You should get the dual 4 ohm version of subs and wire them both in parrallel and series for a 4 ohm load to that amp, Bridge the amp and your subs should be seeing about 960 watts true rms.

Why do i need to open my gain up to 3/4 to full turn inoder to achieve a loud bass?Im using punch 2400 amp and 2 12" kicker.


the amp may not be powerful or your setting on the cd player is not right try adjusting the cd player. turning the gain all the way up will damage your subs even go above halfway

I see someone asking about this amp running a single 15" sub, how about running 2 10" subs?


Do you know how many ohm's the two 10" subwoofers are ? That is important as there are many ways to wire multiple subs. If you dont know then post what make and model the subs are.

Post back and I will try to be of further assistance.

Thank you for choosing Fixya!

Need amp for 2 15 l7 4 0hm


Hello jasonjohnson,

There would be more amp choices if those L7's had the 2ohm voice coils, allowing you to series the coils and then run the subs parallel to the amp for a 2ohm load. As it is, you'll probably have to run them as either 1ohm and have limited amp choices, or as 4ohm and settle for a little less power.

An absolutely excellent amp to use at 4ohm would be the Alpine MRP-M1000. At Crutchfield this one is on sale for $347. For more power, and an amp stable to 1ohm, I would recommend the Rockford-Fosgate Punch 1000-1bd, a "factory refurbished" model is available at Crutchfield for $349.99. It's $700 new.

Both of these amps have adequate power for 2 L7's, but the RF will definitely be the better power choice. Both are also well respected names in mobile audio and the prices are reasonable.

If you have deeper pockets and want to push the subs really hard, a Rockford-Fosgate Punch 1500-1bd will put a full 750 watts RMS to each sub.

Hope this helps.

Amp or something cutting out.


Power caps store power from the battery and they feed constant power to the amp so you dont get no drainage! this could be one reason..

have you bridged both subs and wat gauge wire are you using.

these amps can only handle one bridged sub at 4ohms and this amp is recommended that u use 8gauge or higher. if your running to subs i normally reccomend using 4 gauge power wire as you get more rms power feed to the amp

you can get a power cap or anyother accersory cheap online at my suppliers.. caraudiosecurity << click to enter >> hope this helps and please rate me :)

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.

Multi amp hook-up


honestly i dont think those to amps will push cvxs no matter how you wire them up.
the rms on the 200 should be used to push a door speaker.
the 800watt should deff just be hooked to 1 cvx but still wont max it out.

Is this ok?


yes 2ohm should be fine for that amp no problem

But dont bridge it any lower than 2 ohms.

Rockford Fosgate 800a2 To 2 SVC 2ohm subs


Ok.. Bridge the two sub into 4ohm than bridge to amp.


So. this how it goes.

sub1 + -
to      | |
sub2 - +
=      4ohm
       

           From Sub
                Two
            -          +  
            |           |
amp (L) - + (R)- +


This will use the full potiental of RF 800a2 amp. I believe it like 1153 watts max out.

Amp overheating and adjusting gain and frequency


Overheating in amplifiers is often caused by a speaker load of too low impedance. If your L7 is a dual 4-ohm voice coil, and if you're using the amplifier in bridged mode, that may be causing your problem. Dual 4-ohm subs, with the voice coils wired in parallel, present a 2-ohm load to the amp. Your amp is capable of running a 2 ohm load in 2-channel mode, but not bridged mode. The best fix with your equipment would be to re-wire the sub's voice coils in series, resulting in an 8-ohm load. The amplifier's power output will drop sharply, but you won't have problems with overheating in that configuration. There's a good chance that you'll still be able to get all the volume you want, even with an 8-ohm setup; otherwise you'll probably want to switch to a mono amp designed for a 2-ohm load.
