I have a JVC headunit (rated 4x 45w RMS) with a pair of magnet 6x9's (150w RMS each)
I have now bought a 10" Free air sub on ebay, and am currently bidding on a amp.
The sub specs:
10" Component Subwoofer ( Free-Air )
400 Watts Output
4 Ohm Impedance,
Frequency Response : 20 - 3,500 Hz,
Can Be Used in a Sealed or Ported Enclosure,
Sensitivity : 92 dB,
33 oz. Strontium Magnet
^^^^ COST £3.20 ^^^^WOOOOO ^^^^
And the amp, is a Longmill JL900 (cant find any specs, but has run 6x9's and a 440 sub according to ebay)
All i know is that,
2 Channel Amplifier
Usual bridging facility, with overload thermo protection, low and high level inputs, gain level control, treble and base. Visual led power and protection indicators.
High powered Amp, but not quite sure what out -put, but was running 6 x 9`s and a 440w sub.
So my question is, if i wire the amp to my Headunit, can i wire the 6x9s to the amp so i can get the fully 150w of the speakers aswell as my sub?
cheers,
Jordie

no, with that amp u can either run ur 6x9s or the sub. i would possibly run both but not very well.

if you are running the 6x9's from the headunit then you need a crossover to block out frequencies less than 70hertz, you can sometimes do this from the headunit or you can buy in line filters which block out the really low frequencies.
The reason for this is with the volume cranked up you won't be able to hear the 6x9's distorting for the bass from the sub, also you will get a cleaner sound and be able to give it more volume and you're 6x9's will last a sight longer.
