what amp would you guys recomend to power 2 Infinity Perfect 10.1 10" Subwoofers?

heres a link for the subs

http://www.infinitysystems.com/carau...er=KPE&Cat=SUB

 

Your subs are 4 ohm 350W continuous, with 2 of them you will need a 1x700W-800W RMS into 2 ohms mono block sub amp, or two 1x350W-400W RMS into 4 ohms mono block sub amps, there are a lot of them out there. 94

 

i have the perfect amp for you at a very low price... check out the link in my siggy.. the amp is listed for sale in there.. it's an mb quart amb.. check it out

Well i was thinking of buying a brand new amp.

What is the difference between 2ohms and 4ohms? could i use an amp that has 500W x 1 (2 ohm mono) such as the phoenix gold OCTANE-R 5.0:1?

or would i be better with the OCTANE-R 4.0:2?

Ohms is a measurement of resistance, in this case, simply put, 4 ohms is twice the resistance of 2 ohms.

With some, [most] amps the RMS output of the amp doubles when you half the resistance, EG: a mono amp that is 1x200W RMS into a 4 ohm load will be 1x400W RMS into a 2 ohm load, [and as mentioned, this is not the case with all amps].
In your case you have a 4 ohm 350W continuous, [RMS] sub, so if you are getting another amp find a mono block sub amp, [1 channel amp designed specifically for sub bass] that makes at least 1x350W RMS into 4 ohms, 1x400W RMS into 4 ohms would be better, IMO "overpowering" is better then "under-powering". 94

Octane series sucks IMO. PG along with everone else has slid down hill IMO.

I borrowed one of my firends Octane amps for my boat before I bought my own amp. Junk nothing but junk.

 

alright well i was thinking a JL audio 500/1 Class D Monoblock Subwoofer Amplifier but under rated power it says: 500 W RMS @ 1.5 ohm - 4 ohm (11V-14.5V)

won't this make a big difference?

i was thinking of that amp, the infinity REF611A 600 Watt Class D amp

or a Sony XM2002GTR 2-channel Car Amplifier 200W RMS x 2

which one would be recomended?

 

You can't go wrong with the JL Audio 500/1, but stay away, far away, from the Sony, it may Xplode. 94

 

I can't afford the 500/1

so what do you think about the Infinity 611a?

 

The Infinity will do the job, [1x657W into 2 ohms] 94
