the stinger one's are decent, but can get freaky on certain sound systems, they dislike certain floating systems, and I've never used one in a honda so I won't give my word on them. The best to me is a soundgate LOC4, it's one of the few line converters that gives you 4v outs. If you want 4 channel outs the soundgate LOCHV4A is the creme of the crop for LOCs(Line Out Converter). I've used a P.I.E. PDC-LOC4 on someone's car before and it was pretty damn happy, not quite as nice of response as the soundgate, but still very acceptable, and for $50 for 4 channels you can't beat it, although personally I prefer the Soundgate because it has higher voltage outputs which equates to a lower SNR.
