how many amps?

Hi,
I own a 2001 wrangler. It came stock with the sub-woofer built into the console.

I replaced the head unit and the 4 main speakers and now want to add some amps or maybe an amp. The head unit has 2 preamps (1 for the speakers and 1 for the sub). My question is, should I buy 2 separate amps, (1 for the speakers, 1 for the sub), or should I buy one of those amps that has the 4 channels plus one channel for the sub?

My main concern about the amp that does it all is that it doesn't plug into the sub preamp, only the speaker preamp.

I have never had an amped system before. Will the battery run down pretty quick if you are listening to the music when the jeeps not running?

The jeeps got a hide-a-trunk, the amps will go back there, Will it get to hot for 2 amps back there?

Thanks for all the help

I would go with 2 amps...make sure your speaker will handle the power of the amp you get. How much you want to spend may also change whether you get 1 amp or 2 amps.

I would do as suggested and get two 2 chan. amps, 1 amp for the front/rear speakers and bridge the other for the sub. This will make controling the sound quality much easier, especially if you have a sub pre-out you more than likely have sub woofer controls on the deck unit.

If you drawing alot of amperage (high wattage system) yes your battery will run down quickly, you can offset this with a capacitor or two and a good battery (I like Optima's).

Ensure that the amps have either internal fans, this will alleviate any over heating problems. I doubt you will have a problem in the hide a trunk, unless you seal it with dynomat or something.
I have a sub in mine (which is preamped) never had a single problem with overheating.

Good Luck!

On a small system like that your better off with just one amp. You will have less wirring and still have all the control you would with two. TJ's dont have the best sound quality and all that you would get out of two amps would be slightly better sound becuase the subs are not sharring the same power supply as the components. You wouldn't realy be able to hear the differance in that jeep. It will cost you less and will be easier to install a good 4ch. If you have a good battery in your jeep than it will usually take a few hours to run down the battery from a system this size. If you plan on running it while the cars off alot than get a optima and you problem is solved.
