can a 4 channel run this?

Question

I bought a Alpine MRV-F345 ,75W x 4 car amplifier,RMS Power Range : 150-300 Watts, Can anyone tell me if I can run 2 RMS 50-300w subs plus component speakers with this amp?I wanna hook it up with 2 subs and 2 sets of compoent speakers and don't know if that's possible.And which one is better for just subs,bridged into 2 channel amp or just single channel mono amp?Thank you guys

Answer 1

It's possible to run two component sets and two subs from the amplifier, but you may find that the subs don't get as loud as you'd like. A lot depends on the impedance of the subwoofers. 2 ohm or 8 ohm subs would probably work better with that amp setup than 4-ohm subs.

The question of bridged 2-channel vs. mono amps also depends on the subs' impedance. If your total impedance is 2 ohms (which is what you'd get with two 4-ohm subs) then a mono amp is usually the best choice. If the total impedance is 4 ohms (as with two 8-ohm subs, or DVC 4-ohm subs) then a bridged 2-channel amp will probably give you the most power for your money.

Answer 2

A 4 channel amp is mainly for regular speakers. Give each speaker equal amounts of power to give them better sound. If you want 4 subs then you need 4 mono amplifiers if you want them all to be clear and loud. Using a 4 channel amp for 4 subs will not be giving your subs enough power and perform efficiently or effectively. If the power to the sub Is too low, it could destroy it faster than giving it too much power. If you also include the amp and subwoofer specs I can give you a more detailed answer.

Answer 3

sure, it's possable a couple of ways. If you want it to work right, though, the way to do it is to tri mode the amp, front and rear. Tri-mode id where you have the left, the right and a mon channel from 2 outputs. You will need an inductor(choke) on the sub, but if you do it this way, you will still have stereo, be able to fade front to rear and you aren't risking damage to your amp

Answer 4

yes yuo can do that it will work just fine
