    ok i purchased the blaupunkt pcxb693 210 total watt for each speaker with total of 420 watt . 70 RMS and 4ohm impedence with frequency response of 50-20000hz and sensitivity is 92db if needed. i need a 2 channel amp . i heard to go by the rms which someone said i would need a 70rms amp , they also said that the peak power watt is for marketing purposes more likely. so this narrows down since i bought the speakers i am looking for a cheap amplifier (doesnt have to be top line) i was looking at jensen , power acoustic, and legacy.

    i dont have much money as im not employed i got a 89 volvo 240 dl sedan last summer and am trying a little at a time to fix it up so i got the blaupunkt speakers , jensen 400 amp and bought the wiring for it. so as soon as the weather starts warming up ill get someone to do it, so i ended up spending 121.00 . i am always looking for the bargains lol.

    I have no experience with these speakers but I don't think they can handle anyway near their rated power. I'd suggest using an amplifier that can produce between 50 and 75 watts per speaker.

For $85 i can sell you an Almani 900 watt 2 channel amp i would stay way away from those 3 brands they are all really poor quality and i can get you any major name brand cheaper.
I can get you a hifonics 4008 amp (800 watts peak 100 watts per channel rms) for $100 shipped with full factory warranty. you find an amp you like and i will get you a price. I am a factory wholesale distributor for most brands.

Why does my boss 1600 watt diablo amp cut off at high volumes

Chances are your speakers are running at to low of impedance. Check if your running aftermarket. speakers, if so they are probably wired in parralle. Change the wiring to "series"increasingly your impedance from 2ohms to 8, that should solve your issue.

Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Hopefully its not toast. .A thumbs up would be greatly appreciated if this answer is helpful to you. protective-mood-zb4bomd1rt4qms0dqd12kkt2-2-0.jpg

I have a Boss 4x50watt in-dash stereo, 2 Pioneer 270-watt max/ 40 watt nominal rear speakers, and 2 Pioneer 500 watt peak/ 80 watt rms front speakers. Do I need to buy an amplifier? Or is does the head...

You do not need to buy an amp, the only reason to buy one is if you do not think it is loud enough when you turn up the volume to max. The speakers you have can take more power than your stereo can provide, but you only need to add an amp to get more power if you want it to play louder than it does now.

I have sony laptop ; i want to connect speakers with .i have a question that if i do so then i need a amplifier or not ? if no then how much its max output?

No you dont need an amplifier. You can connect speakers without amplifiers to it. Even 2.1 and 5.1 can be connected without the amplifier. The max output will depend upon the speaker ratings, but I can guarantee you'll get sound enough to break your window ;)

I've connected like wise without amplifier and its working great.

Hope this helped. Rate it if it helped you.

Plug in external speakers w/ volume very low in HP2009m screen

check if the external speakers u plugged in came with an internal amplifier, if not then u will have to use an external amplifier to get max output from your external speakers.

Adding subwoofer

Hello dongurian,

You can add the Bass600 even if your Pioneer does not have any premap outputs. The Bass600 has speaker level inputs and you should have gotten a keyed plug with pigtail wires to attach to the speaker output. Or, you can use a line-out converter if desired.

Hope this helps.

I have boss amplifier can i use flush speakers of any other brand


You can use any brand but you need to be careful about how you connect the speakers....Say if theyre 8 ohms and you put 2 in parallel
then they equal 4 ohms etc.
If you put two 8 ohm in series they'll equal 16 ohms.
I would go to EV's website for more on speaker connections

How to hook up 2 10 inch speakers

For best results the output resistance of the amplifier must equal the combined resistance of the speakers. So if the amps says 8 ohms and you have two 4 ohm speakers you put them is series or if the amps says 4ohms and you have two 8 ohm speakers put them in series. If it says 4ohm and you have two 4 ohm speakers best to use only one. It Depends on the output resistance of the amps. It is usually written at the terminals where the speakers are connected.

400 watts delivered to 300 watt speakers the only way to do this would be to wire two subwoofers in series so that the power needed to drive them will be 600 watts to max, however this will increase your impedance on the speaker (8 ohms) load so what you can do to compensate is get an 8 ohm 600 watt resistor and put it in parallel with the speakers you will then have 4 ohms of impedance at a total capacity of 600 watts of power In other words the amplifier won't blow these out now.

Will this amp push my speakers

Whoa, I do belive your rating for your speakers are inflated. I have never heard of a 6X9 accepting 800 watts thats just rediculas, its more than my 12" sub needs. Anyways, if this amp is anywhere from 300 to 500 RMS watts you will be fine. Because the speakers are small they need very little wattage to reach there potential, usually less than 100 Watts each, and probably around 50. If you think about it most decks put out 50Watts max for each channel, because that is the max you can assume that the RMS wattage of the unit is only around 20-25 Watts of power per speaker.
