3 Channel set up??

[Jrock1]

Wassup people! I am new to the forum and new to the custom audio scene. In the past I have had nothing more than a sub in my vehicles. I just bought an 08' Ridgeline and want to install a "decen" sound system. My budget is kind of low so I need some help. I put in a pioneer AVIC F700BT a week ago and I want to change out the speakers now. I only want one amplifier, but it needs to fit under the seat and have enough power for a sub. Does anyone make a decent 3 channel amp?:

1. 6.5'' components up front (amplified)

2. 6.5'' coaxials in the rear (run off HU)

3. Pioneer sub/carry over from old vehicle (350rms amplified)

Any suggestions on speakers and Amp?

generally this will be a 4 channel amp with two channels bridged for the sub. this gives 2 channels for speakers, and one high power channel for the woofer.

Thanks thch! I have been looking at the Kenwood KAC-X4R as well as the Eclipse XA4200. I think that both would power my 350rms sub decently.

as always, you will want to ensure the amplifier's reccomended minimum load is equal to, or a little lower than your actual load. eg, most 4 channel amps are rated for a 4ohm load for the bridged case. for optimum economy (getting the most power per dollar) you'd want to ensure you can wire your subwoofer to be 4ohm. this means a 4ohm SVC, 8ohm DVC, or 2ohm DVC.

also, the ability to remove bass from non-woofer speakers using the highpass filter is also a benefit here.
