2ch amp for 4 speakers

[Marky]

Wurd up

I have a 2 channel amp now spare after removing the massive sub box and regaining my boot space and 30kg or so, and would like to use it for something productive.

Pop quiz - am i better to run just the fronts amped, or left and right sides in parallel, or left and right in series (so each side of the car is from one channel)

Has decent speakers front and back, and amp is pretty good quality pioneer somethingorather so should be fine with 2ohm load, I\'m just not sure which way would be "best" as such for what I have

I thought about that but figured the other way is better

Is 50w not enough?

I\'d do them in parallel personally

Parallel will give you the lowest impedance and series will obviously give a bigger one. Be careful though - the average amplifier is 4 ohms per channel, only the really high end stuff is usually 2 or 1 ohm. Would hate to see you cook that pioneer. A quick model search and spec sheet will tell you. With this in mind series wiring would be the safest although you will lose some power, parallel will give you \'more\' power but somewhat risky if the amp isn\'t up to it.

Just amp the fronts and call it done. Ever been to a concert where the band was behind you?

Most Class A/B amps (which yours is very likely to be unless it\'s one of those heinously rare Pioneer Class A jobbies) are happy to 2 ohms, they just get hot. If you insist on running all the speakers, run the 2 left in parallel and the 2 right in parallel. Unless your amp has loads of grunt in which case run the 2 left in series (etc etc) for 8 ohm/channel
