Which amps to go with, the Alpine PDX or the Rockford Fosgate Power Amplifiers!?

Question

I finally got my ride almost where I want to be! However I think I might be having buyers remorse, but i haven't installed my amps yet! I was wanting to know since I am doing a 2 amp configuration! I have currenty in the box the Rockford Fosgate t400-4 which is for my front components and rears, and T1500 for my 2 /12" Rockford subwoofers! Keep in mind I haven't put this in yet! However this Alpine series the PDX has got me really intrigued the 4.150 which is 100 watts continuous power at 4 or 2ohm, where as my Rockford Fosgate is only 60 at 4 ohm! Then they have the Alpine PDX1.1000 for the mono which is 1000 continuous watts! I think my Rockford Fosgate breaks down like this T1500continuous power:
500W x 1 @ 4-Ohms RMS
1000W x 1 @ 2-Ohms RMS
1500W x 1 @ 1-Ohm RMS
So did I make a bad or good decsion by listening to the car audio people! I hear the PDX amplifiers get hot, but they put out so much power it seems for soemthing so small! Or am I simply underestimating Rockford?

Thanks for the quick reply, here's the answer to your question my 2 subs are the Rockford P3D412 dual 4 ohms, RMS/ Peak: 500 Watt /1000 watts! I got a set of MB quart signature component speakers in the front and the DTF-169 in the rear!

Answer 1

whats the rms and the ohms on your subs???? if i knew that it would be easier to answer

edit: as far as the amps go if your speakers can handle 100rms i would go with an amp that 100rms, but i wouldnt go with the rockford or alpine. i have nothing against rockford, but they are overpriced. and i dont like alpine. go for mtx. they are great amps and the new models even have an led setup built in that u can set to different colors to match whatever you want and gives you a lighted look without having to add neons. for the speakers id go with this http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=15179
as for subs im not sure yet till you give the rms and ohms of the subs

edit: you can wire each sub to 2ohm or you can wire them 2gether down to 1ohm. for amp id go with this

wire the subs to 2ohm and the sub has 2 inputs so u can connect each to the amp instead of going to a 1ohm load and u push the full 1000rms

Answer 2

Rockford Fosgate T400-4

Answer 3

You are underestimating Rockford. Rockford Fosgate always rate their amps in RMS instead of peak watts, meaning that a typical amp of a given wattage will only achieve about 71% of the stated power of a Rockford Fosgate amplifier, of the same wattage.
If the amp gets hot, it is being over-driven for the load it is under and not sufficiently powering the speakers.

Answer 4

Go ahead and put them in. Listen to it. Are you gonna save a bunch of money by switching to Alpine or are you just thinking 'more power'?
See how it sounds and go from there.
PDX are class d therefore DO NOT get as hot as a class a or b (regular topology).
How does it sound? Is it what you want? Plenty of headroom? Go from there.
Good Luck!

Answer 5

Fosgates are awesome.
I'd go with Rockford.
