Okay here's the story: I got 2-12" Type Rs (SWR-1241D the old 300W RMS versions) that came with sealed boxes. The amp i used to power them was A Cadence TXA-3002 600W RMS 2 channel amplifier. I switched from sealed to ported (ported box specs: 2.3 cu ft before sub and port displacement and tuned at 40Hz) and ported didnt really sound that great so i was thinking the box was not made correctly and it was made from alpine specs. I've been told my amplifier is not giving enough power to my subs and that my subs are being underpowered and am only getting maybe 300 ish watts to both the subs. I was recommended to get a JL 500/1 to put less strain on the system (stock electrical system with aftermarket battery) and that i was told it would pound these Type R's much harder. Now im confused if i need to upgrade my electrical system or will this JL 500/1 v2 amp help me out? Help!
well you're just improving quality not quantity of power.
You should get a bigger amp just in case you wanna upgrade... that's my opinion cuz seriously... 40HZ is high.. maybe check your box DIMENSIONS, but i think that's enough.
actually i do own a vw bug 1973 with a 55 amps alternator feeding a US AMPS MD3D 2000wrms and i just have upgraded the ground to 1/0 gauge, i got a kicker 1/0 gauge amp wiring kit thats it...no need to change the alternator bud.
