[QUOTE="jdc753, post: 202667, member: 52"] Glad to help out, honestly from what it sounds like for you I would just jump on a good deal, probably around the Hifonics level, figure it will make a few watts less than its rating but it will still BLOW the HU power out of the water. HU power is around 17-20wRMS while the amp will be most likely 50-100w, so you are going to at a minimum double your power which will net a minimum 3db gain. Plus with the more power comes greater cone control of the speaker as it cycles (clarity) and less chance of clipping at higher volumes (distortion and speaker damage) For what you are looking to do a class D amp will be fine. If you were going to add some higher end component speakers and looking for that ultimate fidelity then A/B all the way but I think the gap in sound quality is getting smaller and smaller between A/B and D class amps. Yup Class D is a much more efficient design allowing for the smaller foot print multi channel amps like Alpine PDX and JL HD amps. Generally Class D amps were considered only good for subwoofer duty as their shortcomings in sound quality aren't as critical and their higher efficiency (thus output) worked well, instead of having a HUGE A/B amp. Basically what it comes down to is differences in THD (Total Harmonic Distortion) Dampening Factor, and signal to noise ratio. Just looking quick over the specs on the new line of PDX amps it looks like Alpine has the Class D stuff all figured out, and I would assume the same with JL's HD line. This actually hits on most of the points fairly well, see the items they talk about on the left of the page, [url]http://www.alpine-usa.com/product/view/pdx-f4/[/url] [/QUOTE]
