I think while my truck is in rebuild mode I will go ahead and upgrade or change to a newer unit. I love the alpine but want to look at something different. Looking at the deh-80prs or the avh-P8400bh. Sq wise the 80 looks like the choice but im sure I would be happy with either. Any other good dd units out there? This is what I have now and will be letting go cheap to anyone interested http://www.crutchfield.com/S-lCerWQCN13n/p_500IVAW200/Alpine-IVA-W200.html#details-tab I want good control of eq and options for hpf and lpf. Any other opinions? I have a alpine 600 watt 4 channel that will cover the mids and highs unless I pick up an additional small 2 channel just for the tweeters
