Do I need a 4 channel or 5 channel amp?

[chuckle490 10+ year member]

I just installed my monoblock class D amp and my sub and I want to amp up my 4 6x8 speakers. How do I wire up 2 amps or what? Can I have the two amps going to the head unit separately? I'm a total noob when it comes this stuff so thanks! Im running a sony CDX-GT260MP head unit, with a sony XM-1s monoblock amp going to my kicker 10cvr124. I want my amp to rms at around 125-150 per channel. Thanks!

you can run a 4 if your deck has at least 4 rca outputs.if not you'll need an eq to separate the signals for frt rear and sub.whats your budget for the amp

How much do you think would be good? I was thinking like 150 for just the amp.. but If need be ill go higher.

125-150watts RMS is a bit optimistic for $150, but also unnecessary IMO. What 6x8 speaker needs this power? For 150 you can probably buy something like a PPI Sedona, PPI Black Ice, or MB Quart ONX4 4-channel amplifiers. I would have preferred PPI Phantom P900.4 as it's much smaller, runs cooler and it does provide more power, but usually costs >200.

Yeah after re thinking, my speaker peak at 700, so i prob want them to be running them at like 400-480, so something like 120x4 channels. I'll check out those!

You'll like the American bass vfl mini. 120 x 4 rms at 4 ohm it's a little more than you wanna spend. But if you want quality it will cost you

Hmm I've never heard of that brand. I'll check it out, do I need to get a class an because I am running it to my mids and highs?
