I have an American pro vs3507 and 2 poineer premier champion pros 400 w rms is this amp enough or should i break out the power acoustic reaper 6000w both are mono

SOURCE: audiotek amp

RMS(power) = peak(power) * .707

find the peak power of your amp and use the above formula

It will have enough power to do so.

SOURCE: Connecting a subwoofer to a mono amp that has 2 sets of terminals

ok this gets confusing sometimes. Ok first look to see what ohm your subs are. If you have a dual 4 ohm sub When you run that on sub + to + and - to - then that will make that sub 2 ohm. its different on ohm if the sub is say a 8 ohm then putting the wires that way will bring that sub to 4 ohm. Now lets say you have 2 subs that are dual 4 ohm and wire both of them + to + and - to - and go bridge the amp which would be both wires from sub both + together and both - wired bridge on the amp will make it a 1 ohm to the amp. Please post what ohm your subs are and i can tell you alittle more about it

SOURCE: adjusting wattage on kenwood kac 9103 class D mono amp

That amplifier is 900W x 1 @ 2ohms.
If your subs are 4ohm SVC wired Parallel, resulting in a 2 ohm load, each sub will only see 1/2 of the rated power. (450W ea.)
Your gain (sensitivity) setting should be between 75% and 85% to max. You will be fine.

SOURCE: Rockford fosgate 800 a2 amp power?

Hello desperate2le,

Watts delivered is a function of the voltage times the current. If the amp was 100 percent efficient, it would need 33 amps at 12V for 400 watts. At 14.4V, it would only need 28 amps. Of course, amplifiers are NOT 100 percent efficient, only about 50-60 percent in many cases, but somewhat higher for monoblocks, maybe 80-90 percent. So you're looking at a fuse in the 60-80A range. In the absense of a specific fuse size from the manufacturer, I'd start the primary fuse at a 60A and if the amp blows it on power up/immediately/frequently, move up to an 80A.

All of the Rockford-Fosgate 2-channel bridgeables I've ever seen show using the left positive (+) and the right negative (-) for bridging. But if it's not shown right on the amp, I'd call or email RF for the correct connection. The new amps do show it.

Hope this helps.

SOURCE: got a 12"kicker L74ohm sub and sony xm-D9001GTR mono amp

Hello juan_penaloz,

The Kicker L7 has an RMS power range of from 50-750 watts and a maximum power handling capability of 1,500 watts so your Sony amp will power it OK. A more powerful monoblock like the Alpine MRP-M1000 or the Kicker 08ZX750.1 would provide even more power and could operate safely at 2ohms.

You have the voice coils wired properly for the Sony amp. It's OK to have the sub impedance higher, but you definitely do not want it lower than the 4ohms the amp is rated at in bridged mode.

Hope this helps.
