ebay sub box any good?

[celicagtman]

hey guys so i jsut bought a pioneer ts 3002-d2 sub which is a 12" 1200 wat and 3500 watt max sub. and also a Pioneer Gm-D8400M Mono Amplifier With 1200-Watt Max Power 300 watts RMS x 1 at 4 ohms (600 watts RMS x 1 at 2 ohms)..i heard that its best to use a 1.25 cf box. i found a really nice looking box on ebay for 55$ thats 1.25 cf and looks good. i was wondering if its any good.

No. No its not.


Are those ports? I can't see if they're ports or just decorative circles. Hopefully they're just random circles to add flash, because it doesn't mention any tuning frequency.

That box is 1.25 cf before displacement. You probably want 1.25 after displacement. A correctly designed ported box will outperform any sealed box. But a crappy made ported box will be...well...crap.

Max ratings mean nothing. You should only look at the RMS rating.
you apparently have a 1200w sub and a 300w amp. It appears your sub has dual coils, which are each 2 ohms. these can be wired to 1 ohm or 4 ohms. Your amp doesn't support 1 ohm loads (it will over heat, see the 'my trunk caught fire' thread in the general section ;))

where did you buy the equipment from? Do they have a return policy?
