Don't want to run this off topic, but I've got question that relates. I have a JVC HU now. It does the job, I like it, so there's no real motovation for me to upgrade it, except for the fact that it has 2 Outputs. Right now, I use the Rear output for my Sub Amp, leaving only the Front outputs left. Now, I want to add an amp to power my speakers as well ( Have a nice JVC component set that I'd like to amp, and my rears could be amped as well, but it can't be a four channel because I don't have the three outputs. Now, what I got from the above tells me that I can use a 2 channel amp, wire my 4ohm speakers together (Let's say left front and rear, and Right front a rear) to create a load of 2ohms per channel. But, you say I won't be able to use fading capability. Now, is this just for the speakers, or for the sub as well, as I'd like to keep the ability to fade up front so the sub isn't as loud? (I don't have sub control on my HU). As for fading the rear speakers, losing that capability doesn't really bother me. Is what I said right? lol

get a 4 channel use a y adapter to feed 2 times the right and left and then you should be able to raise or lower gain on the amp as of a fader lol thats what im doing for my front end since i have 4 speakers works fine for me should work for you too

The best solution is to get a 4 ch amp with pre-out jacks.That way you can still use your deck fader for front and rear and feed your sub amp from the 4 ch.

if you still want to control fading between front and rear speakers, then get a dual amp balancer( front will be split into 2 pre outs with a controller to fade between the two, and you can keep your rear out for your sub). If you don't need fading between your main speakers you can use the rear out for subs, then you can still control the sub level by fading to the front, and run an amp of the front output at 2ohms for your main speakers.

Well i was on the hunt for an AMP this past weekend and purchased this amp
at 2000 Audio the guy in the showroom says this will work great what do you think

please reply apparently the Alpine amp they no longer carry and if i remember correctly the only difference between a 2 channel and 4 channel amp is the fade from front to rear which i never do anyway so i can just bridge the speakers will this amp be too powerful for my speakers.

perfect! 75x2 rms @ 2ohms, means that each speaker will get about 37.5 watts. Just right for your speakers...enjoy!

I,m a little confused here i was reading the install instructions and it had a warning about running your speakers in parrell so i called the number for Pioneer tech support and they are telling me that the amp will blow my speakers unless i turn the gain control down to just under half he suggested that i either return the amp and get the GM-4300T 4 channel or turn the control down man i hate not knowing everthing about what i,m doing would i be better off returning this amp and getting this or what

Well i decided to exchange my Pioneer GM-3300T 2 Channel Amp for an Alpine MRPF250 4 Channel which to me was a better option considering the Alpine is a 4 Channel this way i will have fade control if i ever decide to use it and it is more suited to my speakers or so i have been told i called Alpine tech support and he said this was the best option for what speakers i,m running.

well that's a better option due to the fading capabilities. The warning is for 2ohm mono (bridged) operation. Most amps are only stable to 4ohms in bridged mode (where you combine 2 channels to become a more powerful single channel, 2 ch to 1 ch, 4 ch to 2 ch, etc...). The only way your amp would have blown your speakers was due to overdriving them into distortion, or possibly running them for a long period at nearly full power, as your speakers are rated for 30 watts rms, and the amp would deliver 37.5 watts rms. It's kind of hard to explain, but to give you an example, my front midbass speakers are rated for 150 watts rms, and I power them with 300 watts rms each...and I've never blown a speaker in 25 years.
