Car Forum / Driving, Maintenance, Tuning / Car Audio / May 2004Need some help in connecting a Linertek 800W 4 Channel to Pioneer 12" DVC
I have a Linertek 800 Watt 4 channel amp and it runs my new Pioneer 12" (800 Watts maximum power handling (350 Watts nominal) Carbon series) Fine, but i want to get some more kick out of it. I can bridge the 4 channels to 2 channels giving 400Watts to each channel. So is it possible to connect both channels to the dvc sub? and is it possible for the sup to get damaged? Thanks What's the impedance of each voice coil on the sub? If each coil is 4 ohms, then you should be able to bridge your 4-channel amp into two channels, and send one channel to each voice coil with no problems. If each coil in the sub is 2 ohms, that's probably a lower impedance than the amplifier is capable of driving when bridged into two-channel mode. As long as the impedances are okay, there's nothing inherently wrong with driving each voice coil with its own channel. Make sure you have the gains for both channels set the same to maximize efficiency. I'm more concerned about the power handling of the subwoofer. If bridging your amp into stereo mode will really provide 400 Watts per channel, that's almost 800 Watts total for both channels, and you're talking about feeding both channels into a single sub. It will work, but you'll have to keep the gains turned down low enough so as not to damage the sub.

Im am not that clued up with ohms and watts and rms, but i heard that if a sub is 800 watts u can put 800 watts of power into it to run at its best. But not 800 watts rms. Is that true?

Your amp should be fine when you bridge it into two-channel mode and feed each channel to one of the voice coils. I still haven't found any information on your amplifier, so I don't know if the 400W per channel in bridged mode is peak power or RMS power. Keep in mind that your subwoofer is only designed for a total of 400 Watts RMS power, so you may need to turn the gains down on your sub if it puts out much more than that in bridged mode.

I dont know how much RMS this amp is. It doesnt say anywhere on it or in the booklet. So i guess its 800 watt peak power.

To me it means their amps probably put out maybe 1/4 the power at clean levels that they are claiming. I thought the feds had passed a law decades ago that compelled manufacturers to state their power clearly in watts RMS and the % of distortion at that level. What is really useful is to know the watts RMS and % of distortion at every level across the audible spectrum.  SignatureTodd Ya i noticed that so i guess i can put all power to my sub then. Coz my 800 watt amp is prob like 200 - 300 rms ? Am i right? Well i cant find any info of my amp on the web and i live in South Africa so i guess that law isnt here. :( I bought it about a year ago and at those times i just wanted sumthing to play my 7x10's and a old Pioneer 12" IMP 350watt.
