Now that you have the specs, I say go shopping for an amp with this spec:

4 channel, around 75 watts RMS @ 2 ohms / channel. Higher wattage is not necessarily better but make sure you get a 2 ohm rated amp.

Ones to consider:

JL XD400/4

Kenwood Excelon X450-4 (matches up well with both the front and rear power requirements of your speakers)

Kicker ZX350-4

Alpine PDX-F4

Alpine MRP-F300

Audison SR-4

and bunches more...I just listed the ones I have experience with. Currently running an Audison in the SRT and a JL in the truck.

Thanks md...
I like that Kenwood...am I gunna need any wiring harnesses or adapters? This probably needs mounted in the trunk, eh? This looks a bit more complicated than swapping out speaker....

Since the upgrade is to replace a stock amp with an aftermarket unit, will need to slice into the vehicles loom, from the factory end terminals where it plugs to the stock amp located under the dash. The colour coding is necessary to know which wire is what. Not sure if you will consider oxygen free wire, will involve a fair amount of work though, i.e. running new wires to speakers and new power cables. Oxygen free wire will lower resistance and will improve efficiency

Wiring in the amp won't be too hard. An LOC will be a lot of help. A line out converter, or L.O.C., is a device that turns the speaker-level audio signal in a car audio system into a line-level signal that one can connect to an amplifier. This is necessary when one is adding an amplifier to a factory head unit, since factory head units do not have RCA outputs to get signals from. Typically, L.O.C.s come in two and four channel versions for a variety of installation options, and may be easily removed to return the vehicle to stock.

Here is a good link on wiring up amps from the power end to the speaker end.

That is a great how to...thanks for that. Once I get the amp, I will post an update!
