Default Can I replace the stock Infinity Amp with an after market one?

I have searched and search to no avail. Sorry if there is one but either I suck at looking or one doesnt exist.

I have a 2010 Rubicon with the stock Infinity system on board. I want to make the speakers a little louder. The speakers don't sound bad nor do I really want to trade out the stock HU. Im not a fan of the way they look since the mounting kits all have the spaces on the side so keeping the HU would be nice. What is the best way to do this? Can I simply switch out the stock amp with an after-market one like this?

Any help would be great!

Get a PAC C2A-CHY23 this will allow you to add an aftermarket amp to your stock radio

Thanks for the fast reply!

Are there any downsides to doing it this way? Will I be able to mount this in the stock amp location? I chose a smaller dimension amp specificly for this. How would one choose the speaker channels to use.

Typically, the signal won't be as clean as if you had dedicated pre amps. Should work fine though.

What exactly do you mean? Sorry not huge in the car audio terminology.

Thanks.

Well you would essentially be tapping the speaker wires for your signal to feed the amp. an aftermarket head unit has dedicated pre amp outputs, often juiced up with more voltage for a stronger, much cleaner signal that isn't as prone to introduce noise and artifacts into the signal, remember the amps job is to amplify whatever signal you give it, so you want as high qaulity a signal as possible. I wouldnt worry about it so much for just a sub and amp combo but your mid to high range sound qaulity may suffer a bit. Especially because the factory headunits apply eqaulization to the signal feeding the factory amp and so in some cases you may not get a full range signal to feed your aftermarket amp in which case you may also need a signal summing device which takes all the fragmented audio signals and sums them together so you have a full range signal, it can get complicated. thats why most people upgrade the headunit when replacing a stock system.

You should check out the jlaudio clean sweep or the mtx re-q these may be helpful for your install and give you a way to retain your factory headunit, yet still build the system you want with new amps and speakers. These devices were made to help people do just what your trying to do but with great results.

Im thinking about changing out all my speakers to Kickers even the infinity sub and just installing the amp right under my passenger seat. But then i dont want it breaking from it getting wet or something, not sure if it would be a good idea to wrap it in something to protect it from the elements.

Thanks for the great explanation! I used to have a sound set-up in my old Sierra so I have an idea what your talking about now.

As far as the devices, are you referring to things like this and this?

Where would these fit in to the system?

Sort of my worry about placing one outside of the stock location. Worried about the elements.
