No need BoomBus lah [;)] BangBus good enuf liao [thumbsup]

Anyway for the Re Audio we were looking at the SX or XXX only lah [pirate] Looked at their specs again - the Brahma have lower extension leh [:|]

Max I can spare is abt 1 cubic feet for the enclosure. [:/]

For the Brahma I need about 900w of juice - so looking for amp with that requirement in mind. PPI (but big size leh), Performa (ZD2200, 1500w @2ohms), Rockford, Lightning Audio (Storm X1.2000.1D, 1100 w @2ohms), etc. are in consideration [:/][dizzy][crazy]

Any other recommendations welcome - 2nd hand lobang also can [:)] Hoping to spend max abt $1K for the amp.

Thanks for the web addresses [thumbsup]

Never realized that the Adire Audio got no pics until u mentioned it [:p]

I PM u!

I am planning for a sealed box - do not to compete w/ u for SPL lah [laugh]

I am going Beijing end of the month - maybe come back w/ cheong Rockford [:p] or some other chinese amp [;)][bounce1][bounce2]

Anyway the Performa fits my bill for size/price/power. The amp is quite small sized against its power rating unlike the PPIs which r quite big!

Will check out the Helix amps; Re - I think too ex lah [:|]

Anyway - JL Audio's sub is apparently more SPL than SQ [:p] and require enclosures that r rather big - [:/] I have limited boot space [:(]
