So i only have like ~180 watts from the back two channels on my amp it is a JL J2 320.4. Im on a budget like mad here unfortunately and that amp was $99 not seeing anything else for that kinda money recently. So i snatched it up. I am running the front two channels on boston acoustic rallye series 5.25 co-ax, the back two channels will be bridged to a subwoofer that amp will do 60x4 at 4ohm 80x4 at 2 ohm. Ive read they are a tad bit underated so 160-180 watts is all i can expect. If i buy and X will that be enough amp sealed? I dont really think i wanna get a ported box right now. Ive not had bass for 3 years+ so im kinda starting out very slow but quality cause i may never upgrade again.
