is stock and what isn't in the unit. Info on these is almost non-existant. The speaker looks slightly different from other similar units, and bears no markings so I'm not sure of its Ohm rating or brand. Internet first series: View attachment 26555683

I'm wondering how I would go about this. The rear speakers already only get lows, so could I just splice it onto a rear speaker wire from the amp?

I'm not opposed to cutting the two rear speakers out entirely as they aren't very loud and don't add much to the sound anyway, to allow for more power for this speaker.

I'm not really looking to make this into some sort of super bass rig, just add some loudness and tone. I don't have money to drop on subs or aftermarket amps so that is out of the question.

 
I don't see how its such a bad idea, just putting a different speaker than what exists in the vehicle. It runs off the same power that is provided and produces a much better sound than the installed speakers. I don't see how it "won't work", signal is signal. It's going in the rear of the vehicle still in the amp box just being wired to the speaker not trying to go in the 1/4".

Heck, if it doesn't work then at least I'll have my splices in place to feed the aftermarket amp when I do finally get one.

There is always some evil denzien(s) of Caraudio.com who are gonna tell you "It just will not work" like it won't turn on at all, which of course is BS!

Try it out and see how it works! Then come back here and slap the face of the nattering naysayers of negativism around here!!

Of course use only the practice amp's speaker, none of it's amplifier circuits which probably run on 120VAC anyway, which we do not have in most cars.

most guitar amps use an 8 ohm speaker, car audio is mostly 4ohm. some amps support lower impedances but most factory systems are not very tolerable to using a load that is less than its designed for. if you splice into the factory wiring it can cause a load the fac amp cannot handle and break things. if you disconnect a factory speaker and use the leads to drive that speaker in the cabinet it will most likely work, but it will probably half the output from the factory amp if it was driving a 4ohm speaker that you replace with this 8 ohm load.

guitar speakers are make to drive a specific range of frequencies specifically for guitars, they are not made to reproduce the full spectrum that full range speakers are designed for.

Now this is an excellent explanation. Much better than the troll from Texas who can't spell "really".

I get the fact they are designed to produce certain frequency but the frequency response of this speaker is exactly what I'm after to beef up my stereo as this speaker adds some serious balls to my guitars. I'm talking home shattering low end bass players seek.
