20 Most Recent Theater Research TR-9500 Car Subwoofer Box Car Speaker Questions & Answers

ok..I just did alot of research on these. They are made in china and cost around $30. ..if you get them in china. I can't find any actual retailers anywhere...except for guys selling them out of the backs of vans. I guess a few street **** have scams going on where they buy hundreds of these things, then mark them up and sell them for $200-$800 on the street. That being said, almost everyone that bought them said they were actually good speakers.

Why would you hook up 4000 watt amp to a speaker that has only 1000 watts. Try a 800 watt amp instead unless you just dont want the spealers.

Sounds like you have burnt out something (as you probably already know LOL) but maybe you just over heated some wires that couldn't take the Amperage. If this is the case, you MUST find out:

Why there was so much Amperage there at the time
Why didn't the Fuse blow? (perhaps too high an Amperage fuse for the Unit?) and
Why could your unit not handle the Power? (perhaps not Rated for that Power Output?).

Note: Watts and Amperage are not Musical terms, they are Electrical terms. So an Amplifier Increases the output Current to a maximum level designated in various ways as PMP (common but misleading) RMS (the International Standard) and DIN (the mainly European standard). The receiving unit (in this case your sub woofer is designed to handle a maximum level of Current input and this is usually desribed (again misleadingly) as simply Wattage. The common factor here is that both your Amplifier and Sub woofer are probably using the PMP rating.

If this is the case then you can easily determine if the 2 units are compatible using their "Wattages". For instance, a 275 Watt amplifier is too much at HIGH outputs (volume) for a set of speakers Rated at 160 Watts (they will "blow") but will work fine at Lower volumes because the Amp is putting out less Power at Lower volumes and is therefore probably below the Speakers Maximum input range.

Conversely, it is OK if the speakers are Rated for higher inputs than your Amplifier can put out. For example, a 175 Watt amplifier is fine with speakers Rated for 240 Watts because it can never produce enough power to "blow" the speakers.

Just putting in heavier wires will almost certainly bow up the sub woofer if the initial problem is not solved.

Take it to a HI FI shop and get them to look at it. If they simply say "Can't repair these, buy this one", try another shop.

Sorry about the lecture.

Good luck.
