Added another amp to system now subs dont hit as hard
I have the JL Audio 250/1 hooked up to 2 kenwood 10s... and i had my full range infinity kappas just run straight from my radio. the problem is i recentelly installed a 2 channel amp to power my full range speakers but when i did this i lost how hard the subs hit... i added a capacitor to the power cable for the JL amp, and even ran a whole different power wire from the battery to the other amp to keep them seperate but my subs still arn't hitting as hard as they did and i even went as far as unhooking the other amp so just my JL would have power and they still didn't hit as hard... so please if anyone has any suggestions id love to hear them i want my subs back...also if it helps, both amps have seperate audio cables run from the back of radio

kappas are 2ohm. You are running that amp at 2ohms stereo on front and rear channels. That is a nice amp, but it is a thirsty one. If you have a sub amp as well, then you are not supplying your amps with enough power. drop down to 0 gauge and see if it heats up anymore. Also, try going high pass if you have subs. If you don't have subs. You need to run 4 gauge and make sure you have a great ground.
It could be a number of things? 1 to many subs, speakers wired to the amp causing it to overheat and making the thermal light come on. 2 It all depends were your amp is. If it's clear and nothing covering it, obstructing it, Ie sub in front of it, amp inbetween the rear seats and sub.
you dont want to connect both of those amplifiers together. You could run them separately to separate subs or the jl to your sub and your alpine to your front speakers. But you dont ever want to mix and match amps to the same sub. Even if you had 2 jl500/1's you wouldnt want to just hook them up together. Because they both have to be putting out the exact same amount of power. Which no 2 amps are ever exactly the same. Some companies make bridges to properly connect 2 exact amps together. I Hooked up 2 JL 1000/1's to each voice coil on a 13.5 W7 and i smoked the sub. So i definitely dont reccommend doing it unless the amps are conneccted to separate things.
make sure you have seperate power and gound seperate remote wires and if it does have a pass through then use it but i would hook up one at a time make sure they both work if after all this and it dont then your deck may not have enough power coming out of it to power the rca's or use y adapters from the cd player and run 2 sets of rca's.
number one did you install the subs youreself..it could be you have a double coil not installed right for full potential connect red to red and black to black on the back of youre spkr but if its a regular coil dont worrie about it ,,and also set amp to low pass and also bridge it so it would reach full potential .
Although amps with 5 channels are pretty rare, you can get one. Alpine, Boston Acoustics, Infinity, JL audio, MTX, and Polk all have 5-channels ranging in price from around $350 up to around $1,000. The Alpine PDX-5 will output 75X4 watts RMS for the front and rear stereo channels and 300 watts to the mono sub channel. It is priced at $599.99 at Crutchfield.
That amplifier is 900W x 1 @ 2ohms.
If your subs are 4ohm SVC wired Parallel, resulting in a 2 ohm load, each sub will only see 1/2 of the rated power. (450W ea.)
Your gain (sensitivity) setting should be between 75% and 85% to max. You will be fine.
Sounds like it should be an easy task (fitting the sub), but you will have to make sure that the JL 8" woofer has at least 1" to 1.5" in front of it to enable the sub cone to move freely (without obstruction). JL also offers a range of "ready made" sub enclosures on thier website (including kits for Tacomas), which could give you a good idea on mounting options.
The amp and speakers came out of a boat? That should be no problem if you plan to install these components into a car. Some companies (eg: JL Audio) have specific models which enable the use of thier products in marine environments, having components less susceptible to corrosion, U.V. damage and moisture ingress than thier equivalent car audio products.
Your JL amplifier part number E6440M has "M" added to the end of it's product name denoting it is intended for marine use, however you can use the same amplifier in a car without any problems at all. The power voltages will be the same, and the signal inputs are designed exactly the same. The only difference is that the marine version will have the added benefit of less corrosion problems :)
Just to make sure that the speakers aren't damaged (from corrosion) before fittment, check the motor and magnet basket assemblies (visually) for discoloration (particularly white salty residue).. These discolorations and residues should be removed as much as possible before fittment to a car environment, so as not to cause corrosion problems to your car later on down the track.
