So ive decided to just go with one alpine type R 12 in the ported box, i was planning on using a hifonics amp, the bxi1208d. I was just wondering do you think that amp is ok and if so then which type R should i buy, the dual4ohm or the dual2ohm. The amp is 1 ohm stable so i was thinking i should wire it for 1 ohm and just adjust the gains. How does that sound? Also I was thinking would i need a cap? I was going to go with a 2 farad cap, something like the cheap boss capacitor. Then i would need wiring and be good to go. I have an alpine 9883 and Arc fd4625 up front maybe an Arc amp for the front too. This is just a lil setup to upgrade from stock, nothing fancy. I wanted to get some fill for the ported box too, any suggestions would be apprieciated guys. thanks in advance.
