I plan on installing a system in my vehicle, but my dilema is that I have two different sets of amps and I'm not sure which is better. I have PPI (460ix,2 100ix, 200ix) ang Phoenix Gold 9xs2500, XS4600). I have an older but never used Alphasonic Q series 10" sub. Old silk dome Nakamichi tweeters and CDT Audio 5.25" Co-axials. I want the best performance from the amps for all around listening. Everything from Rock to watching movies in the van. Any input will be appreciated. Thanks
