Question about Profile BAJA HA700M Car Audio Amplifier

1 Answer

My sub flickers on and off in my truck!!!

Alright, so i recently installed a Profile HA700M Mono subwoofer amplifier 350 watts RMS x 1 at 2 ohms and a 2 ohm Kicker TCVT102 Sealed truck enclosure with one 10'' CompVT subwoofer. For the first couple days, everything worked fine, but now the sub will randomly shut off, and randomly come back on. I checked all my connections, and everything seems to be fine. I also have a smaller amp hooked up to power my speakers, but no problems there. I only have one set of outputs on the back of my head unit, so i spilt the rca cable along with the remote turn on cable, so i could hook up both amps. I have had no problems with my speaker amp, just the one powering the sub. Even when the subs arent putting out sound, the protect light does not come on on the amp. any help or advice would be graetly appreciated. thanks everyone. richie.

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.

What size amp needed with a sony explod player?


this bandpass enclosure is rated peak power at 1200 watts . what this means is that each subwoofer in the is peaked at 600watts to make 1200 watts . what your looking for is to power up the subs with rms continuous wattage . you need an amp that will put out 400 to 500 rms a channel to run this sub enclosure at 800 to 1000 watts rms to keep the speaker from blowing


audiopipe apf1801
71671968.jpg this amp will give you 1 channel @ 4 ohm x1 350 watts 1 channel @ 2 ohm x1 900 wats 1 channel @ 1 ohm x1 1800 watts you would have extra power for better subs with more power later but you get 900 watts which when connected right would mean 450 watts per sub be perfect for you . i sell this for $320.99 in my store can shipp any where in usa to contact me caraudioquestion@gmail.com

Hi mate very nice amp you got there here is the specs for it



Model: MA Audio HK401SX
Hard Kore Series 1800 Watt 1 Channel High Performance Class X Car Amplifier
1 x 1800W RMS @ 0.5 Ohm Mono
1 x 1200W RMS @ 1 Ohm Mono
1 x 650W RMS @ 2 Ohm Mono
1 x 500W RMS @ 4 Ohm Mono
Fully Unregulated MOSFET Power Supply
2 Ohm Stable @ Mono
1 Ohm Stable @ Mono
0.5 Ohm Stable @ Mono

if you have 2 12s just bridge them and you will have 650wrms at 2ohm running to them or one sub at 4 ohm 500w rms ps they should pump iam running 2 12s with just 360rms at 2ohm and they do the job good luck

Need help wireing sub


Is the speaker a dual voice coil speaker? If so you can wire it up a couple of diferent ways, go to rockfordfosgate.com they have a woolfer wiring wizard that can show you the different ways to wire for 8 ohm.....4 ohm.....2 ohm....and 1 ohm...I would figure out how to get the most power out of the amp in mono mode, take that ohm load from there and see if you can wire your speaker to match it.

Infinity 1211a @ 2 Ohms


Hello monkey_flea, Your subs will share the amp output. And if you are not careful, you'll end up blowing them. The amp puts out 1300 watts RMS at 2ohms, the subs have an RMS power range of from 75-350 watts, and you'll be driving them with 650 watts each. A better power match would be to series the subs to present an 8ohm final load. This will reduce the output power to a level the subs can handle. Or you could buy 2 more 12.1's and connect them series-parallel for a 4ohm load and each sub would still be getting 325 watts RMS, just about the maximum they are rated to handle. Hope this helps.

Amp is shutting off after 10 min of driving!! please help!!


Does it happen at all volume levels?
What is the gain setting on the sub amp?
Have you checked for 12V @ remote turn on after problem occurs?
Sounds as if the remote turn on relay inside the amplifier is losing signal, or has become damaged. If the protection light does not light up, the problem is not thermal, shorting, or high/low voltage.
The amplifier is in need of repair. This is not an end-user fix. Looking at about $50 to repair.

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.

Subwoofers


This will depend on the amplifiers capabilities.

I will give 2 different scenarios.

#1 Stereo configuration

If the amplifier supports an RMS power output close to the RMS input power of the subwoofers then run the amplifier in stereo mode. For example 150 watts RMS X 4 channels driven at 20-20khz. (If you can provide a model # for the subs and the amp your looking at I can help you further with this decision.

Wiring for this is easy and simply involves matching the connectors for 2 of the channels (Front or Rear) to each of the subwoofers.

#2 Mono Bridged mode.

If the amplifier is lower power but mono bridgable you can bridge two Pairs of channels and power each of the subwoofers this way.

Generally speaking a 2 channel bridgable amplifier will be able to at least combine the wattage of each channel into a single monural channel and in many cases its actually higher.

So you would bridge the front 2 channels into a single bridged mode for one subwoofer. and then you could bridge the read 2 channels into another bridged mono channel for your other sub woofer.

For example if you had bridgable amplifier thats 50 watts RMS X 4 you coudl very likely (Generalization based on quality of amplifier) send 150 watts RMS to each subwoofer.

Again I would need to know what amp you're refering to to provide specific wiring instructions. Many Bridging amplifiers either have a single switch that will send them to bridged mode or you would use the positive + terminal from one channel and the negative - terminal from the other channel or a combination of both.
