    No, the 80.1 is only 1000rms actual, and 2 cvrs will for sure hold 1000rms a set.. all day. MA audio subs are cheap junk in the presence of kicker.. if u wnat cheap AND good, try hifonics.. even the hfi amps are beasts for the $

I have a kicker sx650 powering two kicker cvr 102 at 2ohms but i havve no clue on where to set the settings at and i know this amp should make these subs pound. i need to know exactly what to put each...


How I tune:
turn amp all way down or disconnect rcas for now, turn up stereo to a song with some bass you listen to and crank it as loud as you would (not max about 3/4, use this to tune inside speakers (don't have bass maxed/distortion...)). Now dial in amp: turn up a bit probably to 1/4 or so then tune frequency I'd usually say around 100hz, then adjust gain again to where it sounds good...be easy on them for awhile to let them break in (don't blast them all day!). Usually bass boost is only 1 frequency with a curve (40hz or something)...so I try to not use it much....

I have a comp s 12 2ohm kicker and a comp vr 12 dual 2ohm kicker how do i wire these to stay at 2ohms to the amp


you can wire them to be at 2ohm load you need two of the same speaker. its is very bad on the amp to run like that and you will not get a good bass sound because one will over power the other sound wise

1 Answer

Two questions. 1) can my amplifier over-power this sub; kicker L7 15 inch dual voice coil 1,000 watts RMS wired for 2 ohms? 2) is my amp too small for this sub-woofer? thank you for your time.


No, your not over powering your L7, your underpowering your subwoofer.
Your Kenwood is
500W x 1 at 4ohms [20-200kHz 0.5% THD]
900W x 1 at 2ohms [100Hz 1.1% THD]
Your L7 is:
Max Rec Amplifier Power (WATTS PEAK/RMS)* 2000/1000But its ok for your subwoofer, alteast your not giving it to much stress. But personaly, get another mono amplifier that would match your subwoofers rating.

Overheating amp problem...easially fixed, i think....


depends on the sub rating.

if subs are 2 ohm rated you can ONLY get 1 or 4 ohms..
2x2=4ohm series
2/2=1ohm parallel

if subs are 4 ohm rated wire in parallel
4/2=2ohm

look it up google for diagram if you need one.

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.

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.

What amp will push 2 kicker 15inch cvr's


Hello herb31,

Kicker lists the RMS power handling range of the CVR's from 100-500 watts, with a peak power capability of 1000 watts. There are lots of monoblock amps within that range. It just depends on how loud you want them and how much you want to spend.

In the low range, an amp like the Alpine MRP-M500 will deliver 250 watts to each sub at 2 ohms. And it only costs $179. Currently, the MRP-M500 is out of stock at Crutchfield. I just bought the last one. So my 2nd recommendation would be the Sony XM-1S, which has the same power rating and according to Crutchfield is no slouch either. It's also $179. I really like the Sony, too. It has a small footprint that makes it easy to find a convenient mounting location. Both the Sony and the Alpine are CEA-2006 compliant, so you can be sure that the manufacturer provided specifications are not overrated. Assuming that your vehicle electrical system can deliver the current, both the Sony and the Alpine will deliver an honest 250 watts RMS to each of your Kickers. And 250 watts will make them kick pretty darned good.

In the medium power range, consider either the JL Audio G Series G1700 which delivers 700 watts into 2 ohms. It costs $419 at Crutchfield. Or perhaps the Kicker 08ZX750 with 750 watts at a cost of $399.

To push the CVR's really hard, close to their 500 watt RMS maximum power range, look for an amp that delivers 1000 watts. In this range, you will definitely some heavy-duty wiring, electrical system upgrades, perhaps a 2 farad capacitor, and be ready to spend at least $600 on the amp. Your best combination of power and price would be another Alpine, the PDX-1.1000M, at $799. If you buy one from Crutchfield, they will throw in a 4-gauge amp wiring kit. And if you use a "friend referral code", such as mine, which is p7sdj-hrx8q-9800g, and your order is at least $200, you'll get another $20 discount. And I get a $20 credit toward a future order.

Hope this helps. If it does, please rate as "FixYa".

What is best amp to run 2 12 inch cvr's


12In Kicker CVRs
are Dual Voice Coil, and You can run each voice coil around 200 Watts RMS

So each sub will have a 400 Watt RMS and 800 Watts peak.

Now since you have 2, Your total will be 800 Watts RMS and 1600 Watts Peak.

I would get really any amp that sits at around 800-1000 Watts RMS.

These are kicker but they are low end so i wouldnt push them to the extreme.

1000-1200 Watts RMS Max and but keep the Gain down on the amp. They will hit no doubt but i wouldnt push these subs or you will be disapointed in the long run.

I would get a Fosgate or MTX amp.

You can get any amp really but find something right around 1000 Watts RMS and it will push those well.

You can go mono block or a 2 channel, just depends on how you want to wire them.

Be careful though. If your running them bridged right now with your mono block, do not run them parallel bridged on a 1000w RMS Amp, you will blow them so fast lol

(RMS = Root Mean Square. Or in other words is the continuous wattage being sent from the amplifier to the subwoffers)

Trying to figure out what kind of amp i got amercian pro vs-3507?


The VS3507 Is a class D monoblock.
Your optimum wiring for this amplifier is a 2 Ohm load - so it produces its full potential power of 350W RMS.

To Achieve a 2 ohm load, the most common load is one of the following...
(1) Dual 4 Ohm Voicecoil Subwoofer Wired in Parallel.
(2) 4 Ohm Voicecoil Subwoofers wired in Parallel.
(1) Quad 2 Ohm Voicecoil Subwoofer wired in Parallel/Series.
(1) Single 2 Ohm voicecoil subwoofer.
