Im trying to find RMS specs for PERFORMANCE TEKNIQUE CBM-5712 SUB

Personally, I would not put more than 500 RMS total to that sub. 300-400 RMS is more like it.

The 500W RMS total wattage is for both coils combined. If you want to get REALLY specific, all of the industry-specific specifications are as follows.

12" Dual 4 Ohm Peformance Subwoofer

Power Handling:

• Peak: 1000 watts
• RMS: 500 watts

Impedance: Dual 4 ohm

Reinforced aluminum curvilinear cone woofer

Oversized butyl rubber surround

5 spoke Die-cast aluminum basket

2" Flat ultra excursion spider

Industrial Chromed Hex bolt retained T-Yoke

DC resistance (Re): 3.2 ohms each coil

Frequency range: 20 Hz-1.1 kHz

Fs:30 Hz

QTS:.526

QES:.614

QMS:7.698

VAS:56L

SD:.0491M

SPL: 89.58 dB 1W/1m

Xmax:16mm

Mounting Depth: 160 MM

Mounting Hole Dia.:282 MM

You can't go wrong with Rockford, in my opinion. Everything they make is well built and high quality. I personally have two Rockford p500-1bd amps hooked up to four 12 inch subs in my car and those amps make those subs slam. I have them wired down to 1 ohm and the specs say that they should be pushing 500 rms a piece at 1 ohm so that p700-1bd amp really packs a punch. Depending on what you're hooking up to that amp I would defenitely recommend it to you. - Ryan in Alaska

Sure. Specs are listed below. I think it's designed for regular 2-channel input, isn't it?



Front Channels: 100 W RMS x 2 @ 1.5 ohm-4 ohm (11V-14.5V)

Subwoofer Channel: 250 W RMS @ 1.5 ohm-4 ohm (11V-14.5V)

THD at Rated Power: <0.03% @ 4 ohm (F&R), <0.05% @ 4 ohm (Sub)

S/N Ratio (F&R): >108.5 dB below rated power S/N Ratio (Sub): >95 dB below rated power

Frequency Response (front and rear): 5 Hz-30 KHz (+0, -1dB)

Frequency Response (sub channel): 5 Hz-500 Hz (+0, -1dB)

Damping Factor (front and rear): >200 @ 4 ohm/50 Hz

Damping Factor (sub channel): >500 @ 4 ohm/50 Hz

Input Range: switchable from 200mV-2V RMS to 800mV-8V RMS

Differential-Balanced Input Topology: (3 pairs of inputs)

Dimensions: 19.7"L x 9.25"W x 2.36"H

is the amp 2 ohm stable? does the amp have enough watts to support the rms of the sub

yor subs have dual 6 ohm voice coils from the sound of it-your amp is rated at 650 watts rms at a 1ohm load. The best you can do with the equipment you have is to wire ALL the coils of your subs in parallel and that will give you a 1.5 ohm load for the amp.It should knock the hell outta them with 300 watts on each sub - good luck

if you get the 4ohm you can wire it to run a 2ohm an the kenwood amp will push 900 watts at 2ohms.they say it can push up to 1800 watts,that would be at 1ohm.that kenwood runs 500 at 4ohms an 900 at 2ohm.if you need help wiring the sub or anything else let me know bertman285@hotmail,com Max Power Output 1800W Power Output 4 Ohm [14.4V] 500W x 1 [20-200Hz, 0.5%THD] 2 Ohm [14.4V] 900W x 1 [100Hz, 1.1%THD] Bridged[4 Ohm] -

No, with 1700watts at 1 ohm the max current is 41 amperes, with 1500 at 0.67 the currents is almost 48 ampreres, you will be overdriving the amp at signal peaks.

you will get more power at lower ohms, the lower the ohms the less resistance it will have against the amplifier

heres a small definition if it helps

The ohm is defined as the electric resistance between two points of a conductor when a constant potential difference of 1 volt, applied to these points, produces in the conductor a current of 1 ampere, the conductor not being the seat of any electromotive force.[

Whats yhe Rms on this sub? Which is better compared with the 5712 modle?
