Looking for a 3500w amp, budget 600.

Taramp's HD3000, HD-4000 and HD-5000.

Which one you want for under $600?

Tell me what ohm load you are wiring to and i'll tell you what to expect.

These amplifiers are the best price to performance on the market with efficiency capabilities that far exceed anything else on the market.

I dont know much about the brazilan amps, but from what i have seen on other forums there seems to be mixed reviews.

people didn't expect much amperage draws comming from such small footprint amps and start blowing it from depriving it of power. Either that or they run voltages waay to high past 16v. There's a guy near me running the hd4000 with two fi BL 12s for a little over a year with no problems.

No. People are\have been blowing them up because their required operating specifications is not the same as your typical chinese\korean amplifier.

The reason for this is quite simply, people abuse their amplifiers so companies have them overbuilt to withstand 0.187-0.5ohm DCR loads for daily.

If people are running the voltages past 16v, the protection will kick in.

I know a LOT about Taramp's.

I can tell you this now-

The HD Series-

Operating Power Supply Range-

10.5v-15.9v

Operating Range under Maximum Signal Gain Output(voltage restriction based)- 10.5-14.4v)

Operating Range for MOSFET function- 1.4ohm+ Resistive (2.8ohm+ Resistive for 2ohm models)

So what does this all mean?

MOSFET function- Do not wire(for 1 ohm models) transducer load below 1ohm Nominal. Not DCR, but Nominal.

Maximum Signal Gain Output- when the amplitude of any signal during playback reaches maximum level for output, the DC input voltage needs not be greater than 14.4v during the load(no higher than 14.4v after voltage drop.)

While having the DC voltage above this During Maximum Signal Gain is not going to kill it, it can\will deteriorate the components slowly over time.

The amplifier can safely run up to 15.9v with no problem as long as the amplifier is not fully loaded down.

So, an example-

User uses an HD4000. He has a 200A alternator.

This is not enough to support the amp by itself so this is good IF the alternator is regulated above 14.4v After it is hot!

However, due to ways of wiring, you can easily wire a 0.1-0.7v drop in the rear even if your alternator is strong enough to withstand 15.0v solid under load..

This is easy..

So, anyways, you subject a load onto the amp. IF the load is at maximum potential, then the DC voltage needs to be at or below 14.4v at the amp which is very easy to do.

that's it. The reason for this is the switching voltage inside need not be above a certain value during playback or slow, progressive failure to the transistors can occur.

Wiring below 1ohm nominal(DCR values typically lower than 0.65ohms) will heat the FETs up a lot quicker than normal and cause failure.

Maintaining a load above 1.40ohms at all time will guarantee the user will never reach the amperage limit of the FETs for long term playback.

IF you have any particular questions, feel free to ask.
