sub not being driven enough?

dlagace · 25th November 2003, 02:04 AM

This is my first car audio install. I have a Clarion DXZ525, PG QX300.1 amp, and Bazooka single voice coil sub. All wires coming from the H/U are correct (when H/U is on, amp is on). The are no wires shorted out that I can find. The amp is bridged to the sub, but the sub seems like it isn't being driven enough. The amp is putting out 300W at 2 ohms, the sub can handle 300W. what could be the problem?

Hope it isn't too vague; Thanks for reading,
DL

maybe its a 4ohm speaker?

The sub is 4 ohms? Therefore your amp may only be pushing out 200w or so.

Also, your sub level is down too low, amp not turned up enough?

Box is poor design so restricting performance?

Fixed. Ended up being the source unit. I flicked the fade to the back, boom: everything works. Shut the car off, put the fader back to 0, sub miraculously comes alive. Very weird. Sorry for the trouble, thanks for the replies.
