Im helping a friend on getting his first sub. I've been metered at the headrest on tl 128.xx db with my old sub, pathetic I know but it was a single 8 on 250 watts. That's the only set up he's heard and he thought it was great at first but i know he wants loads more, as do I. I got my sa-15, zx1000.1, custom box, and wiring for $520. But I know he's gonna want as close to that in terms of loudness as possible. I was thinking:
Amp: Audiopipe APSM-1300 2000W Mono Mini Amplifier : APSM1300 : $108.95 : VMInnovations.com
Box: custom ported or sealed? I know ported is much much better but price is an issue and idk if he can build himself.
Wiring: best would be 1/0 awg but 4 awg probably for budget purposes. Also: big 3 yes or no?
Sub: so many options. anything decently cheap, d2 that can handle 1000 wrms, or d4 that can handle 600 rms.
What do you guys suggest?
