Re: punch he 4 ohm 200 rms 400 peak

The winding on the voice coil are coated with a varnish to keep the from shorting to each other. If the sub is drivin to hard or the voice coil is not vented properly. the voice coil windings will get so hot the varnish will melt or someting get sticky. When you quit playing the sub, say overnight the varnish cools and acts like a glue and will cause the voice coil to stick to the basket of the speaker. Repair just would not be worth the money or the time. Plus when a speaker reaches thid stage. It could eaisily fall to short and burn out your amplifier.

I'm new to the Car Audio seen.I just bought four 6x9's.Now I need a good Amp to push all four of them.Here's what I have.Sony XS-R6945 4 Way 6x9" 800 watt Full Range Car Stereo Speakers Power...

Look for a 4-channel amp that pushes 50 watts RMS @ 4 ohm.
Make sure the amp is CEA-2006 compliant.
Ignore peak or max watts as these are arbitrary numbers.

What kind of amp can adequately power P112 S8 subs

you shouldnt run it at 8 ohm it shows what ohms it can handle . to run it at 1 ohm you would need 2 subs to do this. and no i wouldnt run an 8 ohm sub on the amp.

Which will hit harded 2 ohm or 4 ohm

In general, the 2 ohm speaker will be louder than the 4 ohm with most amplifiers. For example with this amp being sold at Best Buy you have 400 watts rms at 4 ohms or 600 watt rms at 2 ohms. However, being the same model sub they should 'hit' the same.

Hope this helps

What size amp needed with a sony explod player?

this bandpass enclosure is rated peak power at 1200 watts . what this means is that each subwoofer in the is peaked at 600watts to make 1200 watts . what your looking for is to power up the subs with rms continuous wattage . you need an amp that will put out 400 to 500 rms a channel to run this sub enclosure at 800 to 1000 watts rms to keep the speaker from blowing

audiopipe apf1801
71671968.jpg this amp will give you 1 channel @ 4 ohm x1 350 watts 1 channel @ 2 ohm x1 900 wats 1 channel @ 1 ohm x1 1800 watts you would have extra power for better subs with more power later but you get 900 watts which when connected right would mean 450 watts per sub be perfect for you . i sell this for $320.99 in my store can shipp any where in usa to contact me

Finding the best amplifier

Hello sharky75,

That 1600 watt peak power figure for your subwoofer can't tell you what amp you need. You need to know the maximum RMS power the sub can handle. And you need to know the impedance (ohms) of the voice coil(s). JBL GT5 series subs have an RMS rating of 275 watts. The GTO series handles 300 watts. The Power series handles 400 watts. The GTi series handles 700 watts. Some are single voice coil, so the impedance is fixed. Others are dual voice coil allowing you to wire them for different impedance loads.

For maximum performance your amp should be able to provide at or near the same number of watts RMS into the lowest impedance at which the sub can be configured. For example, if your sub is the Power Series Model number P1224, it has dual 4ohm voice coils and can be wired to present either a 2ohm load (parallel) or an 8ohm load (series). You want to wire the voice coils in parallel for the 2ohm load and select an amp that outputs up to 400 watts RMS into 2ohms. The Orion Cobalt CO8001 is just such an amp. If you have one of the GTi Series subs, a better amp would be the JVC Arsenal KS-AR75 which outputs 700 watts into 2ohms.

Hope this helps.

Hello king3132,

Three 4 ohm subs can be wired parallel for a 1.34 ohm final load or series for a 12 ohm load. If you have the channels of the amp bridged, I hope that the subs are connected in series because the Sony XM-2200GTX is NOT rated for or stable at 1.34 ohms. It's only stable down to 4 ohms.

You definitely will not get the maximum potential of the subs from that amp. They can handle 400 watts RMS each (total 1,200 watts) and the amp is only capable of 500 watts RMS into 4 ohms (less at higher impedance), so each sub could only be getting a maximum of 166.6 watts RMS.

Hope this helps.

Mtx audio 4252 amplifier

Hello freshman_fox,

63 watts X 2 @ 4-ohms.
125 watts X 2 @ 2-ohms
250 watts X 1 @ 4-ohms bridged

Since no power rating is given @ 2-ohms in bridged mode, it means that the amp is only stable to 4-ohms.

The manual does not specify a peak power, but since RMS is about 70.7 of peak, that makes it 353.5 watts.

You can download the manual from here. Hope this helps.

Rockford Punch HE2 wiring question.

if your sub will handle it, bridging it will give you more power. The best thing to do is to find out how much power the amp puts out ( RMS ) and if it is in your power handling range bridge it. It sounds better and gives you a harder punch because of more power.

Knocking noise with my kicker compvr 15"

comp VR 15s are rated @ 500W RMS 1000Peak.
The lanzar vibe amplifier is 2 x 600W RMS at 4 OHMS 2 x 1200W MAX at 4 OHMS 1 x 2400W MAX at 4 OHMS Bridged 2 x 1000W at 2 OHMS RMS.
Your subs are single 4 ohm subs.
If your subs are wired stereo, they both are seeing 600W. (more than the rated RMS)
Chances are, you have them wired parallel to a 2 ohm mono load - of which that amplifier is not rated. In theory, it will produce about 2000W @ 2 ohm mono for a short period of time.
Your amplifier is too powerful for your subs. Turn down the gain setting to 3/4 or purchase better subs. Also be sur the subs are inthe proper enclosure. It sounds as if they are excurting past their linear x-max and colliding with the rear bump plate. This will cause damage down the road if left as is.
