I have a sony power sub model wg-450 and for house reciver somebody cut all of the wires on it now i have to find out how big of a power surple i need for it

Before you cut any wires, make sure the sub woofer can handle the power from the Sony. Is the sub powered? What are speaker specs on the Sony . Is the output jack on the Sony meant for an unamplified sub? You have to know the answers to all this so you won't blow up the Sony and/or the sub woofer

just do as I did cut the cable and attach to a store bought power adapter works good. I am only using a 12v power adapter and it seems to work fantastic

Problem could be that you need to upgrade your battery, do the "big 3" wiring by a professional. Get a kinetic 1200 or bigger to replace your stock battery, drive your car for 5 or 10 miles, and watch your amp not shut down. People just dont do the big 3, and they think their stock lead acid will hold 13 volts after the power is shut off. LOL. KINETIC.

You .need a 5.1 reciever. Run the sub and speakers to the reciever run the reciver to your cable or tv

Hello, I have a 2000 ES300 and while the body style is different believe the newer model still has the rear deck mounted sub-woofer that you are referring to. The process of removing this speaker would start off the same as if you were going to replace the third brake light also located in this housing. Using a flathead screwdriver work your way around prying/popping up all four corners of the speaker grill covering the speaker that have the retainer clips. Once you disengage the clips work/maneuver the grill up and towards you gently and it should slide out. The bulb for the third brae light will be attached to this speaker grill, disconnect the snap wire from the bulb and you should have a clear visual of the speaker and the four bolthead screws securing it. Remove these screws and your almost home free. The next part might be slightly more difficult. If the speaker s simply connected by a clipped on wiring harness, just detach.On my 2000 ES300 i have the pioneer system(Not Nakimichi) and the 2 wires (one black, and one red) are soldered directly to the speaker. You can take a soldering iron(maybe a battery or gas powered one unless you have an inverter) and remelt the solder to remove the wires or you can elect to simply cut the wires. If you choose to cut them make sure you cut them as close as possible to the soldered joints so you have plenty of wire left to install the replacement speaker.Then install replacement either soldering or using crimp clamps and reassemble. ( Note if you simply want to add a aftermarket amplified sub-woofer you don't need to remove the sub-woofer out of the housing. You can tap into the wire leads and run it directly to the amplifier. Just cut one of the wires leading to the stock sub-woofer so it doesn't also come on and potentially blow while the radio is on. This will also prevent any bass humming when the radio is shut off but the aftermarket amplifier is still on because once one of the wires to the stock sub-woofer is disconnected or cut it breaks the circuit. Hope this helps.

if your amp is overheating your sub is needing to much power that the amp doesnt have.
if its cutting out and the red light comes on you need to check the wiring. nothing not even the tinyest speaker wires can be touching.
proper wiring would be your best bet.
but i would upgrade amps.
cheap bang isnt reliable.

Switch your blue wires around.

You have put the remote antenna wire to the remote turn on of the amplifier. The radio cuts off the power to the "power antenna" when you switch to a different mode... so your amplifier is now losing the turn on signal it requires to stay on.

Simple 2 minute fix.

hey buddy, I have the same system, and although I haven't experienced it on this one, I had the Harman Kardon equivalent to the TSS-750, and the sub did this same thing. It was a loose RCA connection, and, as I was well outside of warranty, I took the amp out of the back and just re-soldered the connection myself. It now functions flawlessly for my bedroom setup. I hope you get it all worked out on your system! I can't imagine using this awesome system without its deep notes!

The best thing to do is to get a amp that is more watts than your subs, not the other way around, speakers are known to handel a lil more power but amps cant produce more power than they are capable of... your ground wire should be thick also, say 6 to 8 mm or so, and its best to put in a cap and an equalizer.
Cheers

it might be that your wires from your amp to your subs are too thin. since they were relatively new the first three months, they were probably undamaged, but after pushing them too much, they probably have broken wires, and can't get enough power to the subs when turned up, i suggest getting thicker wires before investing in a capacitor, it could save you money.
