Hey Guys,
I am currently building a system in my truck so i am limited on space. I have a set of infinity kappa compnents in the front doors, leaving factory speakers in back door for fillers, and running two infinity 8" subs under the rear seats. My question is how many channel amp would i require to run this efficently. I know that two seperate amps would be ideal but space is very limited and if i could get away with one amp that would be ideal. Any advice would be appreciated!
Thanks

 

you could use a 5 channel amp... run all 4 interior speakers to the 4 channels, then on the 5th channel connect your subs. depending on they're impedance, connect them both together then run 1 wire to your 5th channel (sub channel). Like I said, all depends on the ohm load of the subs..

 

So i could use a three channel amp then. I could run my front components on the two channels, rear factory speakers off the deck, and wire my two 4 ohm subs in parallel to a 2 ohm load off the one remaining channel. So as long as i get an amp that is 2 ohm stable i should be okay, right?

the two front speakers would run 4 ohms on the two front channels of the amp and the third channel would run on 2 ohm. I was just confused and wondering if thats how a 2 ohm stable amp worked, where you could have two channels run on 4 ohms and the remaining in 2 ohms, or do the amp have to run all channels on the same ohm load.

 

Get a powerful 4 channel

Channels 1 and 2 = Front components

Channels 3 and 4 bridged = cannot run below 4 ohms in bridged mode

Just make sure your sub is 4 ohm...

 

4 channel amp is what you want

 

My bad, you wanted to run 2 x 8inchers... To run them both on this amp, look for dual 4 ohm drivers.. RE RE's come to mind (got a pair in the gf's car) don't skimp on enclosure volume

 

I have 2 SVC Infinity 4 ohm 8" subs. With a 4 channel amp can two channels run in 4 ohms for the components and the other two channels bridged and run in 2 ohms if i wire the subs in parallel.

 

Not typically, most 4channel amps are only 4 ohm stable when bridged...but check your amp's specs to see if it can be used that way.
