RF T1500BD or Stetsom 1K5

One of these will be my next amp. The T1500 may or may not be the CP version. I will decide that if I decide to go with the RF amp.

Will be powering two DC lvl3 15's.

i say go with the stetsom amp!

also how is your cars electrical? enough to handle the amp?

Both are good amps. I say go with stetsom just because there are less people running them than fosgate

Well my last setup was a US Amps AX-3200 and the only electrical upgrades were a Kinetik 1400 up front and a 2000 in the back. It ran fine at 2 ohms. So with this setup I am planning on going simple and light so I squeezed the biggest I could fit under the hood so I went with a XS Power D3400 which is supposed to be good for up to 2500 watts so we will see.

Oh yeah, which one would be the most efficient at 1ohm?

stetsom is said to be as high as 90% efficiency, but the BD technology is apparently supposed to be very efficient also.

I would go with the stetsom, they have a small footprint and also the thing about fosgate amps, if the thermal protect breaks you're in trouble.

Stetsom for the variable subsonic filter.

I have 3 R/F T1500-1bd's,

They are nice amps. Well built. Great power ratings.

Here's my two cents if I was going to throw down some money.......

R/F's slim T1500-1 needs an external fuse.

No built in cooling fan, which is needed on these if ran at one ohm....(found out the hard way)

Are capable of producing well over the 1500rms wattage listed at 14.4 volts.

Stetsom V series has a small amp as well,

Built in cooling fan (as I can tell on most models)

Also needs external fuse.

Priced cheaper than the R/F models. (as far as MSRP is concerned)

The V series is rated around about or way higher rms wattege than the R/F models I've ever seen...

If it were my money,

I go with the Stetsom V series....

here are some real close number to what the 1k5h gives you on efficiency (and thermal protection breaking, this is not easy to happen )

1K5 – 1 OHM

1 OHM – 83%

2 OHMS – 94%

4 OHMS – 96%

1K5 – 2 OHMS

2 OHMS – 84%

4 OHMS - 91%

8 OHMS - 94%

Right on, that's some good info.
