new to this board so bear with me...

for the rear of my van i have a Vibe Slick A4 amp details powering a vibe black air 12" sub, boston acoustics s35 speakers here and a set of infinity kappa 6x9s here

currently i have bridged two channels to power the sub and the high pass filter enabled to power the 6x9s and 3.5"s.

firstly i'm not sure if this is the best way to run the sub - it has a dual 2ohm coil and im not sure if im making the most of it and the best for the amp - any advice on wiring this would be awesome but it does work!!

secondly i want to get the most out of the 6x9s and 3.5"s without installing another amp for just the 3.5"s as the headunit distorts them at high volumes and they can't handle the power the 6x9s can. Can i do this successfully using a passive crossover? Will this give bad resistances?

i know the basics but not exactly sure how to apply it all. Front has components powered by a 2 channel amp and works wonders, back is a bit confusing currently. i can post pictures if this'll help!!

Cheers

Rich

Hey Rich welcome to the forum. Wiring your sub in series is the best you can do. Getting the most performance will depend on the enclosure. Obviously, using Vibe will limit the performance to a degree, but that shouldnt stop you from getting the max out of the system. As far as the high's, I'll assume they are wired parallel, which YES can be difficult to find a median to make both sized speakers happy. Ideally, another 1ohm stable amp for the sub would be the key . Since it may not be a reality, you can add a capacitor to the BA's to resist the lower Hz going to the speaker. Finding the right cap to do this is/can be essential to the quality of sound you'll get. There is a mathematical formula here on the site that you can punch in your info and get a idea of the Hz range each size cap will honor for you. I think there is a brand called Bass Blocker or something that already provides the actual Hz it resists, but in ?lamens? terms . Keep in mind that your on a 2ohm circuit so you may still need to resort to the Hz calculator to see the actual Hz range your getting. Good Luck, hope I helped, please post results of whatever you find to work the best for you.

cheers man good to know that im on the right track

its it ok to run the amp in 3 channels; two channels running at 2ohms for the mids and highs and the other two bridged for the sub at 4ohms....?

gona add a passive high pass filter for the BAs in parallel with the 6x9s will see how it all goes

cheers again
