Descent Amps?

[NJTStang11 10+ year member]

On another site I am trading my wheels/tires combo for $150.

I got a PM the other day with a guy offering me 3 amps for the rims/tires.

#1-RF Punch 500aII

#2-RF Punch 150aII

#3-MTX RT 4240

I only know the basics of car audio, and all three of these amps are unfamiliar to me. Does anyone have any experience with these amps? Are they better to run with a subwoofer or for my 4 speakers? Maybe I can use one for my sub, one for my speakers, and sell the last amp? Yes Im a stupid noob, so help is much appreciated. Thanks in advance.

Both are well respected companys.

Heres some specs-

MTX RT4240 Amplifier

--------------------------------------------------------------------------------

RMS Power measured at 12.5 Volts DC:

45 Watts x 4 into a 4 Ohm load with less than .5% THD

60 Watts x 4 into a 2 Ohm load with less than 1% THD

120 Watts x 2 bridged into a 4 Ohm load with less than 1% THD

Dynamic Power (IHF-202 Standard) measured at 14.4 Volts DC:

55 Watts x 4 into a 4 Ohm load

100 Watts x 4 into a 2 Ohm load

200 Watts x 2 bridged into a 4 Ohm load

RF punch 150

-------------------------------------------------------------------------------

Amplifier Type: 2-channel

RMS Power @ 4 Ohms: 75W x 2

THD at 4-Ohm RMS Power: 0.08%

Bridged RMS Power @ 4 Ohms: 180W x 1

FR punch 500

------------------------------------------------------------------------------

So the punch 500 would be a solid subwoofer amp?

The others are better for speakers and components, etc..?

Ya, pretty much.

The 500a2 is only 4ohm stable bridged so if you go and buy a couple subs be sure they can be wired for a 4ohm load.

How would it handle something like 1 10" HX2 or Type R...?

Better question-

How well will would a 10" HX2 or Type R handle 500watts RMS.

type r would fit if you could find a dual 2 ohm
