Ok I just started this thread so I can meet some people who actually KNOW what they are talking about when it comes to apline type r 12s, and a boss Rev-2000d. My system is as follows:
1990 Chrysler Newyorker
90 Amp Alternator
2 Alpine Type R 12's
Ported Alpine Box
2 50w rms Premier 6'9s
1 farad Pheonix GOld Cap * that does jack **** really not even hooked up currently*
2 Spr-134a 5 1/2 Alpine Door Speakers
Apline cda-9807 Head Unit
Now let me tell you my system's SPL is ****ing amazing, along with the sound quality. First off you guys really underate the boss REV-2000d amp. Ok ya I know boss makes some ****** stuff, but you guys shouldnt really say anything unless you really try it. I have my subs wired in parallel at 1.1 0hms, for about a year now. It works amazing with that amp.Yes I will tell you right now id say that amp puts out about hmm 1000 rms at 1 ohm, even though it claims like 1400. Yet it really is a good amp, you guys always reccomend the jbl 1000.2 over it, and have you ever tried to run that thing at one ohm? It wont last more than a month if Iwas running the load I am now. I was going to sell my amp for like 600 canadian, and invest in a audiobahn digital amp. Yet I think my Head unit makes any digital amp pretty obsolete. Also the Alpine type R's along with all of alpine products are HORRIBLY underated.I know a guy who runs a MrdM500 to each sub, and it just pounds. Yet at one ohm I am GLAD that my amps puts out the power it does, since I doubt my alternator nor subs would be able to take it.
I went to a Competition and took 3rd place which is pretty amazing since I was competing against two 15s. I was rated at something like 135 dbs.
