coustic is not bad at all, the problem is that they don't have powerful models, they're quite good for door speakers or small subs. What subs do you have so we can give you some brands and your budget too
I've a cheap setup that I will change little by little . hu: alpine cda-9807 amp: xplod around 4x50watts sub:audiopipe I have a deal for a old school coustic and an USacoustics. the coustic amp is just 4x20w I'll soon change my stock frontstage too. Also Do you think rockford fosgate or mtx are good for frontstage?
man i'll give you a little setup and you will never regret, buy one kicker cvr dual 2 ohm, buy directed 600d, buy one infinity component and buy 2 6x9 in the back, then you are gonna be happier than ever. You can use your amps bridged, the ones you got for speakers and components
