Do I need an Amp for this set up???

maguirre · 09-24-2009, 10:26 AM

Hi all,

I'm currently running this set up in my 1997 Supra w/o issues:
Pioneer Premier DEH-P940MP
Fronts Speakers - Infinity Kappa's 42.5i "4"
Rear Speakers - Infinity Kappa's 652.5i "6-3/4"
Subwoofer - JL Audio 10W3v2 with JL Audio 250/1-250 Watt Amplifier...

Now the problem is with my 2000 4Runner.
Here's what I plan to run in my truck:
Pioneer Premier DEH-P980BT
Fronts Speakers - Infinity Kappa's 652.7i 2 Way "6-3/4"
Rear Speakers - Infinity Kappa's 62.7i 2 Way "6-1/2"
Subwoofer - JL Audio 10W1v2-4 with JL Audio 250/1-250 Watt Amplifier

The problem is that when I hook all this up my rear speakers go out.
This makes me think that I may need an amp for my front and rear speakers.

If I do, please let me know which amp is best for this set up.

tia,

maguirre

Multi channel for sure, I run a 6 channel to power 1 set of 5.5 components 1 set of 6.5 components and 2 10's.
As for amps these are all very good top of the line
Rockford Fosgate
Phoenix Gold (I have the xs 6600 very happy with it)
PPI

Those Infinitys should work fine without an amp. I'd say you have a different problem.

You do not need an amp for the speakers to run,you have a problem elsewhere. You will get benefits from amping the front however.
