Kicker Impulse 652XI
with
2 Rockford Fosgate Punch Stage 2 10's
So i have this setup in my car, in a slot ported box
any recomendations in wiring setup? or do you guys just think i should get a newer amp?

do you have the model numbers for the subs are they dual 2 ohm dual 4ohm?????? single 2 ohm single 4ohm???

weirdly enough...they are 1 single 4 ohm and one single 2 ohm

hehe... thats a funny pair of subs u got...
anyways.. that amp seems to be a 95wrms x 2 @4 ohms..
how have you wired the subs to the amp..???/
if you have wired one sub to each channel then your 4 ohm sub is getting 95 wrms... and your 2 ohm sub should be getting somethign around 140wrms, but again at 14.4 v ..... that means under real time application your subs are only geting some thing around 80 and the other around 120....
those are a pair of under powered subs...
you can definitely have a better bigger monoblock amp to run these subs. so that these odd subs can either be wired for 1.33 ohms or 6 ohms..
and whatever way u want to wire your subs, u need to insure that you get a stable amp that supplies enough juice to the subs at the total impedance depending upon parallel or series wiring ...

Yep, that's an odd combination alright. Consider wiring both subs in series, (Net 6 ohms) and bridge the amp MONO. It's a safe range for the amp.
A better route is to replace the 4 ohm sub with a matching 2 ohm version and 1 sub per channel.

what if i could get an amp that was stable at 1 ohm and wire them in parallel to have them at 1.33 ohm? if so, what would be a stable amp for this ?

With this sub combo, if you wired them in parallel to the amp, it would net out to about 1.3 ohms. The 2 ohm sub is also going to play about +3dB louder than the 4 ohm sub. Anyway you slice it, these subs are mismatched.

Those are 150wrms subs...
means we meed a 300wrms delivering amp either at 1.33 ohms or 6 ohms...
an amp that nets around that kind of wmrs @ 1 ohms is not usually the case as i dont know of any such 300wrms amp stable at 1 ohm... probably must be there but definitely expensive ... and an amp that nets such wattage at 6ohms would actually be an amp thats around 500wrms@4ohm ( around 900wrms@2 ohms ) which is again an unecessary expense looking at the power these subs need ...
both these are expensive when compared to what your subs need..
its absolutely advisable to go the way ol' swez suggested..

A quick check showed that the sub you need for a proper match only cost 55 to 88 dollars...Even if you were to upgrade the amp, it only makes sense to have a matching pair of subs. A few bucks spent on a sub and you will be good to go...or bump..
