I haven't been around audio equiptment in 15 yrs. or so . Can someone tell me what my system needs to get the best sound possible ? This is what I have . First you need to know what is up on the deck that is outside . a set SPR-M700 ALPINE 7"two way marine . a set ES 620 GOLD 6.5 CDT component . Two Kicker COMPVR 15" . four sets of marine ready 200 watt kicker tweeters . In the cabin I have one 13.5W7 JL . a set of ES-01 GOLD CDT audio 1" ultra comp. grade silk dome tweeters. a set infinity 325 watt marine. the amps .... t1500 rockfordfosgate mono. zx1500 .kicker . and pushing my highs ...pdx 4.150 600 watt alpine . right now my pdx 1.1000 alpine isn't installed . I really don't like it . I've been thinking about a zx2500. is it too much ? ... is the alpine pdx4.150 enough for all of my highs ? I have the rockford t1500 pushing the two 15" compvr . 1000 watt . is that enough and how should I wire the voice coils ? I have the zx1500 pushing the 13.5w7 JL. Right now I have all subs wired in series . To power my system I have a SPC5050 stinger pro farad hyrbid digital compasitor . two SP2150 stinger power2max batteries . I installed a yamaha ef3000isb generator to power my ac components like a 3 bank battery charger and much more .
