    These should do the job crossing over around 80hz which should be about right to meet your sub.

    Thanks and so these should keep my 4X6 speakers from blowing and I was thinking of soldiering these online of the positive wire because if I ever want to try any other speakers it will already be in place.

    Any other suggestions I donít know much about this kind of stuff?

    In the back or back speakers Iím running some Cherwin Vega 6X9 speakers which are just for my mids I think I donít need to do nothing to them or am I wrong???
    Thanks! RJ

    I almost bought some 4X6 Polk speakers at Fryís they were on clearance for $37.00 but I figure what I have my MA Audio or MB Quart speakers when I put the capacitor or bass blocker they should do the job just as well I hope I ordered what you recommend.

    Re: Bass blocker need help

    yeah if you have your front speakers connected to the amp you can turn on the high pass filter on those channels on the amp, this will only allow high frequencies to the speaker.

    its better than the bass blocking capacitors that other people suggested that didn't actually read your post

    Mids cross between 60 and 120 depending on size power and application. Start at 80, go easy on the power at first and play around and see what blends best and what keeps you out of trouble as far as not over-driving the mids.

    Thanks again guys for all the info and education I moved the switch on the amp and it really helped even without adjusting it Iím going to play with it and the bass blocker and heat shrink came in yesterday which I donít need but might if I ever have a stereo running with no amp to adjust the highs.



    Made a BIG difference now Car Toyz charged $40.00 to adjust all the settings on the amps and my Alpine HU what do you think guys is it worth it????

    Re: Bass blocker need help

    Today I found that HP switch adjustment knob was turned all the way up so I adjusted it some now I’m going to check where the back channel is that at which are for my 6 x 9 speakers but on my 6 x 9 speaker instruction manual it had for mids and highs and they did have some capacitors on them from the factory so if you guys have any other tips bring them on thanks again!

    If any of you guys have any input for my 6X9 to be only runnning mids and highs in where I should have the settings at look at the video it’s the same amp I have. ?
