ehall8702 Posted January 25, 2013 Report Posted January 25, 2013 I just got a pair of MB Quart QM 160 woofers and some MB Quart tweeters, unfortunantly no x- overs. i have a kenwood 4 channel amp running my mids and highs so i figured i would run my 5.5LF woofers and my MB Quart woofers on channels 1 and 2 and then run the the MB Quart tweeters and my Boston Pro tweeters on the 3 and 4 channels. I only have one set of passive ( after the amp) x-overs, will it be ok if i run the tweeter outputs of the x-overs at 8ohm? should i wire it to 2 ohm? what effect will that have on final load the amp sees from the x-overs? for clarity i wont be hooking up the woofers to the x-over just the 4 tweeters. I will be getting an active x-over in the near future just need to be able to keep my stereo running until then. 2009 Silverado 1500, 7.5" lift, 37x12.50r17s, Built Gen 4 5.3L ( 4.8l flat pistons, decked 243s, SS2 Cam, Pac 1218 springs, ported intake, 120mm TB, Long tubes, 3" duals HP tuner software tuned by me), 4l80e swapped and 4.56 gears.

Carbon Posted January 25, 2013 Report Posted January 25, 2013 Just a question. Why are you mixing and matching tweeters?
ehall8702 Posted January 25, 2013 Author Report Posted January 25, 2013 cause its what i have and both are great tweets on their own, figure they couldnt sound bad together! 2009 Silverado 1500, 7.5" lift, 37x12.50r17s, Built Gen 4 5.3L ( 4.8l flat pistons, decked 243s, SS2 Cam, Pac 1218 springs, ported intake, 120mm TB, Long tubes, 3" duals HP tuner software tuned by me), 4l80e swapped and 4.56 gears.

Carbon Posted January 25, 2013 Report Posted January 25, 2013 Are they the same ohm? Do they both do the same rated?
ehall8702 Posted January 25, 2013 Author Report Posted January 25, 2013 both are 4 ohm and the power range for mb quarts are 60-130 and the bostons are 60-400 shouldnt be an issue of over powering them im more worried about what ohm load is to x-over and what final load is to amp.... dont have the car handy to hook up multimeter and see they also have very close hp freqs also 2009 Silverado 1500, 7.5" lift, 37x12.50r17s, Built Gen 4 5.3L ( 4.8l flat pistons, decked 243s, SS2 Cam, Pac 1218 springs, ported intake, 120mm TB, Long tubes, 3" duals HP tuner software tuned by me), 4l80e swapped and 4.56 gears.
