i just get this amp,....at their spec above,do i need e-crossover to punch 2pieces sub??....or just that amp only (no need pre-amp&e-crossover)???...
another thing...it's good to punch 2 sub on bridge mono mode??...
anyone have use it before?..need info...
thanks!.

You wont be needing another crossover(already in-built) nor pre amp...but what size/brand/model subs are you planing to use the amp with?

 

[deadman]

its rated 160rms and its a 2 channel..

 

[W9909]

i got 2pieces 10" rockford punch already(RFZ1410 or RFP1410 mybe.),not so sure...mybe 50-200rms....
it's worth if i'm going bridge mono??...are bridge mono like parrallel the sub?
another thing...it's produce good bass went go for tri-way output??2 for front comp,1 for that bridge mono sub....

thanks master D!..

 

[deadman]

just bridge the amp up...get one more amp for your mid..this amp is more suitable for sub

 

[W9909]

ok....how's about that sub??if i parrallel it,seems like not balance,the nearst cabel the louder....this happen went im using normal amp(30rms nonbridge),that im not assemble 160.2 yet...it's true wiring??or that amp not enough power to punch??

thanks dude!

 

[ericlo]

i'm sure your amp will nvr whack 2 subs with great punch. its under rated man......

160w RMS briged means each subs will have 80w rms. what subs are you using? what do you mean not balance, is it out of phase. is it the same model of subs or dufferent brand or model?

btw what is "true wiring"?

30w rms non bridged? i though its a 80w x 2. if that do then the amp is:

max power 80w X 2 @ 2 ohm
40w rms x 2 @ 2 ohm
160w max x 1 bridged @ 4 ohm
and 80w rms x 1 bridged @ 4 ohm.

am i right?

 

[W9909]

i didnt assemble my RF amp yet...just test my sub with my old amp rated 60rms(bridge),when i plugin input ,the sub near input is more louder than one,the sub on parallel mode...it's coz my old amp not enough power ??just wonder to know...that for my old amp...it's bcoz of wiring or that old amp?

the RF sub around 50-200rms both are same model...i think so....pic above...
the RF amp spec;
40w rms x 2 @ 4 ohm
80w rms x 2 @ 2 ohm
160w max x 1 bridged mono @ 4 ohm

btw, how to know if out of phase??

 

[appleyard]

out of phase means that both subs did not move linear. try and see when both subs are playing. are they moving linear? even when your amp has not enough power, your subs will still have the same power.
try and check your wiring and cables? i doubt its your cables or the subs itself.
