Enclosed powered sub advice


Prominent Member
I hope you can help me I am looking to purchase a enclosed sub woofer for my Nissan Xtrail. I don't want a large box in my boot space but underseat unit with great base and quality. Can anybody recommend me something. I've recently just had Hertz speakers placed in front inc tweeters to improve the sound from original Nissan stock but they sound very tinny and no base.

To say I was disappointed is an understatement as they've got good reviews and well made, but maybe they provide more mid and top range with very little or no bass. I am no expert what's so ever so advice would be nice.

I've been advised to look at at system for the underseat I will let you know what it called when I can find out. Sorry it made by a company callled Rainbow

Help would be appreciated

it's actually not an issue with the speakers,it due to the fact the oe speaker have got a high sensitivity and a low rms,so can be powered properly by the factory/Am head unit..i had the same issue when changing out door speakers in a astra a few yrs back..
