1999 Jeep Grand Cherokee Amp Power Draw Questions

[JamminJZ]

Hi Everyone,

I own a 1999 Jeep Grand Cherokee with the 98% of the factory Infinity sound system "amp and speakers".

I have installed a Jensen flip out dvd playing HU with i pod connection and the unit came with a AV connection pod that is hidden inside my center console that also hides the i pod connection.

My question is I would like to install a small 10-12" sub in a sealed box to add a little more low end but not blast out the windows. I listen to club, techno, rock, pop, country, well just about everything but rap and r&b.

My batt. gauge currently runs just a little bit below the dead center 14 volt mark so I am trying to figure out if I could add a small mono block amp for the small sub looking for probably no more than 300 watts MAX for the sub. I am trying to figure out if keeping the stock amp and adding a mono block would work or would I be better off taking out the factory amp and speakers and going with either q 5 or 6 channel amp and replacing all the factory speakers and if using a 6 channel amp bridging the last 2 channels to power the sub or what?

I know alot about pro audio systems but not so much when it comes to car audio.

I am picky about my sound quality and like warm full sound and occasionally when listening to techno or club having a little thump but not enough to rattle any windows or anything.

HELP lol

Any advice or insight would be great thanks,

Joe

if all you're trying to do is fill in the missing bass. I say go for a small quality monoblock and a 10 or 12 sealed subwoofer.

an Alpine MRP-M450 would do nicely, coupled with a Phoenix Gold RSD 12" or 10"

Amplifier

10"

12"

you will be fine... but just so that you know it takes allot to get zj's and wj's loud... i would for sure go with a decent lil 12 and the power it wants... your stock electrical will be fine... Your also regulated at like 13.6-.8v stock so dont worry about the voltage...

the alpine 450 would do very fine in that car...and the 10 inch in a sealed would be very tight ..but u like techno to...so i would go with a 12 inch sealed...and it shouldnt draw much at all..i have a 1997 escort that was running more then 2 amps off stock electical...and it ran fine

I had a boston acoustic g2 12 running off of an alpine m350 in a sealed box. I think you would be happy with something similar. I'd look into a decent reliable 12" that runs fine off of small power. The G2's aren't very expensive.

Find a decent 12", give it 300-600rms in the right box it should be more than enough.

As far as replacing all your speakers, that's your call.I was nowhere close to satisfied with the stock infinity system in my ZJ.Actually, when I got it all the door speakers except 1 rattled/buzzed.
