amp and sub newbie questions

okay, so I have a 2006 wrangler rubicon and I want to add some bass to my factory stock system. My first question is if I add an aftermarket amplifier like the Kicker Zx300.1, to power a kicker 12"inch enclosed sub, do I have to replace the stock amplifier that's powering my speakers and center console sub? or can i leave that stock stuff alone and just add to it with the kicker amp and sub?

secondly, do i have to buy a new head unit to hook my kicker amp and sub up to it? or can i keep the stock unit without interfering with the stock wiring from the factory speakers and sub?


all the help i can get would be great

youi can leave the factory equipment in there. now you will need to do a couple things.

1) you will need a line level converter to change speaker wire over to rca's to feed the sound signal to your amp. part is normaly about $30+ for a good one.

2) make sure when you use that line level converter you connect it to either a sub/full range signal. and also it's in phase (as in r+ is connected to r+ etc etc). if you hook that up to a tweeter, for instance, your sub won't do anything since the signal is alrdy crossed over to not play any bass.


with that said a new head unit would be a much cleaner sound signal and in alot of cases give you nice features like sub control and i-pod/usb hook ups, which are great if you plan to go off-road

another thing when you tune the system start w/ your factory stuff 1st. set bass @ 0 (in some cases lower) then see what volume you can turn it to w/o any distortion, then adjust the sub to that point. that way you can make sure @ that volume you'll be fine. biggest issue ppl have is not hearing the distortion once bass is added bc it will mask the factory stuff and w/ road noise and top off will make it worse. thats why speakers blow up so easily.

in my 95 wrongler i have a full system, 6 mid's & highs and a single 12" sub. i have had it for over 6y and never blew a thing up bc i know the limit of the system and don't go above it even it i feel the need to

hope this helps some .. feel free to ank any other questions, i work in stereo industry

you are best off getting a new headunit. right now crutchfield has a great headunit for an amazing price, i have one and payed full price. it has everything you will need to build a system in your jeep.

Pioneer DEH-P6000UB CD receiver at Crutchfield.com

Listen to Jma...I just bought that Pioneer and it is great. It drastically improved my sound quality and I haven't even changed out the factory speakers yet (working on getting those next). With the wiring harness and installation kit from Crutchfield, you're getting an incredible deal and it's a breeze to install. I don't have much experience putting in electronics and this was simple. I keep my Jeep in the garage at home and don't have to worry about it too much at work but when I'm out, I just pop the face off it it and either take it with me or toss it in the wife's purse.
