I am getting some 4x6's on Monday, the are 150 watt rms each. I want to ONLY have those 2. No 6x9's. I was wondering if i combine the wiring for front and rear to one speaker. Kinda so its 100x2. Will it work like that, or do electronics just not work like that. Just using the Deck. Thanks

 

You can not bridge the outputs of the HU. The internal amps don’t work like that. You would need a bridgeable external amp.

 

He's right eventually you will burn up the head unit.

You will need an external amp if you want to bridge it,,

I hope you relize that not much bass response comes out of 4x6!

 

I have subs, so Im not too worried about the bass in the 4x6. Thanks for the replys tho, you may have just saved me from blowing up my $240 HU. Thanks fellas

 

I would STRONGLY recommend bass blockers for the 4x6s.

 

Yes, bass blockers are a must! Try the 2400hz at 4 ohm.

 

i think his deck will have crossovers in it for the 4X6s

 

Dont worry anywho. Im getting an amp for them now anyway

 

what brand are these 4x6s? Judging by the fact that they are rated at a ridiculously optimistic 150 watts, I'm guessing they are a cheap brand. Please understand that regardless of what they say, if you pump an honest 150 watts into them, you'll destroy them. Hell, I'll bet 20 watts at 50hz would cook them in no time.

Bass blockers, as mentioned are a MUST if your amp/head unit doesn't have a high pass filter, but 2400hz is way too high of a frequency for bass blockers. For a 4x6, a 100hz or 150hz high-pass is usually adequate since they don't produce much sound below that frequency range anyway. If you run a 2400hz high-pass, you effectively turned your 4x6s into a pair of tweeters.

Anyway, as long as you don't try to send any bass to them, a good solid 20-30 watts per channel will be perfectly adequate. In most cases, even a head unit can provide enough power for speakers that are running a 150hz high-pass.

 

They arnt cheap. They are Massive Audio 4x6's. Its actually 150 Max, 50 watts rms. I didn't read the fine print :P

Oh well just means more wattage for the Sub. 500 watts to be exact

 

You dont get a very good midrange out of 4x6". that is what the 6x9" are for. 50 hz to a 4x6? I dont think so!

 

get some dual voice coil speakers and then you can use all four channels on the amp.... or you could rewire your existing 4x6... run the tweeter off of the front... and the woofer off the rear... make sure you have the right frequency cut-offs for both though... I'm not sure if the electronics on the speaker are suitable, but if they are, then you literally could just wire the front channel into the tweeter, going through the high-pass filter on the speaker, and then feed the rear straight to the woofer, (or go through the filter it has for the woofer if it has one...)

In my case my 6x9s are already DVC which means they have two sets of inputs already... makes it easy to wire them properly for any system.
