This may not be what you want to hear but....


Buy another 2 channel amplifier or sell the other and get a 4 and amp your front speakers up. It'll make the world of difference.


SOmething free to do would be disconnect the rear speakers as they wont help the sq at all.

I'm no audio expert and I know it says from what you have but you really should look at amping your front comps which will offer a HUGE improvement over running them from your H/U

Going on the front speakers you currently have, get something that does a minimum of 6x20 watts rms @ 4 ohms. A bit more is always a good thing :)

Id cross the sub over at around 60 - 80 hz. Try a few different settings to see what sounds best.

If you want small then this is the amp for you:

It will definately change the way your fronts sound:) .

If you are serious about your car audio and are looking into the long term then perhaps the model up from this which is also very compact but offers more power.

thats a little expensive to be running my cheap'ish fronts though i think they would be letting the amp down! how about an Alpine MRP-T220 looks small and offers 70w rms x 2 Alpine are a good name arent they?

Alpine make good amps :)

I use that particular Audio System amp and I chose them because they were very small and actually very cheap relative to some of the other similar quality amp. I have two of them and one is for the sub and one is for the amp. Prior to this I had Alpines MRP range amp and it was quite a decent amp and very well priced too. But the difference between the MRP and the Audio System was night and day.

If you feel that you are never going to change the fronts then the Alpines the amp for you and yes its quite small so will do the job for you very well. There is also an amp by Kenwood thats quite small and I believe its smaller than the Alpine so you may want to look at Kenwood ones as well.
