I don't know what you're willing to spend, but if you like Alpine the SWS-1043D woofers are a great choice along with the Alpine SPX-REF17 6-1/2" component speakers for the doors. I'm using the Alpine M-500 amp for the sub and the Alpine MRA-F350 5-channel amp for the components. No distortion... I have the Alpine IVA-W505 HU... It really sounds great...
