Monoblock amp with DVC subs

Hi I have the most retardedly confusing question that's ever been posed so bare with me here. I have a performance technique ICMB-DIGITAL and I just blew out both my subs. I have a 99 lexus gs 300 which had a stock sub. I want to run a KICKER 07C104 free air in the place of the stock sub, but then I want to try and run a KICKER CVX12 in a box in the trunk just to add some thunder. Is this even possible? My next question is why does a monoblock amp have 2 sets of terminals? Is it internally bridged or something?

Is the amp 2 ohm stable, and are the speakers 4 ohms apiece? ohmage is indicated by a number such as 4 followed by the greek letter "omega"

if the amp is 2 ohm stable, and both speakers are 4 ohms apiece, then yes you can hook up both, one to each terminal set

this amp is 1 ohm stable and a monoblock which means there is only one channel in the amp so if you run both subs parallel at 2 ohms and parallel them together you will be at 1 ohm which this amp will handle excellently. i know this because i have it and have been running it at 1 ohm for the past 2 years with no problems.

How do i wire 2 fosgate punch 10" subs to this boss iq 680.2 amp? the subs are rfd2210 hx4 and theres two subs in a separated seald box. i need to know how to phase all the vcs together


Your subs are 4 ohm dvc so lower the impedance more power from your amp. I will include a link that will show you how to wire your subs for maximum performance. I would explain it but seeing the drawing will make more sense....

How many svc subs at 4ohm does it take to get this amp to 1ohm stable and can you reccomend a good sub combo for this amp whether it be dvc or svc


It depends if your sub is 4ohm svc, or 2ohm svc. 4ohm would take 4 subs wired in parallel, 2ohm would take 2 subs wired in parallel. But for a amp that big, subs that'll handle it are definitely gonna be dvc. I'd recommend 2 Orion 4ohm dvc hcca's. They come in either 15in or 12in. the 15s are louder if you have the space for them. As far as wiring goes, wire the voice coils on the subs in parallel to 2ohm per sub, then wire the 2 subs in parallel to 1ohm. Goodluck and congrats on the equipment, Orion is about as good as you can go for subs and amps. just be ready to lay down some dynamat cuz this system'll bloww your vehicle apart! good luck...

I just need to know the best way to hook my amp and subs together. i like a lot of bass. i just bought the subs and yhey dont really sound any diffrent. should i get a new amp.


Hello hembreegerry,

If you like a lot of bass, you definitely need to consider another amp. The SP2X-300 is only rated at 170 watts RMS into 4 ohms mono. That would barely be enough to power one small sub. You do not specify what brand and model your subs are, their impedance, or their power handling capacity. But for any subs, your best power solution is to add together the individual RMS power handling capacity and select a monoblock amp that provides close to the maximum at the impedance they will be wired to present. For example, if your subs are 4 ohms and have a maximum RMS of 250 watts, you would want an amp that outputs abour 500 watts into 2 ohms (2 4 ohm subs wired in parallel = 2 ohm load). An ideal amp in that example would be the Alpine MRP-M500 which outputs 500 watts RMS into 2 ohms.

Hope this helps.

Amps on woofers are fine just won't hit


your probably making your amp run to low ohms if its a 2 channel amp bridged to one channel you can probably only run it at four ohms

Also seeing as your subs are 2ohm dvc you can't wire them individually to 2ohm and use each channel separately. So i'd recommend buying a 2ohm stable monoblock or running it at four ohms. a 1400 watt amp'll still pound at 4ohms and it'll extend your amp's life span

Got jl300/2 amp confused which subwoofer sounds good


Hello drsubhakar26,

JL W6's will perform well with from 150-600 watts RMS. W7's with from 150-500 watts. Less expensive Alpine Type R's work OK with from 200-500 watts RMS. Either of the brands will sound good. None of them will perform to their full potential with 300 watts RMS. Powering any sub with a 2-channel amp is a compromise. A monoblock is more efficient.

Hope this helps.

I HAVE A JL AUDIO MONOBLOCK AMP 250


there could b allot of factors involving this problem first could and most important is to make sure theres no loose connections in your wiring and find out how ur subs are wired in. are they SVC or DVC (single and duel voice coils) also what are theyre impedences if SVC could be 2, 4, or 8 also the same as DVC but jus 2 sets of terminals. find out first then the reason i ask is cause allot of half way manufactures are installing a device u could say that will cause amps to automatically cut off when the load on the amp reaches its lowest impedence load so when ur subs are moving in and out that load varies with how far the sub is extending out jus cause a sub say its a 4 ohm SVC doesnt mean that when its pounding away the load may actually be 3 ohm when fully extended. find out these variables first and then reply and ill let u know what to do properly.

KAC-9104D output terminals


ok i have the same amp and 1 2ohm dvc sub and was woundering the same thing but from futher research and askin sum xsperts. What i found out is that it is only one channel and even tho there are 2 (+) and 2(-) they actually connect inside the amp makein it one . so if u wanted to wire sumthing parralel u wouldnt have to hook wires from one coil to the other on the speaker , u can just hook it up to the amp. so basically both +'s and negatives on the amp are actually one within it so all the power if you only use one set of them and if u wanna add more subs its just easier to add to the amp by using the xtras .

The amp says it's 1 ohm stable, so assuming the DVCs are dual 4 ohm, you should be able to connect all "+"'s together and all "-"s together, like the picture below:

As for the amp shutting off for a few seconds, it sounds like it's either:
A) Not getting enough power at high volume.
OR
B) Overheating.

The cap on the +12V to the amp should help, but putting a meter on the +12V might tell you whether it's dropping too low (<11V).

When you first turn the volume up, how long does it work fine before shutting off? Is it with the vehicle running or not?
