AA98hoe

I just ordered two more xl 18s for my tahoe will be running two DD m4s strapped at .7 ohms so looking at 8k rms plus i want my box to look like steves as far as height and rear port. and want it tuned in the 30s somewhere anybody have experience and what numbers should i expect? i would love low 50s. i know what most of you are going to say build boxes till you get it right.also whats the minimum i should stay off my rear doors with the port? ive built 3 boxes for my two 18s i have now and port up subs up which i have in there now pounds the hardest

trying to post pics but dont know how wow

I jumped ship from DD woofers a couple months back after hearing some lvl5s at a show.my first encounter wit my lvl 5 18s wasnt a good one. i snapped the necks on three of them in 3 weeks.Rusty worked with me throuout the way needless to say the fed ex people started to know me by name.lol i was having issues with my m4s being strapped at 1ohm and not liking any clip. so i switched to xls and raised the ohm load to 1.4 and wow! these things slam! this is the loadest my tahoe has ever been. actually hurts a lil. IM going to pound these for a little while then buy two more.I just wanted to say thanks Rusty,Anna,and christopher. for great customer service and awesome product. when i can i will post picks of my install.
