Soundstream Tarantula 800/5 needs repair Help!!

davedamage · 19th February 2009, 01:40 PM

I have a Soundstream Tarantula 800/5 (The Huge Chrome one with the Handles) Hooked up to a pair of Soundstream exact 10's in a ported box. When the volume is up loud and a lower bass note hits (say around 30hz or lower) the amp cuts out. If I turn it down a little then its ok. Anyone have any idea what this could be? any help would be nice. Thanks in advance.

IMOP sounds to me like u have to low of a laod on the amp.
OR maybe your subs cant handle the power from the amp and making the amp shut off.

First question how do u have your subs wired to the amp and are the subs single or dual voice coils and if dual coils how do u have them wired

Right, could be protecting because of low load or also could be you have a power problem like a bad ground or fuse holder/etc. If power drops to about 10v at amp they shut off. If the amp has an LED for power often they will dim down a lot if you have power issue.

I dont think the ohm load is the issue. The subs are Single 4's So I have them wired to a 2ohm load. Was fine for a year and just started doing it. I wired 2 Soundstream SPL 10's to a 4ohm load and the same thing happened. (Put the Exacts back it :-) I dont know whats going on lol

Check the volts at the amp with it cranked up, if it falls to 11v or less DC then that could be it. Is it getting hot? If you swapped the subs likely not them. Is that amp supposed to run 2 ohms on sub channel? Double check all wiring and connections just to be sure.

davedamage · 19th February 2009, 07:15 PM

The voltage is good. The amp is 2 ohm stable on the sub channel. I have not only double checked the wiring, I have triple checked it. I am so lost lol

davedamage · 19th February 2009, 07:16 PM

Also the amp runs cool.

jol50 · 19th February 2009, 08:13 PM

Did you bump the amp around a little to see if it has a short? I mean don't beat on it but could be something loose inside.

davedamage · 19th February 2009, 09:08 PM

yes I have, I have even wiggled wires when the volume was only a few clicks away from being at the point that it usually shuts down. Nothing.

Disconnect the speaker wires from one channel at a time to see if one speaker is causing the problem.
