I have alpine type r 2-ways in my car and I also have a 10 inch jl audio sub (believe it is 10w3v2 dual voice). I also have an aftermarket headunit.

Currently i have a class d amp powering the jl audio sub.

I figured the amp is huge and made for high power setups. I was thinking about maybe switching out the sub only amp for one that will power my speakers as well as the sub. Any suggestions on a good bang for the buck amp that will do this? Trying to keep costs down.

Bump please

Dont know how many speakers your wanting to power total but kenwood makes a pretty nice 5 channel amp that is pretty small in size but really good power levels. I have it running in my wifes impala powering a 12" kenwood and 4 type R coaxials. Sounds really good.
KAC-7005ps is the model number I believe, I think it runs about 350.

Mostly just trying to power the two door speakers and my subwoofer. They dont really make any three channel amps do they?

Bengi09

yes they do make 3 channel amps, JL makes one in there XD line that's pretty nice. It runs 430 and is in a pretty small chassis. really nice amp for what your wanting to do

Anything worthwhile that is cheaper?

Check out the kenwood excelon xr-4s. It's a 4-channel amp that is tri-mode capable which means it can be bridged to run as a 3-channel amp

your best bet is to find a 4 channel that is 2 ohm bridged stable, not just 2 ohm stereo stable (4 ohm bridged), but that is the tricky part as most are 2 ohm stereo stable not bridged, you could also look into some 5 channel amps and run everything off one amp, but the trick there is finding one with enough power to push the doors on the normal channels, but what you'll then run into is the sub connection is gonna be way to much power for that sub.

Using a 4 channel amp as a 3 channel is more for people that have one single 4 ohm voice coil sub the jl you listed appears to be a dual 4 ohm.

they biggest issue is your sub and your speakers power ratings are so different that anything powerfull enough to push your sub would blow your alpines and anything low enough for your alpines would barely move your sub, unless you can find something that does 75 watt RMS @ 4 ohm and is stable bridged at 2 ohm with 300 watt RMS, but good luck I can't find a 4 channel thats 2 ohm bridge stable (only 2 ohm stereo stable).

a dual 4 ohm sub is just not what you want in this situation, you would be better off with either a single 4 ohm or a dual 2 ohm (you could wire it in series to the bridge of the amp to be a 4 ohm load), but there's no point in doing that to a dual 2 ohm unless you plan to upgrade the amp later, as the single 4 ohm will be cheaper and better suited to this job.

Honestly the JL XD500/3 is an absolutely perfect fit for you. It can be had for $300 total which is NOT that bad. It matches up to each of your speakers perfectly.
