Can I hook a 2-channel amp up to my car's 4 speakers?

Question

My friend gave me a 2-channel amp. The only other thing I know about it is that it is a 250 watt amp. So what kind of power does this thing output? My new Sony head unit outputs 17 RMS x 4 and 52 watts per channel.

My car gets really loud and drowns out the speakers (new 6-1/2" 3-way Kenwoods) and I have to turn the voulme up to 25 or 27 when the poor volume nob maxes out at just 34. So can this amp be used to power my 4 car speakers and give them that extra "boom" and clarity I'm looking for? If so, would I need to do anything special to hook it up?

Answer 1

yes, with inside speakers you are supposed to use a 2 or 4 channel amp

mono or class d amps are for subs

Answer 2

Honestly there is alot wrong with your ideas. First. Don't put subs and main speakers in parallel with each other on the same amp. One set is low freq and the other is higer. You need to seperate them. Get another amp for the second set of speakers. Also, switching the speakers in and out would chage the load the amp sees. Good way to screw something up with a switch turning them on and off. Just get 2 amps and have one for main and one for subs. Also, make sure the Turn on wire is on switch voltage. You have it setup to always be on and that will run your battery dead. Also, don't wire speaker to your radio/cd player and also to the amp. You will fry the setup fast!

Answer 3

if the amp is a real two chnl then it is 125 watts a side i would not recommend hooking up al four speakers on this amp it will only drive the amp harder i would only do two speakers cause you'll get a more clear sound from that set up then get a smaller amp for the front speakers also look into a cross over you'll like the adjustablity of that for total cotrol of your system good luck cam73

Answer 4

yes you can use it that way, you may get some distorsion to the smaller speakers though. 250 watt/2 =125w per channel/2 equals 62.5 watts per speaker. remember in the future, when using an amp, you want your reciever to be as powerless as possible on the output leads. this will take care of alot of your high noise and high energy humm.

Answer 5

If the speakers are each 4ohms, then yes.

If they are less than 4ohms each (i.e. 2ohms), then no.



If they are 4ohm, then simply connect the 2 left speakers to the left output channel in parallel (both speaker +'s to amp +, both speaker -'s to amp -). Both right side speakers to the right output channel in parallel.



If they are 2ohm, then you'll only be able to connect the front speakers to it. -The front ones, because that's all you'll hear over your car.
