    I was doing good about not tinkering with my truck until i found Tacoma World. TW + down time at work leads to money spending and ripping things apart in my truck.

    Heres what i'm doing, over the years i have accumulated stereo parts. I have an old set of pioneer TS-TRX800's. I also have a kenwood 250 watt amp (KAC-529S). I figured i give building a sub for my double cab a shot since i have all the parts and wood. I have scavenged one of the truck speakers and built a new enclosure for behind the driver side rear seat. I just finished the box last night and now doing my research on hooking it back up. My new setup will only be utilizing one of the subs (i used both in past installations). I just happened to notice that the sub is rated at 200 watts max music power (75 watts nominal). The amp is 250w. I was going to "bridge" (im not up on all the terms) the sub as according to the recommendation for a 1 sub install in the instructions. The specs say Max power--normal is 80w x2 and bridge is 250w x1. Its a two channel amp.

    do i have too much power for this sub to do the bridged option or should/can i hook it up to just one channel to send less power to it? which is better to hook it up to the left or the right channel?

    thanks



    thanks

    Bridge it and don't worry about it.

    Just make sure your amp is stable in bridged mode for the ohms value of your sub.

    You'll be fine.... when you go to adjust the gain, be smart about it, don't just crank it.

    if you have questions, find a local shop and flip one of the installers $5 to help you adjust it. Installers love a free lunch

    thanks guys. this site is great. with what i will be listening too i wont be maxing it out. not looking to rattle the truck just a little more than whats there. hopefully this box works out. never made one before. took 2 tries to get something that fit the space and my salvaged sub. so far the the budget has been just 20 bucks for some glue, calk and extra wood. if it works ill add some carpet and have 2 less things in my (i may need this some day) box.

    A few hundred watts over what its rated wont do anything. Focus on keeping the distortion low, as thats the main killer

    you clip an amp which results in distortion, yes. who the hell says "keep the clipping low"???

    but thanks for the so called correction

    For those who aren't electrical engineers, the term distortion on it's own typically refers to THD (total harmonic distortion). This is what most people think of when they hear the term 'distortion'. So when you say to "keep the distortion low" 99.999% of individuals reading that post will assume you are referring to the ONLY AMPLIFIER SPECIFICATION that quantifies any type of distortion...THD

    We have a special term for waveform distortion which isn't even close to being the same thing....it's called clipping. The term exists for a reason.

    I made the correction for clarity's sake so others know what the hell we're talking about.
