Just put a ten inch 600w rms sub in my car, the amp I'm using is 600w rms. Previously I had a 12 inch 300w sub powered by a 250w amp. The new sub output or level is less than half of the 300w sub, whats wrong? Thanks.

Yes...just turn down amp level then crank radio as loud as you will listen to it. Then slowly raise gain back on amp until sub is laboring a bit then turn it back down a bit.

Hi there,

This really depends if your 10" subs are 4 ohms each or 2 ohm - for this exercise, I'm presuming they are 4 ohm each.

You already know your amp can deliver 600W RMS (@ 2ohm), so you need to be careful you do not exceed the maximum RMS input power of your subs.

Normally you would wire subs in "parallel", which would reduce the circuit load to 2ohms - however, the 600W RMS power may be too high for your subs to handle.

In this case, it may be safer to wire your subs in "series" - this will increase the circuit load to 8ohms, which will effectively decrease the amps RMS power output.


Cheers,

match your total rms output at the resistance you will be running the amp at to the subs.
example:
if your amp puts out 300w RMS@ 4ohms, then it will produce 600w RMS@ 2ohms. half the resistance, double the power.
So now that you know your available power, you should get speakers that will be used to the fullest at that given resistance.
example:
If you have two 4 ohm subs that have a power handling of 300 watts, Then you can wire them in parallel ( + to + and - to -) to get a 2 ohm load (which will be 300w per sub with the above amp) or in series (+ to - to + to -) to get an 8 ohm load. (300w amp @ 4ohms = 150w amp @8ohms = 75 per sub).

Keep in mind: choose the speakers to fit the amp, not the amp to fit the speakers. If the amp has more power than the speakers can handle, you will blow them. and ALWAYS USE RMS WATTAGES.

depends on what the RMS is for the subs because although the subs are 1200 watts, there is a minumim standard you have to follow. If you don't atleast run the lowest wattage thru them, then you will most definately damage the speakers....you should also be aware of the fact that your "600w Pioneer-4 channel amp doesn't even push a true 600 watts... Your best bet is to upgrade ur amp, or add an additional amp to your set-up. And you really need to pay close att to over or under running your power to your stereo system because you'll burn out ur altenator rather quickly. Use proper wattage , and you should also look into getting a power-cell which lessens the chances of destroying your altenator and helps to ensure that your stereo system sounds to its full potential.....

Only way to drop the impedance is to putting subs in parallel or to use 2 ohm subs. I will add you a link to wiring subs:

No, thats what you don't what to do. Even if you have 2 matching amps you don't do that. Every amp puts out different, and for 2 subs, you want to play at the the same time. If your only running 2 10's, I personal would just run the alpine (it's a mono amp made especially for subs) thats plenty for what you have. make sure you bridge them to get the full response. And your other amp i would use for your highs or mids, but run it @ stereo , which is 300 w @ 4 ohms. (Note: 600w @ 2ohms would be bridged and would play in Mono)

Building Competition stereo's is a big hobby of mine.

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.

This amp will not give you 1000 watts of real power. From the specs I've found, it can produce 55w RMS x 4. Bridged, that would be 110w RMS x 2. The most you could get into a dual voice coil woofer would be ~220w RMS.

For each sub, tie the DVCs in parallel ("+"s together, then "-"s together). This will make the subs look like 2 ohms to the amp. Then, put one sub on each channel of the amp. That will put about 280W rms onto each sub, the max for the amp.

While I don't have any first-hand experience with either Bazooka amps or Memphis subs, this review pretty much says what I initial thoughts were. The amp will do the job without much fuss, so it mainly depends on whether you can get it for a good price.
BUT........
There could be a issue with your sub. According to Memphis, your sub (assuming it's the single voice coil version) is only good for about 250W RMS (let's ignore peak power for now). The ELA500.1, on the other hand, puts out 375W RMS at 4 ohms. You could very easily overpower your sub with that amp.
