Hey all I have two old school VWs and a honda civic . Trying to figure out what to put in them. The honda has bass and some decent speakers. I am building a 1961 VW beetle with a sliding ragtop and I want it to be loud with some bass. I am new to car audio. I have Infinity kappas a pair of 6.5 and 6x9s. I need some advice on good decent priced sub and amp. Thanks.
