Guys can you help me to decide sa subwoofer na gagamitin ko poh sa SQL set up sa advie ko poh. I prefer to use NBN active sub poh sana kasi ayoko poh ng bulky speaker set up lalo na poh na gamit na gamit ko poh ung back seat ng advie ko. I want underseat poh sana na 8" lang na model NA-818APR (e2 poh ung underseat) and NA-868APR (e2 poh ung parang toolbox) lang poh ung pinagpipilian ko since limited budget lang din poh. Help me decide which is better on those 2 models of NBN specially sa mga nakagamit na poh ng ganitong mga sub please help me.

My cousin poh kasi is using AVT na kamukha poh nung NA-868APR ng NBN and i found out na ok na din ung sound para sakin and halos may bayo na din sa dibdib kapag nasa loob ka ng sasakyan. Can't afford poh ung price ng AVT compare sa NBN eh kaya please help me to decide please....please....please
